I was working at a local computer recycler a few years ago, when I was given an old Macintosh Plus to trouble shoot. I turned it on to discover that the the CRT did not seem work, so I followed my instinct. I gave the computer a good whack, then it lit up bright and sharp as ever. Immediately following this, I uttered a loud "Ayyyyyyyy."
I tend to Fonzie all of my electronics. For instance, prior to repairing my OG Xbox, they disc drive would get stuck. Giving it a good whack usually solved the problem.
Safety Warning: The fire extinguisher you're using doesn't work, it's on the Consumer Reports "Don't Buy: Performance Problem" list because when you attempt to use it, the trigger mechanism will often break and it won't discharge (Amazon reviewers complain of the same thing). I'd recommend a 2.5lb standard ABC fire extinguisher for small uses like that. More generally, you want the largest extinguisher that all potential users can comfortably lift and use, which is often 10lbs (weight is for the extinguishing chemical and doesn't include the tank and such). Sorry about the unrelated nitpick on your great video :)
Did you really just randomly look up the fire extinguisher? Or did you somehow already know about this specific fire extinguisher before watching? Either way it's bizarre lol.
When CRT's aren't used for decades they have a very dark picture. This goes away after some used. I don't know what the exact cause is be it a reaction in the phosphors in the tube or corrosion. On a podcast I heard about a really old and rare computer that had a lot of work put into it but once it was working the screen was so dark that it was unusable. After about a month of being left on the screen had gradually recovered back to normal brightness.
I believe it has to do with oxide buildup on the phos. Eventually the electrons liberate them and all is well. At least I have a memory of that being a thing. I'm not swearing to it though. It could've been oxide buildup on the aluminum also. Can't recall specifically. Going to search it now though.
Probably to do with the electrolytics in the power supply and decoupling, reforming and the supply voltage rising and stabilizing... this happens IFF they don't asplode first :-/
and if you're worried about burm-in, that was mostly a thing in the eighties and earlu nineties, by the late nineties and 2000s burn in wasn't really as much of a thing anymore, and a hypothetical 2020s CRT might eliminate it even further.

The reason why there’s less of the proprietary keyboards is Apple used a cable that has the data and power lines swapped on one end, and many people used standard RJ phone cables, which sent power through the data lines and fried the microcontroller
OMG the memories! Our family's first computer was Macintosh Plus. It became my sister and I's computer in 1995 - we were 3 and 5. From 1987 to 2002 it worked with absolutely zero issues, but then it simply never turned on again. I guess it would've been possible to repair, but my family put a lot of their money into buying eMacs and a new iMac at that point which tbh was the best thing to invest in at that time. I miss our Macintosh Plus so much. I drew a lot with that machine! My dream is to own one again in the future.
I've watched a lot of youtube instructional videos. I'm not even interested in restoring a macintosh plus, but watched this whole thing because it is so interesting and this guy is awesome.
Hi! Young computer lover here! My grandad gave me one of these about a month ago and we decided we would try and get it starting for the first time in a decade. When we took it out of the tub it had been in for the past so many years, it was all covered in dirt and wet rust was pouring out of one side. I cleaned it up and left it on its side to finish draining and drying for a few days. Luckily, the keyboard and mouse had been kept in much better conditions and were alright. When the time came, My Grandad sorted out an extension lead just in case we blew the electics, and i sat and recorded from the front. The fan started up, and there was this buzzing noise. It could have been blowing itself up for all we know. Alas, i still keep it in my room amongst my other old computers. Its truly beautiful though, and i would have given anything to grow up in a time where this was the normal tech :)
You can convert a high-density disk to a low-density by simply covering the density hole. Furthermore, the old drives don't actually check this hole, so they will happily format the new disk with a low-density format and use them, you just can't interchange them.
@@The8BitGuy I tested two years later and found no issues with the HD floppies written in my Amiga 600 at double density. Now they're five years old and need to be tested again. hmmmm
Story time: Back in 1997 I had just started adulting and was working at a newspaper. They had these available in the newsroom and they were old enough that some of the menus had burned into the screen (screen savers weren't just for when you got bored back then). So some of them weren't working and our cheap manager was trying to repair them instead of upgrading. He called the only person he could find that had parts. After they had been talking for a while, the supplier asked him where the intended to display them. Cheapo manager was like, "display them, what do you mean?". The supplier said, "Well are you going to have them where someone can touch them, are they going to be on, are they going to be behind glass or anything like that?". When the manager said he wanted to repair computers so people could work on them supplier guy freaked out. "YOU HAVE PEOPLE USING THESE? LIKE RIGHT NOW? I THOUGHT THESE WERE FOR A MUSEUM!?!?!" Bottom line, we never got the parts and got some newer (used) computers.
These computers or at least very similar ones to these were in the free access computer room when I was in high school in the mid 90s. I spent hours on them playing the game Oregon Trail. Was great fun.
i do love the fact that you don't cut any video out if it doesn't go to plan, it shows that you are very experienced with this kind of thing but things don't always go the way you hope, must take a lot of time and dedication to make videos like this when restoring machines, great content creator! :)
Great video, as always. My guess is you're using rosin core solder, but I would also recommend using flux. AMAZING DIFFERENCE. Less time applying the solder iron, which prevents damage to components. Solder transfers much more smoothly over evenly heated area from the flux, preventing cold solder connections. A stiff bristled brush and rubbing alcohol can remove the excess. You'll probably never solder without flux, ever again. The information you were given about electrolytic capacitors is correct. Some newer caps have different or improved materials, along with the electrolyte. They tend to have better tolerances and be more durable. Very "Pro" move using shrink tubing to insulate the leads on the poly-cap. At the beginning of the video, I said to myself that the age of these Macs has probably killed the electron-gun. When you had the dim screen, and made mention of it, it just validated my thought. Quite sure that's the issue. Hopefully, the replacement tube doesn't also have an issue. On rare occasion, you can fix the brightness of the tube by increasing the heater voltage of the tube, but you'd need to first get the current voltage across the heater, and then look online what the max voltage should be. You can then work on the circuit to slowly adjust the voltage up. That's a bit more work, and sounds like you might have a spare screen available. Good to know you have options, though. And keep coming with the videos. I just love 'em.
+Doramius My father told me about devices you used to be able to buy for old color tube TVs that had failing picture tubes that were getting weak called 'Brightness Boosters' and other similar names; you plugged them into the back of the CRT in front of the regular connector and they would boost the voltage and increase the brightness. He also told that they were a temporary fix and that pushing the tube voltage that high would make the tube fail even faster until it failed completely; he said they could be dangerous and were not a good idea.
To make easy the desolder process, just add new solder to the solder joint that you want to remove, the old solder will adhere to the solder wick way more easily than just melting the old solder...
@@andycraig7734 I love 8bitguy but watching him desolder was pure torture. Reminded me of when I first started. We all have our skill areas, I suppose.

@@carspottingconnecticut1582 you should believe it. We used to get dozens and dozens of those old computers in the trash and we would just send them right to the landfill. When I worked for the trash company you would be surprised how much old and new stuff in the Box got thrown away
I love your videos! Especially the C64 videos. Random factoid: I work with a lady who worked at Commodore back in the day as tech support for the VIC20 and C64.
I love these old machines, so much practicality and function over form. It makes it feel like it has a greater purpose than just an everyday device, could you imagine? Slipping off a conversation to say something so sophisticated. "I'm off to use my _computer_ ." Such honesty, such boldness, such *brutal* power!
Our school had these Macintosh Plus computers. This was the first computer I used. I think I was around 7. The year was -95 or -96, so these computers were then 10 years old. So much nostalgy.. Nowadays I use a computer almost every day of the year and for me it started with this computer. Thank you very much for this video. Liked & Subscribed.
my third vintage computer is a macintosh classic and it was free it works but i had to get a ADB mouse and keyboard connector witch was about $30 total and it works!!! i love your macintosh videos please make more
Pro tip when removing hot glue. Take some canned air, turn it upside down and spray the liquid straight onto the glob of glue. It temporarily hardens and contracts the glue making it pop right off.
I dont know how much help i can be here but my very first computer was a Macintosh Plus. My mom was an at home nurse and one of her patients parents had it, it was broken, and they gave it to my mom. My grandmother was the computer person at the time (she was a special ed teacher) and was actually part of the local Macintosh Users Group, and i used to go to her monthly meetings. Ok long story short, this was about 1994, so it was an old system already. My grandmother got me trackball for the mouse, and as far as I know it was just a serial port trackball for a PC. I can't remember what i had for a keyboard. It may have been the original keyboard for all I know. I wish my parents had kept the old system but when I got my Performa 550 a year later for my birthday the Mac Plus disappeared. I was 7 when i got the plus, 8 when i got the performa 550. Anyways, thanks for the trip down memory lane. That computer sparked a life long love affair with computers. Although i'm not as big into them as i once was, but part of growing up i guess.
If you are unsure about starting an open machine like he did in this video, you are safer off by switching the power switch to the ON position while the machine is still unplugged from the wall outlet, and then start it by plugging it in, then you don't have to be just as close to the machine if something were to go wrong.
You can pick up a vacuum bulb for sucking up solder for just a few bucks too. A wire wheel to remove scale and some tinning paste is always helpful for soldering irons that don't work like they used to.
Tandgnissle To make desoldering a cap easier, add extra solder to the solder joint. This way you increase the contact area between the tip and the leg.
So much the flux. Add it to the wick. I have a pen-type dispenser that's really nice and fast and easy - you'll be amazed how much faster de-soldering becomes.
you are just amazing, thanks. I have one of these given to me a few weeks ago. didn't need to worry about the board or tube, just found a fuse missing from the mains plug, put a 5 amp fuse in and all works fine. my project is to work out how to use a one button mouse and then to see if I can work out why the printer has lights flashing. thanks again.
Just as I play no musical instruments yet love to hear classical music, likewise I know absolutely nothing of electronics yet love to watch these videos. They are easy to follow and enjoy even for the novice - also something very calming to watch… despite the hard work you clearly invest in your projects. Excellent work as always on this video - suffice to say, I won’t be rushing out to buy any vintage 80’s Macs anytime soon. I’ll stick to my trusty 12 year old MacBook pro.
I passed on buying one of these macs at an auction last Saturday and after watching this I'm glad I did. Definitely looks like something that requires more investigation and probably a couple spare units to get a working one.
David a few years ago, I could format HD discs in my PC as DD easily, the only thing needed was to block the second hole! Then I could use them in my Amiga 500 without an issue! Also, indeed this episode was a LITTLE long. Please make them longer! 8)
@@andycraig7734 If I remember correctly HD discs were unreadable on my A500, unless formatted at DD 720KB in the PC. Also if I didn't cover the HD hole when using it on the PC it would refuse to format it at DD 720KB, it would only format it at HD 1.44MB.
Because of differences in the design of the Apple 400 and 800K drives it is impossible to write disks for them using anything else than a 400 or 800K floppy drive
I never put my hands on a vintage computer but i really enjoy watching you digging through all these little parts and pieces!! Nice job, love your vids!
Very nice, I'm glad to see you were at least able to get this thing to power up and display something. Crossing my fingers the CRT replacement works out for you.
Did you ever try the spare CRT? When you mentioned the screen gets blurry when you crank the brightness up - right away I knew the CRT was worn out. That is a classic sign or a worn out high hour CRT. Being the logic board was bad as well it’s safe to say that that machine was used a lot and someone got their money out of it for sure! Very good video as always
you would think that but I have a macintosh from MIT that just had cooked resistors for being used 24/7 and yes I know crt's die but I see them more in the color spectrum haveing multiple guns for different colors and when they first started getting into all transistors in the early 70s could also contribute to the way that tv crt's die macintosh's not so much other than burn-in but Davids looked fine to me
Years ago when I worked as an Apple Systems Engineer I replaced hundreds of these analog boards. We always adjusted the +5 and +12 volt supplys. The pots each had to be balanced with each other. This really brings back memories. Love your channel.
Damn this brought a tear to my eye. Back in the early 90's I worked part time (after my day job) as an after market Mac Repair Tech :) I had a great collection of mac's with a couple of thousand floppies of software. Lots of peripherals (even shared a HP A3 colour scanner between a PC and my mac's) The poly cap is a good choice for the flyback circuit. I would agree the tube looks aged as the blooming (going out of focus when you turn the brightness up) is happening at a very low brightness level. I would love to still have all my old stuff (not that I have the room to store it all :(
lump of blutack worked for years for me :) Ahhh the days when technology wasn't miniaturised to the point where you can no longer pick the pieces up individually! SD card parts are a different story lol.
I have been doing a lot of soldering lately, and my 10c is that using a flux on the solder joint (syringe with gel or liquid) will make the solder wick braid work IMMENSELY better, and the new solder will work a lot better as well. Awesome videos by the way!
I can barely understand any of what you say but I've been binging your channel and it's really, quite fascinating stuff. I wish I would have grown up tinkering with computers like this.. I think it would have been a good fit for me. Thanks for sharing your passion!
@The 8 Bit Guy hey 8 bit guy, you are the BEST channel that i have watched so far, keep it up, I have one quick question since you know about them the most, what is the difference between the Mac Plus and SE? To the naked eye they just look like different body designs, but i would assume that it is more than that. If you explained this during the video, i got cut off at 3:12 for some reason. Thanks :)
Nice video. I had a 512K given to me about 15 years ago that still works fine. The screen is nice and bright and boots up in just a few seconds. It came with a mouse but no keyboard. I've thought about getting one but as you mentioned they are on the pricey side and if I did have one, well what I am going to do with it. As it is I can still show how it works. Its almost like a working time machine taking us back to a time when personal computers were uncommon household items, considered very high tech, and relatively quite expensive. Thanks for sharing your gear with us.
Always love your videos...but please, please, next time get some all plastic tv adjustment tools...I cringed when you reached across the high voltage area with your metal screwdriver.
I mean it was bad enough he turned it on without the back on given the voltage at work here. Then he used the screwdriver and I was like "Christ do you want to die?"
Why not blame proprietary practices instead? Supply and demand is going to do what it does regardless of buyer or seller. If it hadn't been created by the proprietary issues it wouldn't be occuring.
Hello 8-Bit Guy :) I really want to say thank you for sharing all your tech stuff with us. Since I've watched your first video I've been so impressed of old technology, thats simply amazing. It's a lot of fun to see how professional you restore your computers and it is education too. Keep up your good work, I really like it! :)
What a great episode with a lot of suspens ! And it's impressive all the job you've done on this machine ! I was glad to see the final result even if there is still a problem.
iMac G3s are an easier start especially the slot-loaders they are not that expensive if you wait around on eBay i got mine a few months ago for £10.50 with mouse and keyboard and it was mostly working
Sapher I beg to differ, as the flux in the braid can be of poor quality, and even more importantly, there isn't really that much of it. Also, you need more flux for desoldering than soldering
you should use the 1.44mb disk when you can just block that hole who are on the other side. i remember we buyed 800/2720mb disk and drill the hole and thatr worked
I was wondering that for some time now, if I should have just drilled the second hole for using my amiga disks in my PS/2 back in the day. Are you sure that would've worked?
When you're soldering, don't be afraid to turn the temperature up. If the solder stays clumpy and doesn't melt all the way within a couple seconds, try turning up the iron. That way, you don't lift traces on the PCB or damage components from prolonged heat exposure. Loved the video btw!
That's what I started on before getting my first x86 PC. People will likely have divergent views on the best beginner machine, as the popularity of Apple has changed a lot since the early 90s.
Great video. I just pulled out Mac Plus after 25 years of ignoring it and it did boot from the System 6 floppy but didn't from the external hard drive. No amount of cable changes or terminators worked. In your video I noticed the Disk Tools disk, I should try it. Otherwise, the other day I came across a product that emulates a SCSI drive with a SD card, two actually, BlueSCSI and ZuluSCSI. They are far cheaper than a solid state drive.
I think this is just great, the fact that you're sincere about the unknown factors here is what makes this really interesting and entertaining to watch. Looking forward to the next chapter! 😃👍🏼

Yes.. but I've found the data tends to degrade over a few years when you do that. Otherwise, a disk written in its correct density will last forever.

I used to work for a trash company I'd see dozens of them. One of them was even in the Box once
I found my firstborn in a dumpster.
No you didn’t
@@carspottingconnecticut1582 you should believe it. We used to get dozens and dozens of those old computers in the trash and we would just send them right to the landfill. When I worked for the trash company you would be surprised how much old and new stuff in the Box got thrown away
I love your videos! Especially the C64 videos. Random factoid: I work with a lady who worked at Commodore back in the day as tech support for the VIC20 and C64.
I love these old machines, so much practicality and function over form. It makes it feel like it has a greater purpose than just an everyday device, could you imagine? Slipping off a conversation to say something so sophisticated. "I'm off to use my _computer_ ."
Such honesty, such boldness, such *brutal* power!
Your thoroughness in method keeps me coming back to these videos. Bravo!
This song is pretty great
This is such a fun channel to watch. It reminds me of TechTV.
Party at David's house:
"Don't use those plates; they're for mixing epoxy!"

I found oil for salad dressing, but where's the vinegar David?
Our school had these Macintosh Plus computers. This was the first computer I used. I think I was around 7. The year was -95 or -96, so these computers were then 10 years old. So much nostalgy..
Nowadays I use a computer almost every day of the year and for me it started with this computer. Thank you very much for this video. Liked & Subscribed.
my third vintage computer is a macintosh classic and it was free it works but i had to get a ADB mouse and keyboard connector witch was about $30 total and it works!!!
i love your macintosh videos please make more

Proprietary, expensive, hard-to-replace hardware? Oh that definitely doesn't sound like Apple at all - lol
Handsome_Hero they’ve been like that since the mid 90’s.
God those Macintosh's have give up written all over them
"fixing this will cost $800, you're better off geting a new one."
Also a 25 year old machine still going strong, that’s pure Apple too, haters
@@pb7379-j2k Yeah, a lot of other old computers can do the same if you repair them
Pro tip when removing hot glue. Take some canned air, turn it upside down and spray the liquid straight onto the glob of glue. It temporarily hardens and contracts the glue making it pop right off.
I'd be careful about doing that in close proximity to any older plastic parts you don't want damaged...
I dont know how much help i can be here but my very first computer was a Macintosh Plus. My mom was an at home nurse and one of her patients parents had it, it was broken, and they gave it to my mom. My grandmother was the computer person at the time (she was a special ed teacher) and was actually part of the local Macintosh Users Group, and i used to go to her monthly meetings.
Ok long story short, this was about 1994, so it was an old system already. My grandmother got me trackball for the mouse, and as far as I know it was just a serial port trackball for a PC. I can't remember what i had for a keyboard. It may have been the original keyboard for all I know. I wish my parents had kept the old system but when I got my Performa 550 a year later for my birthday the Mac Plus disappeared. I was 7 when i got the plus, 8 when i got the performa 550.
Anyways, thanks for the trip down memory lane. That computer sparked a life long love affair with computers. Although i'm not as big into them as i once was, but part of growing up i guess.
If you are unsure about starting an open machine like he did in this video, you are safer off by switching the power switch to the ON position while the machine is still unplugged from the wall outlet, and then start it by plugging it in, then you don't have to be just as close to the machine if something were to go wrong.
Use flux, it makes it a lot easier to desolder stuff. A new tip wouldn't be bad either.
You can pick up a vacuum bulb for sucking up solder for just a few bucks too. A wire wheel to remove scale and some tinning paste is always helpful for soldering irons that don't work like they used to.
Tandgnissle To make desoldering a cap easier, add extra solder to the solder joint. This way you increase the contact area between the tip and the leg.
So much the flux. Add it to the wick. I have a pen-type dispenser that's really nice and fast and easy - you'll be amazed how much faster de-soldering becomes.
Omcsesz it's called tinning isn't it?
NO. It's normal electronical soldering. It's just for increasing the contact area.
It's... It's...

I have always covered the hole on the disk to convert it from HD to DD. Some may be against this, But i have not had any problems doing this.
I worked for Apple as a Field Engineer back in the day. These videos bring back memories.
you are just amazing, thanks. I have one of these given to me a few weeks ago. didn't need to worry about the board or tube, just found a fuse missing from the mains plug, put a 5 amp fuse in and all works fine. my project is to work out how to use a one button mouse and then to see if I can work out why the printer has lights flashing. thanks again.
No matter how old these machines are, watching them working is always soothing.
you deserve so much more subs
He's closing in on 500k subs. That seems pretty damn good to me.
AnimeChuck he deserves at least a 1 mil his content is entertaining and educational
Aaand he’s over 1 million, can’t wait to see his new play button on the wall
Lol retroactively reading these comments is great
Guess how many now?? Lol this channel is so good!
never clicked on a video so fast
I really enjoy these videos! As a modern engineer-to-be, these old machines never fail to fascinate me.
I'm still in awe of your back wall. Makes my OCD, my OCD, my OCD feel right at peace.
Why am I watching this?! I have no interest in computers, but I'm addicted. You're like the Bob Ross of computers.
Looool best description ever!!!!
*Insert vaporwave meme here*
Im always excited to see you im my subscription box. Great video!
Just as I play no musical instruments yet love to hear classical music, likewise I know absolutely nothing of electronics yet love to watch these videos. They are easy to follow and enjoy even for the novice - also something very calming to watch… despite the hard work you clearly invest in your projects. Excellent work as always on this video - suffice to say, I won’t be rushing out to buy any vintage 80’s Macs anytime soon. I’ll stick to my trusty 12 year old MacBook pro.
I dont know why but your videos makes me calm. It is good to watch them at the end of the day :)
You can use HD disks as DD disks most of the time. When you use them on a HD drive you need to cover the 2nd hole with tape.

Cool I love your channel it is very entertaining and I'm learning a lot of stuff about computers still your channel is awesome!!!
I passed on buying one of these macs at an auction last Saturday and after watching this I'm glad I did. Definitely looks like something that requires more investigation and probably a couple spare units to get a working one.
keep up the good work. love the retro vibe and learning about some of the old stuff i missed out on.
This is an interesting hobby to have. It's very hands on and involves problem solving, plus you could die from massive electrical discharge.
So it's a bit like owning an iPhone 4 then
Dying is fun.
Back in the day we'd just cover the HD hole on the 3.5" floppies with a file folder label and then reformat to double-density.
David a few years ago, I could format HD discs in my PC as DD easily, the only thing needed was to block the second hole! Then I could use them in my Amiga 500 without an issue!
Also, indeed this episode was a LITTLE long. Please make them longer! 8)
@alysdexia Obvious -> Derp
@alysdexia ?¿?¿?¿?
Yep, though you don't even need to cover the HD hole if the disk drive has no HD capability such as in most Amigas.
@@andycraig7734 If I remember correctly HD discs were unreadable on my A500, unless formatted at DD 720KB in the PC.
Also if I didn't cover the HD hole when using it on the PC it would refuse to format it at DD 720KB, it would only format it at HD 1.44MB.
Because of differences in the design of the Apple 400 and 800K drives it is impossible to write disks for them using anything else than a 400 or 800K floppy drive
I never put my hands on a vintage computer but i really enjoy watching you digging through all these little parts and pieces!! Nice job, love your vids!
Very nice, I'm glad to see you were at least able to get this thing to power up and display something. Crossing my fingers the CRT replacement works out for you.
"It's impossible to find a computer that can write to these disks"
Druaga1 laughs at your statement.
he's not Druaga1 he lacks Druaga1's knowledge of the internet so give him a break
For the next PO box, someone should send "Fancy Soldering Equipment"
Did you ever try the spare CRT? When you mentioned the screen gets blurry when you crank the brightness up - right away I knew the CRT was worn out. That is a classic sign or a worn out high hour CRT. Being the logic board was bad as well it’s safe to say that that machine was used a lot and someone got their money out of it for sure! Very good video as always
you would think that but I have a macintosh from MIT that just had cooked resistors for being used 24/7
and yes I know crt's die but I see them more in the color spectrum haveing multiple guns for different colors and when they first started getting into all transistors in the early 70s could also contribute to the way that tv crt's die macintosh's not so much other than burn-in but Davids looked fine to me
Years ago when I worked as an Apple Systems Engineer I replaced hundreds of these analog boards. We always adjusted the +5 and +12 volt supplys. The pots each had to be balanced with each other. This really brings back memories. Love your channel.
Love the dramatic techno music while you reassembled the computer! The anticipation is killing me!
Damn this brought a tear to my eye. Back in the early 90's I worked part time (after my day job) as an after market Mac Repair Tech :) I had a great collection of mac's with a couple of thousand floppies of software. Lots of peripherals (even shared a HP A3 colour scanner between a PC and my mac's)
The poly cap is a good choice for the flyback circuit. I would agree the tube looks aged as the blooming (going out of focus when you turn the brightness up) is happening at a very low brightness level.
I would love to still have all my old stuff (not that I have the room to store it all :(
you can just tape the second hole on a 1.44mb floppy to make it a 720k you just hsve to format it
lump of blutack worked for years for me :) Ahhh the days when technology wasn't miniaturised to the point where you can no longer pick the pieces up individually! SD card parts are a different story lol.
Daily Corvid Yes these days everything is far to miniaturised to have any hope.
Yes I can see why you don't work on those machines. Though 'high voltage' is a all I need to not want to work on those machines.
I have been doing a lot of soldering lately, and my 10c is that using a flux on the solder joint (syringe with gel or liquid) will make the solder wick braid work IMMENSELY better, and the new solder will work a lot better as well.
Awesome videos by the way!
I can barely understand any of what you say but I've been binging your channel and it's really, quite fascinating stuff. I wish I would have grown up tinkering with computers like this.. I think it would have been a good fit for me. Thanks for sharing your passion!
You can use an old SCSI Iomega ZIP Drive as HDD. It is fast enough. Unlimited Storage.
I wonder if you could replace the floppy drive with a ZIP drive...

For it's time, the macintosh plus was pretty ａｅｓｔｈｅｔｉｃally in my opinion
Zen and the art of fixing vintage electronics, thanks for the video!
From what I understand some of the capacitors are high frequency and vibrate a lot, so they put glue to make sure it doesn't stress out.

@The 8 Bit Guy hey 8 bit guy, you are the BEST channel that i have watched so far, keep it up, I have one quick question since you know about them the most, what is the difference between the Mac Plus and SE? To the naked eye they just look like different body designs, but i would assume that it is more than that. If you explained this during the video, i got cut off at 3:12 for some reason.
Thanks :)
Why do I like the Macintosh Boot Sound?
8 bit guy don't worry making the videos long i love to see all the steps you always do even when you fail we all learn from that to
Nice video. I had a 512K given to me about 15 years ago that still works fine. The screen is nice and bright and boots up in just a few seconds. It came with a mouse but no keyboard. I've thought about getting one but as you mentioned they are on the pricey side and if I did have one, well what I am going to do with it. As it is I can still show how it works. Its almost like a working time machine taking us back to a time when personal computers were uncommon household items, considered very high tech, and relatively quite expensive. Thanks for sharing your gear with us.
Always love your videos...but please, please, next time get some all plastic tv adjustment tools...I cringed when you reached across the high voltage area with your metal screwdriver.
youbecha64 that bit got to me too holy crap talk about taking your life in your hands
He did mention it hasn't been plugged in for 2 years.
At the end, while the tube was powered up, he was adjusting the video settings with a steel screwdriver across the high voltage area.
I mean it was bad enough he turned it on without the back on given the voltage at work here. Then he used the screwdriver and I was like "Christ do you want to die?"
Well that is how you adjusted the CRT. I done the same with Tube TVs too. The trick is you would use a long taped up screwdriver.
Reason for expensive keyboards and mice: Stupid scalpers taking advantage of desperation.
Yes, scalpers see the world like this: Old=Rare=Expensive=PROFIT.
@Nigel Cam idk sounds like victim blaming to me
Nigel Cam absolutely correct, guilty buyer as charged, when I want something, I will pay what ever it takes to obtain it.
Why not blame proprietary practices instead? Supply and demand is going to do what it does regardless of buyer or seller. If it hadn't been created by the proprietary issues it wouldn't be occuring.
@@MekareP What are the proprietary practices? Do they limit manufacturing/distribution or fix pricing?

Hello 8-Bit Guy :)
I really want to say thank you for sharing all your tech stuff with us. Since I've watched your first video I've been so impressed of old technology, thats simply amazing. It's a lot of fun to see how professional you restore your computers and it is education too. Keep up your good work, I really like it! :)
What a great episode with a lot of suspens ! And it's impressive all the job you've done on this machine ! I was glad to see the final result even if there is still a problem.
iMac G3s are an easier start especially the slot-loaders they are not that expensive if you wait around on eBay i got mine a few months ago for £10.50 with mouse and keyboard and it was mostly working
Please add some fresh solder and use rosin or some other flux while desoldering.
there's flux embedded in the soldering wite, no need for extra flux, specialy for desoldering
Sapher I beg to differ, as the flux in the braid can be of poor quality, and even more importantly, there isn't really that much of it. Also, you need more flux for desoldering than soldering
you should use the 1.44mb disk when you can just block that hole who are on the other side.
i remember we buyed 800/2720mb disk and drill the hole and thatr worked
I was wondering that for some time now, if I should have just drilled the second hole for using my amiga disks in my PS/2 back in the day. Are you sure that would've worked?
Great stuff man it was indeed a lot of fun to watch. I'll be looking forward for future updates
When you're soldering, don't be afraid to turn the temperature up. If the solder stays clumpy and doesn't melt all the way within a couple seconds, try turning up the iron. That way, you don't lift traces on the PCB or damage components from prolonged heat exposure. Loved the video btw!

The best beginners machine is a C64
That's what I started on before getting my first x86 PC. People will likely have divergent views on the best beginner machine, as the popularity of Apple has changed a lot since the early 90s.
Yes, if you can find them.
14:38 Something's wrong, I can feel it
Got really excited the moment you switched on the mac, thanks for the repair!
Great video. I just pulled out Mac Plus after 25 years of ignoring it and it did boot from the System 6 floppy but didn't from the external hard drive. No amount of cable changes or terminators worked. In your video I noticed the Disk Tools disk, I should try it.
Otherwise, the other day I came across a product that emulates a SCSI drive with a SD card, two actually, BlueSCSI and ZuluSCSI. They are far cheaper than a solid state drive.
