Thank you so much!
Perhaps the most important machine of my formative years, an IBM 5160 has finally graced my bench! This machine is probably had the greatest influence on my interest in tech. It provided my earliest experiences with hardware and software, ultimately leading to a successful career in tech. Sure we also had a 5150, but I much preferred the 5160 because I was obsessed with hard drives as a kid. So when this system turned up in one of my e-waste hauls, I couldn't be happier!

Words to live by.
I came down just to comment on this. Man, this should be your merch slogan.
As my old boss used to say, "There's nothing more permanent than a temporary fix" :P
There's nothing more permanent than a temporary fix, that work
A 90 minute MikeTech video? Perfect way to spend the evening.
Came for the muscles, stayed for the tech 😁
Would love to see a board level repair on a hard drive, no one really goes that far when fixing one.
Mike knows exactly how to attract us in the thumbnails...
...and at 0:58 😛
Outta pocket 😂
ain't gonna lie on that 😚

Get you someone who looks at you the way Mike looks at vintage computers
Without the dismantling part hopefully 😅
Just to date myself, I used that same machine in high school for my freshman keyboarding class. Dual floppies. No hard drive. And the warm glow from the monitor.
Holy Biceps! 💪 👀
You can tell he keeps in shape! 💪
Carrying XTs around will do that
Setting a strong (hoho) example.
His shoulderblades will cut you.
I wish he'd do a workout video one time,I want to hear his routine!
The beard, the biceps. Oh yes and the vintage PCs are pretty amazing too 🙌🏻
You weren't wrong about this being a feature length film & it was totally worth it!
I'm curious if the faceplate from the non working drive fits onto the ST-225? Also I would use Speedstor to low level that non working drive. It might work better than the ROM utility since it will do a proper verify pass.
Looks like the faceplate won’t bolt up directly, but swear I’ve seen something similar done. It was a very long time ago though, probably mis-remembering. I’ll give the Speedstor LL format a try. Really want to see this drive work. They are quite expensive these days.
Thanks for showing us your Six Pak on video. :) And the exact same "tantrum" capacitor blew on my CGA card.
Figured I might as well since people keep asking. 😂 Yup, the C8 cap failure is common enough to have a page on minuszerodegrees.net
Seems it just filters power to the header for a light pen, so completely unnecessary (unless using a light pen).
Mike, your granular knowledge of this pc's innards, is just awe inspiring.
I would have given up, very early in the fixit process. Oh man. You are the GOAT of geeks. Nobody else gets down and dirty like this. Nobody else sticks with it until the comp is running and usable for real!
HUGE RESPECT, dude!
My first experience with computers was the IBM 5160 back in 1988 when I was 11. My maths teacher got me to copy a disk onto multiple disks using the copy disk command in PC-DOS to copy from the A drive to the B drive. I don't think it had hard drive as it had two 5.25" floppy drives. By 1991 I was really confident using computers running Windows 3.0, and was the start of my early hacking days by hacking into other students accounts and messing up there work by altering or deleting documents. I only done that because I suffered really badly with being bullied at school and was the only way I could get revenge without being noticed. Thank you for the good memories in restoring it, and I'll soon re-forget the bad memories again.
Revenge is so sweet especially when deserved.
This MikeTech video turned into an Adrian's Digital Basement video!
This video contains almost everything one can encounter when dealing with old PCs. Even a little smoke show. Awesome!
I love how excited you seem to be by finding old hardware related to your childhood. I'm so happy for you, i would be the same if I found the computers from my days.
This was my first pc in the early 90s, only difference was that I had an MDA card. It was already obsolete by then but it was mine. I have no idea where it went after I got my dad's old 486, kinda sad. Thanks for the trip down nostalgia lane.
This was my first PC also! It looks so familiar... that huge floppy and HDD look... it's wonderful to see.
Now I remember why I hate tantalum caps . You have more patience than I have these days, but I remember doing all this way back in the 1980s.
Excellent effort reviving this dinosaur Mike 😃
There's nothing more permanent than a temporary solution that works.
I love the older IBM stuff mostly because i missed most of it
I can't believe you hand started that hard drive! I guess that's how you know it's old.
more e-waist videos I'm ready
I had one of these machines for years. 640KB & CGA w/original monitor. It was so clean inside you'd think it was barely ever used. The hard drive, which I do not believe was original, was a half height 32MB Seagate. It did not spin up, but everything else on the system worked. After years of 'I'll get to it someday' I sold it to a local collector who was going to restore it. I hope it's been given the care it deserves.
a 90 min vid, just great, cold drink, nibbles, and some good video watching. keep it up Mike :)
Great troubleshooting, with unexpected assembly programming!
During the first low level formatting, the system reported 2 diskette drives, when only one floppy disk drive was connected.
Thank goodness for modern pc's.
Looking great, sir!
You must be the most patient man in the world 😊
Don't forget to park the head before turning off. 😁 Great old XT.
36:10 for the Super Glue related problem, try to use some glass fiber cloth and epoxy resin. Becomes really strong really quick and is almost indestructible ^^
Your videos are the best part of my week/month..
Another Masterpiece by Mr. Mike!!!!!! If I could join at a higher level I would.
Floppy only Xts were common, Hard drives were a luxury. 1983 pricing was $2633 for a dual floppy, and $4995 for a single floppy with a 10meg HD.
Absolutely beautiful! And the computer looks awesome too
I love this videos, especially PCs from the 2000s, and of course, it's also nice to see Mike's arms 😂😂
What an adventure was it to watch this video !
Thanx for the trip down memory lane. I remember working on these back in the late 1980s. Your a more patient man that I working on this
Computer technology in its early days was hell, the modernization of the font is really cool. 👑
XTs arent that hard to setup.
This generation of PC was before my time, but there is still something satisfying about these kind of videos.
Wow! Over an hour long video! I was engrossed the whole time! Thank you for saving that system. I am not sure if I would have had the patience or knowledge to have done it! I love those old systems and cards that are just covered with chips, something about it looks so interesting to me! Cheers!
You did a gigantic job, I struggled with this work together with you. It was worth it, the effect is there. Greetings from Poland ! Zrobiłeś gigantyczną pracę , razem z tobą się męczyłem przy tej robocie . Opłacało się , efekt jest . Pozdrawiam z Polski !
Mike, I greatly admire your enthusiasm. I'm inspired by your knowledge and passion for vintage PCs. And of course, those well-sculpted biceps are quite impressive.
Such a cute fella!
Nice job Mike. Your patience and persistence is inspiring.
That's why I keep an FK-2001 in my collection. It's switchable between XT and AT modes.
A hour and a half of Miketech? Holy shit, hell yes! And on one of the all-time classic PCs.
Loving the longer video, thanks!
Nice to see the XT eventually became a happy computer by the end of the video. I was hoping you'd get to work on something like this - this is more or less the exact system I develop games for!
You could add a half height floppy for the blank hole!
Mike next time you have to use superglue on something, add some baking soda powder to the glue right after you apply it to the plastic you're trying to glue together. It will almost immediately dry the glue and make it WAY stronger than original. Chemistry. Yay.
I also had one of these during my early childhood. I fondly remember finding it in the attic during a move in probably '94 and booting her back up for some fun. My dad and I had started putting systems together around then, and we were both in shock how 'slow' it was, and even before win95 it seemed archaic to my 11 year old self. I was too young at the time my dad got it to realize how important it was, but I do remember using it with him in the late 80s. There's gotta be some polaroids somewhere... You really bring me back though, thanks Mike!
As a kid we had an XT clone with dual floppy drives, because it had a Hard Card slotted internally... This still makes similar sense today if you slot in any sort of XT-IDE-CF Card solution.
Awesome video man! Nice to see some restoration
My first thought with the two floppy drives was that maybe it'd had a Hard Card installed, they were pretty common as upgrades or replacements.
OK Mike, i'm triggered big time also. 4 of these machines were purchased at my work back in the day at the start of 'computerization' of our office. Ah, those were the days so much fun !!
Wow that brings back a ton of memories, I had the same as my first PC when I was 5. Mine had a custom clam shell case that I haven't seen since.
wow Mike, can't wait to see all the videos with the new systems! so awesome! great long video, love it! that red toggle switch should've been in the front, it's so cool, that red color. imagine a modern case with this switch and based on this old design
man what a journey! awesome video as always!
this was an amazing rehab I love the section with the o-scope
I just watched to the end and I am impressed by your patience, great knowledge and passion.
Greetings from Poland and I look forward to more videos.
The bane of a permanent fix is a good enough temporary fix. May your "temporary" fix last forever!
im hype to see this
I remember that ST-225, I had one in my old DTK 286, though it was a 40 MB sub-model. Good times!
Awesome video, Mike! 😁
Omg! I know you are beyond excited to find this system. I remember this from your childhood days. This really takes me back.
I always loved watching you work on computers. The 486 you built when you were 8 was fantastic.
Your excitement working on this system is fantastic. My chest puffs up with pride for your skills!! This is why I love watching your videos!!! So glad you found this system!
Fantastic video and restoration! Made my day and brought me so many memories. Thanks for sharing! Stay safe and God Bless.
Superglue mixed with baking soda sets like concrete, just a tip going forward.
Finally some smoke lol
Really enjoyed this one. Thanks.
Allthough I started my computer life with an Amstrad CPC 6128 my first PC system has been a 80286 Desktop and after that a 80386 tower. I loved those bulky PCs and still remember their weight. Thanks for this video 😊
Going old school with that XT machine. Great reasteration. 👍
Indeed the fiirst pc remains special in ones heart. My first pc was an Apricot Computer 386 SX 16 mhz, with 1 mb ram and 40 mb hdd. I remember having so much fun playing dos games on it. Man, you are soo lucky to play at 6 years old with such an iconic pc. Good video, Mike!
Great reasteration!
Always enjoy these videos. As someone with a few older pcs, socket 7, slot 1, socket 5. Its a great learning experience and helps me get a little closer to figuring out what mines doing!
great video i love retro
Super job! Really enjoyable video 💪🏼
AMD processors were very common on the XT (worldwide chip shortages and rationing by manufacturers with set limits for Europe, Asia and North America). The memory card with RTC and serial/parallel ports is third party. With the XT, it apparently wasn't widely known you could install a jumper on the motherboard and replace the first two banks of 64k chips with 256k chips to get 640k on the motherboard. The slot closest to the processor is really designed as a dedicated RS-232 slot, since it has a dedicated hardware interrupt that is enabled by a jumper on an IBM serial card. Indeed that is a genuine IBM CGA card, depending on the brand those tantalum capacitors would make pink or gray smoke. Source - I worked in a factory building these (and lots more) from 1981 to 1987.
The most common manufacturing defect was reversed polarity of those tantalum capacitors, so they came out with those 3 pin to prevent it (this means you have one of the last revision boards). A vise will crimp those cables just fine. The cable and connectors are readily available, I really recommend not reusing them. The -5v rail is used by the monochrome adapter and 2400 baud internal modem cards. Many clone power supplies left it out and it caused no end of consternation when the 2400 baud modems came out and used it. The dip switches on the motherboard and the AST card must both be set correctly. If no memory count, first thing I would check is the first bank of memory.
Easy to forget, "format c: /s" installs the boot sector, otherwise use sys c:.
really enjoyed this one
the psychedelic patterns on the capture looks like the capture card is trying to lock on to a color carrier and then decides "nah" and switches to monochrome, which is also why it sharpens up so much despite being composite.
Good TIP for MFM / old scsi / RLL drives.
Never directly connect them to a controller.
Best to do is connect them to a PSU connector only.. And let them run for some time.
See if the motor start spinning and doesnt make strange noises.
If the bearing is stuck, probably due old grease that hardened.(sometimes bearing could also be worn, then drive isnt worth saving, or you have the ability to replace the bearing without damaging the drive). I mostly put the drive on the back and let it run for some time to free it up.
If the motor wont start.. Dont let the drive attached to the current..(power it OFF) Otherwise something can gets very hot and burning out the motor or the complete drive.
I would just open the lit. But let on stay on the drive (dont remove completely( Lift it about 1cm (dont know it in Inch).
Dont touch the platter on top or buttom, only little bit the side..
And see if you can get the spindle get loose.
Re-tightned the lit.. And see if power get the drive spinning again.
Let it spin for a while so the drive also turning free.
If you know for sure the drive runs fine, then you can connect / attach it to a controller en see if you can get the drive working.
IF you open up the whole lit, always you a can of airsol, and blow out all dust bunnys.. So the platter is SUPER CLEAN.
Before attach the lit again.. Hold it above the drive (very low) keep blowing out the dust, and that attach the lit back again.
If you did it good, the drive should still work.
Great Diagnostics on such an old pc.
Best video ever. Well done, tedious work, but well ✔️ done.
Warms my heart that you have reverence for the 5150/5160. Keep up the good work.
Great video and cool machine. I remember navigating through a machine very similar to this as a kid as well. Oh and maybe more Van opening scenes to :-)
Great vid Mike 👍🏻 Remember these from my old College days. Luckily had 20MB HDD.
I sold my ST-225 with the controller on which it was formatted. I still have my ST-125 but I may sell it as well. I have an ST-4096 in my 5150 currently.
Dynamic configuration is one of the nicest features on WDXT controllers as it allows drives to be used which would otherwise not be supported. It stores the drive configuration onto the first cylinder of the drive during low-level formatting.
I have been looking forward to this one!! :D
I've never had one of these, but they've always held my interest!!
Really good video. Reminded me when I was fixing my 2 Atari drives, and fixing my 1998 Aptiva floppy. Thank you
Great👍
The hard drive spindle motor needing help to start makes me long for a world with crank-starter hard drives...
Ineffable restore video!!! Mine was an Atari 800XL I learned BASIC on.
The 8-bit Guy worked for AST.
mezmerizing, outstanding work! thank you a lot for this video, I learned a lot - I got such a case kinda AT style (with normales 5,25 drive bays), with the large power switch, was a 286 computer once, but now its an 166 mmx multi os time machine! I love it! thank you again!
More ewaste haul? There’s going to be more nice videos coming I guess :). That’s a nice system, hopefully you can get that ST-412 going, the fact it seeks fine and doesn’t sound like there’s atrocious damage inside probably means there’s a decent chance at least.
L4 on those floppy drives is a common failure point. It blew on mine as well.
It is part of a power supply filter circuit, but you can probably get away with installing a jumper wire in its place.
I seem to recall that after fixing L4 a tantalum capacitor next to it also failed, so I'd replace that at the same time.
Hi Mike, Another Good Video Sir, After going through some rediscovered Vintage Hardware, I noticed at: 20:58 the little 8-Bit Card above the larger Card, I’ve got 2 of those plus I found 2 x MFM Drives, 2 x 5 & a quarter inch Floppy Drives along with Disks, Also Motherboard’s, 286, 386 & 486 etc and all sorts of different ISA Cards & a few PCI, I’d left it all in my Brothers Loft in the late 90’s & forgot all about it, I will be uploading a Video to my Channel at some point soon hopefully! 🙂🇬🇧
