Dude, this is the kind of content we need more of. Not only did you fix it, but you went the extra mile to confirm your diagnosis and then an extra light-year to meticulously restore that case. Thanks for sharing this labour-of-love with us.
Thank you for your kind words! It would have been simpler to walk for a light-year! :D But it's done! And it looks great! Thanks for watching!
Yep
That power switch! I remember such a power switch acting like a child lock because it was too difficult for me to flip it on my dad's 286. Otherwise, an amazing restoration of this old machine! Congrats on a fantastic job!
ahah good point! Who knows if it was intentional! Thank you for watching!
Awesome video! Glad the PS/2 drive worked out. Such a shame though the HDD is an issue. I had 3 drives and all 3 of them had the same exact problem.
Although there is a solid-state option now, using the proprietary planar connection...
@THEtechknight thanks and indeed. @IBM_Museum interesting. Where do I find out more? Still, I do need the squeaky noise. :D
Well done Tony, wonderful to see the PS/2 restored and working again. I love the idea of reusing dead hard drives with an Arduino. That may actually be the only way to make my Model 50 sound like the 1990s again :) Merry Christmas!
It's taken so much time!!! So happy to be able to move it to my living room and not to see that motherboard moving from place to place in the workshop! I shall give it a go before I forget. I have the driver somewhere, I need to see if the stepper motor is compatible with that. Thank you!
@@tony359 The toughest ones are the most rewarding. Enjoy your Model 30 :)
As in previous video, the galvanic spray is a real game changer in metal restoration. Very appreciated!
Merry Xmas!
It is indeed, I kind of regretted using the metallic on the case!
Thanks for watching!
What a fantastic job! We had tons of these at my school and I had a chance to save some when they were done, but I didn't take them up on the offer. Really kicking myself now!
I can very much imagine! We had about 30 at my school, the idea that they all went to the landfill breaks my heart! I'd love to go back in time to save them all! :D
Thanks for watching!
I thought to myself "He's going to swap the chip isn't he...?", I can understand that.
Considering the state of the rust I think it came out really well, and nice idea on controlling the stepper motor.
Finally, thank you for making these videos I really enjoy them, Merry Christmas.
Yes I am happy with the outcome even though I have to admit that the metal case is completely enclosed by the plastic one so... You can't really see it! :D Thanks for watching!
Excellent video, thanks!
Glad you enjoyed it, thank you!
beautiful work. thanks for the great restoration.
Thank you for watching!
Great work Tony!
Thank you!
Thanks again for the great video, have a wonderful Christmas! Looking forward for next year's content
Thank you for watching!
Nice restoration Tony. Merry Christmas 🎄❤
Thank you, Merry Christmas to you too!
Congratulations!!! Fantastic work! Always blown away just fantastic
Thank you so much for your kind words! :)
This is absolutely brilliant, such an attention to the detail, it came out gorgeous!
Merry Xmas!
Thank you so much! Happy Christmas!
A very nice restoration. Thanks for all your content this year and have a lovely Christmas and a safe and prosperous New Year
Thank you so much and see you next year! :)
Good job! Very entertaining video! Thank you and Merry Christmas 🎉
Merry Christmas to you too and thanks!
Great video Tony and again got many flashbacks of my old job. Merry Christmas my friend and keep up the good work.
Thank you and Merry Christmas to you too!
This brings back memories of a PS/2 Model 50z that I used to use back in the 1990's. I have always had a soft spot for the PS/2, it was the first PC that I ever used before I got my first custom built 386 running Windows 98 (not 98se just straight 98) in a monster of a full-tower case with 8Mb of RAM, a 20 Mb Hard Drive and a 5.25 inch floppy drive. I remember it was CGA and I "upgraded" it to CGA before finally going VGA. Happy days... ;)
Tell me about memories and PS/2! I started using PCs at school and they had PS/2 model 30s (8086!) - Thanks for watching!
@@tony359Back in the 1990's I was working for a security company and they were just going "computerized" as they phrased it back then. They had invested in the latest technology and had purchased a PS/2 Model 50z with a 20 Mb (yep, 20 mega_byte_) Hard Drive with tape drive backup. I was the only member on the crew that knew anything about computers so I was elected to get a database system up and running for them. The only software I had any knowledge of was Lotus 123. I managed to persuade them to get Lotus Elite which came with an integrated document writing program, a spreadsheet and most importantly database software. I spent a lot of time setting up that system for them and integrating the database of clients with the spreadsheet and word processor made invoicing and client tracking so much easier. It also played a mean game of Castle Wolfenstein after I upgraded to a Sound Blaster and a Trio64 Graphics Card, a bit chuggy on the graphics but still playable ;)
I just knew you would replace the chip 😅. Thanks again for a great video and love the First Contact part!
Merry Christmas and a healthy 2024.
Thank you for watching, Happy Christmas to you too! 🖖
Hi Tony, thanks for this amazing restoration. well appreciated your efforts for us to enjoy. Was a bit afraid for the chip swap instead of the pcb swap, but happy for you all work fine.
Oh I was scared too! But Curiosity won... :) Thanks for watching!
Enjoyed the video!
Thank you for watching!
Great job.
Thanks for watching!
Nice work Tony, the PS2 looks great. Have a great Christmas and New Year, catch you again in 2024.
Thank you and Merry Christmas to you too!
I bet the IBM PS/2 is very happy to be together again, looking good and being fully functioning. I sure was happy to see the machine being restored! Merry Christmas! ^_^
Oh yes, all the bits are happy to be back together in a nice and clean case! I am too, so happy to see this completed! Merry Christmas!
Really really nice work with the rust. It looked like a ton of work but it looked great.
Too much work :)
But it's amazing now!
Thank you!
Wow that power supply looks amazing. Great work!
It does, I wasn't expecting it to restore so well! Thank you!
Che meraviglia
Buon natale! ❤
Auguri! ❤
That was our first PC when I was a kid, I was disappointed in the early 90s when it wouldn't run Wolfenstein 3D. When we upgraded we gave it to my cousins and then they ended up biffing it when it died. Wish I had held on to it.
eheh those were the times where PCs would more or less double their performance at every generation change! Wolfenstein 3D was indeed taxing on those old systems! Thanks for watching!
I had to revive my IBM 486 too about 2 years ago, it was completely dead by itself, turned out the old capacitors in the power supply had leaked all over the PCB and killing it, also the mobo was dead for same reasons and contact issues. it took me some time but I re-cap everything and got it back to life again. it is very important to have in mind that old capacitors are starting to cause way more trouble today than most people understand. take care of your vintage stuff and happy Doscember, I just revived my old IBM Laptop that had a melting rubber coating all over the whole computer, what a job that was to get off
Capacitors are indeed a ticking bomb. I should power on my old stuff more regularly to make sure that still works! Well done with your IBM!
@@tony359 Thanks, I also have a Siemens Nixdorf Pentium 133 as a “daily” computer that I had to re-cap for the same reason as the IBM as the caps on the motherboard had started to leak a lot on this too. Fortunately I saw it pretty early so the electrolyte had not yet started to corrode anything. But it was a close call. This Siemens is stupid expensive to buy today. I was shocked when I looked it up that eBay want like 1000 dollars for it
some of those old ladies can be pretty expensive indeed! :)
@@tony359 That’s for sure. It’s a good thing I taken good care of my lovely Pentium all these years. I actually got it sooooo way back when it was more or less considered junk and I got it for free because I did a favor. I pretty much used it ever since when I want to play those speed sensitive games that only run well on a real Pentium
ahah I can understand! Some years ago I decided I wanted an old PC and thought "how much could they possibly cost", checked online and $$$$$$ or better £££££! I thought they were considered junk but no :)
My first PC was a 386 DX/25, no cache (!), only 2MB of RAM. Everything was SLOW! I also wanted a "proper" pentium machine to play those games again at proper speed! :)
I doubt i would go so far as taking a chip off of a working drive and replacing the faulty one with it but it does keep it as original as possible.
Seeing you use alot of elbow grease getting that metal cleaned up did make me a bit tired.
I have a sand blasting cabinet with different types of media available and it would take no time at all to get the rust off.
End result is looking amazing, great job.
I did consider the idea of sending the metal parts to a shop and have them sorted but it's not cheap so I reluctantly continued with the elbow grease! :) I don't have a sand blasting cabinet unfortunately! Thanks for watching!
I used to repair these regularly back in the '90s. The biggest two failures were the power supply and 50ns time delay module.
Oh interesting! I am actually surprised the PSU is still working. I've turned it on and off countless times! And it still has the original capacitors. Good tip about the 50ns delay module, I'll keep that in mind! Thank you!
@@tony359 Also the model 50z I think had the same delay line problem. Please bare in mind I did these almost 30 years ago so I may have mixed the 30 with the 50z but I think I'm right in what I put.
Hey Tony! What a great video and what a great coincidence... Just this morning I saved a BULL Micral 35F from the scrapyards... The machine has some scratches and a lot of dust, but looks complete and not broken at all... Sadly could not save the original keyboard and crt... Maybe I should do a video of it... I guess that would make for a great doscember video. 😊
Please! I am not familiar with the Bull! Thanks for saving that!
@@tony359 yeah neither was I, but this summer got a monitor with that brand and now I got a complete machine, will make a great pair. And they are not that common also, onoy found one thread on a french forum about it. Hopefully has something interesting inside. 😁
Hi Tony. What a mammoth project, Geordi La Forge would be proud😉👍
I did a 20MB IDE laptop HDD inside a IBM 5MB HDD, using a PIC, so an Arduino would do it easy.
Happy Christmas.
Mr. La Forge, one of my favourite characters of course!
ohhhh... that is another good idea! Install a modern HDD inside the IBM! How do you interface it though? The Model 30 is ESDI!
Happy Christmas!
@tony359
So I used a PIC, 32 pin ram sticks, some Op-Amps.
Mitsubishi made a one chip solution, but it was $180 last time I looked.
An Arduino should do it easy. Its only a matter of dealing with timing signals if I remember correctly.
I lost my workshop, equipment, computers, etc. to burglary and fire a few years ago. If I had my notes I would make a pcb.
That IBM drive diagnostic unironically sounds cool. There's no way it wasn't intentionally made to sound like music.
Good point, yes, that doesn't sound like a random movement! ahaha I can picture the IBM engineers discussing this in a meeting! Thanks for watching!
@@tony359 I honestly wonder how it sounds on different drives.
I think I tried it on the modern replacement in part 2, it's a bit quieter but still the "IBM Dance Party" sound :)
Really nice work,Tony. It almost looks like new 👍
Really good diagnosing on the floppy drive chip. But one question on that subject, how do you solder with your fingers crossed 🤣
Merry Christmas!!
Takes years of practice :) Thanks for watching!
You could add some extra circuitry to generate the index pulses to replace the function of the faculty chip.
Well yes but it's not straightforward. The index pulse is not there all the time, I do not know what the FDD controller is expecting. Definitely a project for someone who wants to tinker even more with that drive! Thanks for watching!
Something about the IBM Dance reminds me of the Ducktales Theme - am I the only one?
Had the exact same association.
ahah - it could well possibly be why I find it so cool! :)
Neato!
Thank you!
I would keep the non working drive and board as spare.. If you have to be able to go to a recycler, maybe you can find a damage drive with a good PCB on it and swap it around.
I wish I could go to a recycling place - in the UK it is not allowed to take trash from those places! One day I might be able to find an IC or a PCB indeed! I am definitely not throwing it away! Thanks for watching!
I thought I have seen someone who developed a board that could plug in to where the hard drive plugs in but you can use a compact flash card to load your hard drive data.
Yes, this has an XT-IDE, I showed it in a previous video. The OS is from the Compact Flash. I chose to load the game from the FDD as we fixed it in this episode so it felt more real :) Thanks for watching!
Loooove your videos! Have you tried phosphoric acid to remove rust? It works like a charm 😊 It`s the same acid as in Coca-Cola, which also works with rust in a way 😉 Keep the IBMs alive. Need to finish my ovn Model 30 now 😅
I watched some comparisons and turned out that Citric Acid is one of the best, even better than dedicated products. If you look closely in the video (I think) you can see I also tried some commercial rust remover but that didn't work because of the Chrome coating covering the rust. When I restored the Macintosh, that was simple metal and Citric Acid worked like a charm in an overnight. 100% of rust removed. And I can dispose of the fluid safely. But thanks for your input!
Good luck with your Model 30!
You want to finish the computer before the 2063 , i was in the state of ¿what? when i view the vulkan i understand. Yeah before the first contact , hahaha. I view startrek as well.
Live Long and Prosper :)
@@tony359 merry christmas and Live Longer and Prosper.
gotta be honest, i'm kind of surprised no ones come up with an adapter card to allow regular IDE drives in the older MCA systems. its not only been decades, but just about all the other older systems have some sort of interface cards or adapters to allow newer storage systems.
i wouldn't think the translation would be that hard with some of the newer chips. maybe a couple of rpi2040s to act as buffers and translators. shouldn't need a full blown fpga for this sort of thing, the original controllers are largely just regular ICs for both types, after all.
yours is a good point. However, an XT-IDE is a great option and it works with everything. With those drives, it would only be for a bunch of IBM models. But yes, weird that nobody has come up with something. It would keep the system more original indeed. Thanks for watching!
Just because a thing is unnecessary doesn't mean it's not worth doing. I might put that on a (large) t-shirt.
ahahah! I could use it as the new channel description! :) Thanks for the idea!
Are microchannel Compact Flash or SD card adapter cards available? That would be a good modern hard disk replacement. OR SCSI microchannel card and appropriate SCSI drive.
This is an ISA system. I have an XT-IDE in it, I could fit an IDE HDD. But it wouldn't have the squeaky noise I really want! My idea of controlling the heads with the arduino is a reality now! Check this out: ua-cam.com/video/R-9bGoGQm7s/v-deo.html
Try broken chip on other drive since soldering (heating) may fix it sometimes 😂
I did put it back but it didn't make it on the video. It actually made it a little worse. It was coming up with error 601 (Floppy error) more often than before. And still no formatting. So, no unfortunately! :) Thanks for watching!
Nice to know that ps/2 is Y2K compatible
I was shocked to see that!!! Unbelievable!
I would have stopped at the board swap!
eheh - I had a voice in my head saying "WHAT ARE YOU DOING!!!" :D
Imagine I'd killed them both...
But hey, it works! :)
Dang why all that rust.Love your work.
Thank you! That was a looooong project :)
does it have an ESDI imterface to connect HDD? I have some of theses drives, for which I have no use. If you're interested, let me know
Yes it's an ESDI drive! Are you in the UK? That is so kind of you! As much as those drives might not live for long, I'd love to have a working one! My email address is on my profile if you click of the description of the channel! Thank you!
I don't think it used to be chrome plating? Probably some other metal. Maybe bright nickel.
You can nickel plate steel and copper at home for a durable good looking conductive anti corrosive coating. Expect to pay about $15 at least for your nickel electrode, don't settle for suspicious product, or it'll bite you, it needs to be high purity. You'll find recipes. I suggest using citric acid, if you have it powdered, then make a concentrated solution and then dilute it about 2-fold. If you hate yourself like the rest of the Internet, you can use vinegar, but i tried and hated it, no way i would use that, the sheer stink. Please use as little salt as possible when preparing the initial solution, and just give it time, or you'll hate yourself as well. You can add some saccharine (artificial sweetener) as a brightening and hardening agent. The nickel plating does not really fill scratches and voids, the surface finish will only be as good as the underlying surface, if you want mirror finish, your base metal needs to already be polished to a super shine. I guess you can use copper plating as an intermediate step to help with that, but i haven't tried. You still need to buff the nickel plating just a little to make it brighter, but it's like seconds, barely anything, you don't want to burn through it.
Probably I was mistaken on the plating. Thank you for taking the time to share the process with me. I did check online and my issue is... space. I really don't have the space for containers with chemicals and water in my workshop. If I had the space, by all means. I know it might just be 1 or 2 large containers but I really haven't got the space for that either! I hope one day I might have the chance to go that route! Thanks again!
My IBM Model 57 runs fine.
Amazing!
@@tony359 The PC has two 2,88Mb Floppy drives and two 80 Mb SCSI Harddisk. The system has 16 Mb of Ram. It runs with MS-DOS v6.22
oh wow, the 2.88MB Floppy, I've never seen them in person!
@@tony359 The Floppy Drives were a present from a good friend. He collects also PC`s

You can rechrome the parts without having to paint them.
There are thousands of videos explaining how to do it in a very simple way.
If it's a real restoration, you should do it. If it's a simple repair and nothing more, what you did is fine.
Applying primer over the rust will help make it look good in the short term. But it doesn't solve the problem and will actually look worse in the medium-long term.
There is a clear difference between "repair" and "restoration". The plastic front doesn't look good.
I took a look some time ago, if not mistaken it implies quite a few chemicals, large containers where to submerge things... I don't have that amount of space I'm afraid. If I am mistaken and there is a simpler way, by all means please do point me to the right direction! Thanks for watching!
@@tony359 Doesn't require weird chemicals.
It does require that you have water at your disposal, a power source and a plastic box in which to put the piece to be restored. Nothing else.
If I remember right you need several containers where to tip the metalwork, some with chemicals, some with water. My workshop is small and quite cramped, I really cannot justify having extra containers just for one computer case. I struggle to wash PCBs as I need to find a container large enough, pour the liquid and then put it back in its container at the end, clean everything etc... It's just space constraints I'm afraid! But thanks for the idea!
@@tony359 Just only 1.
