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.

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!

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.

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!

As in previous video, the galvanic spray is a real game changer in metal restoration. Very appreciated! Merry Xmas!

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 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.

Nice restoration Tony. Merry Christmas 🎄❤

Congratulations!!! Fantastic work! Always blown away just fantastic

Thanks again for the great video, have a wonderful Christmas! Looking forward for next year's content

beautiful work. thanks for the great restoration.

This is absolutely brilliant, such an attention to the detail, it came out gorgeous! Merry Xmas!

Excellent video, thanks!

A very nice restoration. Thanks for all your content this year and have a lovely Christmas and a safe and prosperous New Year

Great video Tony and again got many flashbacks of my old job. Merry Christmas my friend and keep up the good work.

Good job! Very entertaining video! Thank you and Merry Christmas 🎉

Great work Tony!

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.

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.

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... ;)

Nice work Tony, the PS2 looks great. Have a great Christmas and New Year, catch you again in 2024.

Enjoyed the video!

Great job.

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! ^_^

Wow that power supply looks amazing. Great work!

Really really nice work with the rust. It looked like a ton of work but it looked great.

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.

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

I used to repair these regularly back in the '90s. The biggest two failures were the power supply and 50ns time delay module.

Che meraviglia Buon natale! ❤

That IBM drive diagnostic unironically sounds cool. There's no way it wasn't intentionally made to sound like music.

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.

Something about the IBM Dance reminds me of the Ducktales Theme - am I the only one?

You could add some extra circuitry to generate the index pulses to replace the function of the faculty chip.

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. 😊

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.

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!!

Neato!

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.

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 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.

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.

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.

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

Try broken chip on other drive since soldering (heating) may fix it sometimes 😂

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.

Just because a thing is unnecessary doesn't mean it's not worth doing. I might put that on a (large) t-shirt.

I would have stopped at the board swap!

Nice to know that ps/2 is Y2K compatible

Dang why all that rust.Love your work.

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.

My IBM Model 57 runs fine.

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.
