The Good, the Bad and the Less Than Totally Inspired (IBM PS/2 Model 50Z Overview/Demonstration)

[@dkehrerproductions]

Its very cool that you post these videos .A lot of people just don`t have the appreciation for the older technology . I started having a interest in using and working on computers in the early 90s so seeing computers like this from the time is kind of cool . I have a mix of computers in my music studio that I use Ranging from 30 year old Commodores ,Pentium 1s IIs and IIIs as well as multicore modern computers . I still find it more of a kick and a challenge to work with and use the old stuff .

[@Betamaster64]

A nice guy posted one of these on Craigslist in mint condition with all the peripherals and Windows 3.1 installed for FREE. I was fortunate enough to get there first....Now, I buy and resell computers as a small business, but I just can't bring myself to sell this one. It's definitely a great machine.

[@marccaselle8108]

I would like to sell old computers but I don't have money coming in and don't have the money or places to get old computers that don't cost 200 to 500 dollars on eBay.

[@newtekie1]

"The IBM PS/2 series does toolless right. You just need this special tool." Wait...what?!?

[@jansirkia3809]

I found mine in a dumpster almost seventeen years ago. I still have it. To get it running, I just had to replace the cmos battery and download the reference disk image still available from IBM 23 years after. That is true commitment to the customer, I'd think?

[@savantskie]

I used to deal with these on a regular basis. The trick to working with the power supplies, is to unplug them and then turn the power supply ON. This will dissipate any power left in the rather large capacitors in this behemoth of a power supply back then. I often wondered how dangerous it could be working on one of those until I forgot to do just what I said, and accidentally touched the power switch to a metal peice of the chassis. Needless to say, it welded itself to the chassis with what power was left in the capacitors. It was a big shock, and scared the bejesus out of me. Never forgot to do it again!

[@shana_dmr]

+SmerrillS Reviews It's pretty important to remember about this, considering on most switched mode power supplies there is cap that is charged to full rectified mains voltage (around 170 V in US and 320 V in Europe).

[@savantskie]

+kroplaaaa I know. this is why I suggested unplugging it and then turning it back on to disperse whatever charge was left.

[@MoTown44240]

Nice video. I have 2 PS/2 IBM Model 57 that were given to me. Fortunately, a friend gave me his set of W3.11 disks as I don't know what became of my original set of diskettes and any version of Windows after that seems to have found its way to the garbage pail. Your voice is pleasing to listen to and I have yet to hear any uhs or ands which so many others non-chalantly inject into their videos. Have a great day.

[@snsm6730]

THANK YOU !! Great to see someone is taking time to preserve this stuff for the future. You just never know when you might need to use older gear and this stuff lasts longer then the cheap flimsy stuff that passes for computer gear these days 8-)

[@Kenny-bw2cz]

It's amazing how you learned all these details about these machines. I have a ps/2 tower that need the Dallas battery hack to get it to work again

[@stephenbianchi7141]

No idea why I clicked this video but you seem very knowledgeable and made me want an old computer... It would look nice with my retro gaming consoles. Nice machine and video.

[@grlg2]

Hi, very nice presentation and commentary. Good to see some old tech being preserved, keep up the good work. Most younger people now days do not appreciate older equipment and see last years model as old. I love some of the comments: Sofa of an automobile, tantrum capacitors. Cheers.

[@trucker9652]

Old computers are a great hobby. Cheaper then old cars and guns. Allot of great games and it is still fun to play flight simulater 1.0 on an 8086 or 286. Found a version of space invaders that uses 5k of mem and works on 8088 hardware. I always liked the ps/2 just from the way it is designed. I once got word 6.0 working on an original 50z with the 287 and 16 meg ram, max for the 286. Biggest pain for the ps/2 is when the battery dies you need to use the reference disks on startup.

[@josh6715]

Trucker are yes flight simulator love that game

[@awhooley]

Totally agree... I got myself an old Toshiba 8088 desktop pc on ebay a while back, and man its the best fun ever..

[@Adamsnadler214]

What is the best classic flight sim

[@marccaselle8108]

Yes old computers are fun. As long as you have between 200 dollars and 500 dollars to spend your all good 🙂

[@trucker9652]

@@marccaselle8108 Back in the 90's companies would get in trouble for throwing them in dumpsters. Back then I can across the Obsolete computer museum and thought it might be a fun hobby. My wife finnaly made me get rid of my collection which had some nice pieces, even some 8080 stuff. Bought a Tandy 4 for 50 bucks and they guy hands me a box full of software also.

[@bjmgraphics617]

It was a solid 286 that set the PS/2 standard until USB finally killed it in the turn of the century. I still have a PS/2 converter plug for my mouse. I don't miss cleaning the mouse ball and the inside rollers. I loved the upgrade expansion card options like VGA, OPL 3 sound or an early wavetable card, scanner, and SCSI HD. I also remember installing over a dozen 3 1/2 floppies for one game. I owned a Tandy 1000 TX that had a VGA card, memory expanded card, and an Adlib sound card. I played Wing Commander which ran about 30 fps for an 8 MHz PC. My old friend had an Epson PC with 12 MHz cpu and Wing Commander really flew well over 30 fps.

[@archechme]

Your videos are great. You seem to know what you're talking about and it's great hearing somebody talk about something with a lot of passion. Anyway, thanks for the videos.

[@bobfdowd]

My first computer, bought myself...Model 50z, with a 30 mb Hard Drive. $3358.08 for the CPU, Keyboard, Mouse, Color Monitor and IBM Dot Matrix printer. Unlike computers today, this mating lasted from 1988 through 1999, when I sold it...working..to a guy who wanted his kids to have a trash machine to bang on. Wish I still had it... I do still have the mouse in the video...

[@thewunderhase]

One of this was my first own Computer. An 286 with 20MB HDD :3 I love the harddrive sound… thanks for this vid.

I have worked a lot on these line of IBM machines, loved them so much.. The tower models where true gems.

[@mythril4]

When I was in middle school, I fixed up a huge stack of these and gave them away to a bunch of students. Think I went through about 80 of them. I remember installing Windows 3.1 on them all, it actually run on them just fine. I tried a diskette install of Windows 95 on one, it was slow to install and slow to use. If I remember right, the Windows 95 diskette install was like 38 disks long.

[@chloedevereaux1801]

15 3.5in disc's actually.just sold one on ebay,sealed with original c.o.a for £197..... :)

[@Mattf121]

Depends on the version of Windows 95. The earlier versions were on around 15 floppies, later versions had more disks.

[@choppergirl]

My dad had 8 of these given to him as junk. He junked all 8 of them as hopelessly obsolete in the late 90's... all except the mice, Model M keyboards, and power cables. I pulled out all 8 of the kyboards the other day from a stack of 300 keyboards and tested them all out today and all 8 work... typing on one now. The Keyboards and perhaps the little tiny color VGA monitors were the only things about these systems that were not total junk. He didn't get the monitors though, except I remember seeing maybe one. The Model M keyboards are sweet as h3ll though...

[@lordsyn86]

Old vintage computers are what laid the path for new age computers. These machines are what my childhood was made of. I love these vintage machines.

[@OmegaWolf747]

Ah, the beautiful nostalgia of the PS/2. I learned touch typing on a machine just like this 31 years ago in tenth grade. Great memories.

[@RetroTalk]

Great video again uxwbill. Glad I subscribed to your channel as your videos are informative and fun. I must say despite the capacitor issue that looks to be a very nice example of an IBM PS/2 and congratulations on the winning bid. Your the reason I have started making my own computer related videos and such. Keep up the good work! /a loyal fan

[@kirbyyasha]

Very sexy system, I have never seen a set of IBM Keys with their PC. I've seen people either drill them out, or live with it unlocked. Same with many later 90's Pentium-era desktops with the keyboard lockout. Seeing this makes me want to one day make more videos showcasing my computers.

[@CoolDudeClem]

It's crazy how hen this stuff was new, I thought that nothing could ever come along and top that technology, but now it can be easily emulated in things such as DOSBox. I have to admit I don't find old PCs very interesting now, but I still watch and enjoy. However when it comes to old computers such as old Amigas, Spectrums and others like that, I find it fascinating!

[@johanandersson8689]

Thank you for the video! I got a computer similar to this one for christmas in 1996, and DAMN! This disappointment i felt cannot be described with words. I was 12 years old and my relatives thought they had made a good deal. I know they were fooled by the seller and that they did not fuck me intentionally, but at the time it was this or nothing. It had a 386SX processor and VGA graphics, so it could not even run Simcity 2000. How about installing a sound card or a CD-ROM drive? Yeah, right... With MCA and lack of IDE support, I was pretty much fucked. In 1997, my friends were playing Quake on their Pentium based systems with Voodoo GPU:s at LAN parties while I was staring at the cursor in Microsoft Word 6.0.

[@camouflage81]

I had a monochrome 8088 at that time, so I'd have been jelaous of you! LOL

[@JazzBuff23]

I feel so sorry for you I could cry. BRAT!

That old computer looks very interesting and it is interesting the way that you take the big meter peace out of it!!!

[@lxPhilxl]

I love the modular design of this chassis, kind of like the designers were playing with lego. It certainly made for quick repairs in the office where the IT guys would appear like a pit crew at the race track. Good vid!

[@nobodycares85]

The "magic Smoke" you mentioned brought me a great laugh one time when I told somebody that the electronic components ran on smoke and that person actually believed me and did not realize the joke.

[@metfan]

Keep making videos about old computers we love them

[@zorilla0]

It's amazing how tolerant some hardware is of blown or missing caps. I recapped a power supply on an LCD monitor once and decided to test it without realizing I had totally forgotten to put in a replacement cap in one spot. It turned on like nothing was wrong. Who knows, maybe it was in parallel with another that was doing enough of the work to operate normally.

[@lburbo23]

I bought one of these a couple of weeks ago after snagging it off Ebay for a decent price. It was in near-perfect cosmetic condition save for a paint scratches. Once it arrived I was, suffice to say, pretty angry and disappointed when I opened the box to discover the seller didn't bother to pad the bottom of the package. The entire front bezel was smashed to pieces, but miraculously everything else survived, and works. It even had the special tool still attached!

[@uxwbill]

The same thing has happened to me. I bought an 8570-E61 to replace one I lost in a basement flood and the seller didn't even bother to pad it. That smashed the front end right off the front of it and broke up the floppy drive mechanism. Luckily, back then I still had some spare floppy drives in working condition and the top cover/front panel from my flood damaged machine. So I made a good one out of two.

[@lburbo23]

I did exactly the same thing. Sadly this seller also neglected to pad the four corners of the case. the left side is broken at the base by the front PC speaker, and by the rear expansion slot. The bezel is not entirely a loss, but it is damaged on the left side. After this double-fiasco I've come to loathe Fedex, and sellers who do not understand the value of these machines. The bright side of it all is that this other unit comes with a Kingston SX-Now! 386SX-33 upgrade chip.

[@vwestlife]

I had two of those tantalums blow up in my IBM 5150 PC, but they're just power rail filtering caps, so they're not critical. My friend in high school had a Model 60 with the SLC/Now upgrade, and this seems a bit more sluggish than I remember it being. As nice as it sounds, that 30 MB hard drive is probably the performance bottleneck.

[@IfYouLikeGoodIdeas]

I finally got around to cleaning up my own PS/2 Model 50Z today, and let's just say, I got to experience "tantrum capacitors" firsthand. That very same cap, C23, while it didn't turn itself into a rocket like yours did, it did blow its top off and send flaming bits of itself skating across the inside of the computer. It really is rather dread-inducing watching this play out through the computer's front grille. Fortunately, after dismantling the system and clipping the remains of the blown cap off the board, the system did come back to life (though I should probably still source a replacement cap). Now it's bombing out on 161 and 163 errors (I assume due to the dead and subsequently removed CMOS battery), and it refuses to boot the reference disk (both the original and a downloaded one), so that's next on my list.

[@trancerobot]

My old high school were using these as late as 2004, and probably later. They might still be there.

[@johnhpalmer6098]

Wow, this takes me back. I once had a 386SX20, though from Packard Bell, and it was a hand me down from my late father. He'd bought it new in 1991, running DOS 4 and has all of 2MB of memory installed in it. I got it in 1994 with Windows 3.1 and 4MB of RAM. I've come a long way since then and now run a core i7 bad assed Dell desktop system these days.

[@thedungeondelver]

IBM: nobody will ever design a retention clip as silly as these! Intel: Hold my beer

[@yblademoor]

I acquired a PS/2 model 70 a while ago. I do appreciate the modular design. I was also fortunate enough to have gotten an IBM VGA monitor and a 8514/A adapter card in the purchase. :)

[@uxwbill]

On the proper monitor, the 8514 video mode is quite nice. (Even on the "proper" 8514 and 8515 monitors, you can still see the flicker, but for me at least, it is tolerable. And 256 color high resolution video is nice on a 286 class machine. I used mine in a Model 50Z. Should set it up again and do a video, while I still can.)

[@yblademoor]

@@uxwbill Yeah, I haven't gotten around to get my PS/2 up and running yet. I'm aware that the refresh rate is nothing home to write about nowadays, but if i throw a LCD CGA monitor at it, it should hide the gflickering. Been wrestling with a Gateway 2000 4DX2-66V... I really kinda want to throw Windows 3.1 at the PS/2 just for kicks since the 8514 is well known for being one of the early fixed function windows accelerators. :)

[@Seegalgalguntijak]

These systems are virtually indestructible! In the late 90s, I've been given 2 PS/2 systems which I later traded in for a (then huge) hard drive of several hundred Megabytes. They were in lower cases, had 2 FD drives and were equipped with 8086 or 8088 CPUs. With one of them, I slid a screwdriver over the connectors of the RAM card while it was on. It was a sparkly experience, and of course crashed. Turning it off and back on again brought it back to life though. Try doing that with DDR3-RAM! ;)

[@francistheodorecatte]

I'm glad I found my Model 80 (8580-111 converted to a 311) in a closet in NYS office building. It was missing the mouse, keyboard and monitor, as well as many of the expansion card slot covers. Judging by the fact that AIX was loaded onto it, those empty expansion slots were probably filled with serial cards.

[@TechGuyCharlie]

Its beautiful!!! Great video..!!

I have a some vintage Macs and some DEC Alpha systems in my collection. Always look forward to your car, audio, and PC vids! :-)

[@gwreijman]

Nice computer. The slow speed of the system can also be caused by drivespace that is running in this system, drivespace was like doublespace a drive compression tool to "double" the storage in a system. And the strange dos prompt can be found in the autoexec.bat file. You can change it in prompt $p$g for the standard c:\> prompt.

[@quonomonna8126]

i had this computer when i was 11 and absolutely loved it

Yeah I know. I have worked on a few of those cars with the L05. They are good solid engines. The LT1 engine actually came out in 1992 for the C4 Corvette, however the LT1s in the 94-96 Caprices/Impala SS's are detuned by about 40 horsepower.

[@NBH45304]

Wow nice find. I forgot about these machines. We had PS/2 systems in our AG room at school back in 1993 or 1994. They had dual floppies on them. We had to load Dos 3.1 before playing any games or programs on them.At one time I was pretty good at tinkering with these "tempermenal machines" as our teacher called them. But that knowledge has been replaced with other useless info. Thanks for sharing.

[@supermasterPIK]

I remember buying a 486/75 Mhz Packard Bell computer back in 97 (yes, it seems strange for today that a 486 lasted till that year), but Pentium based PC were at leasr $2500 or $3000. For that machine was available a Pentium Overdrive CPU, but thet upgrade kits were at least 70% of machine price. later came Celeron and machines were cheaper.

[@Lukeno52]

22 mpg for a car of that age, size and with that engine, plus the fact that US gallons are smaller, makes that very impressive!

[@ncrdisabled]

I loved those old machines Back when I was working for a big power company and I was a power line tech . The sent me to the IBM school to get advanced IBM repair from IBM 30 to 95 . The best part most of the time no tools to work on them. The worst part was adding memory to one of those memory cards . I also work on the AS 400 system. Back then added memory was used for Microsoft word and Qemm . Remember the LIM?

[@MrNotorius5500]

The old tub style caprices truly were known to achieve pretty good fuel economy especially when you're talking about the ones equipped with the TBI 350 V8 engine and such. However, when those shocks go bad, you might find yourself getting seasick (yeah, thats right) on the open road because that car had a horrible tendancy to bounce all over the place.

[@lhuser]

It's there for a reason, and to be on the safest side, replacing it would be a god thing, in order to avoid instability, crashes or who know what else!

[@dukenukem5768]

It is not "tool-less" - the plastic lever for the button clips is a tool, and unlike a common screwdriver is not easily replaced if lost. I had a PS/2 at work. One day I stayed late and got the HDD out, took it home, put it in my home PC, and installed OS/2 as a dual boot alongside the DOS/Windows. Those button clips and other "clip-together" features were a PITA; the plastic lever thing was not around (the IT support guys had confiscated them?). OTOH my home PC was "cottage industry built", all screws and therefore far easier to tinker with.

[@PerKristian]

Just bought one of these with the original 80286. It has the monitor, keyboard and a box og software manuals. Its currently at a friends place in another city while i’m trying to find a way of safely shipping it (this is In Norway, and i don’t want to use the postal service). It is untested, but i got the whole package for 500NOK ($50)! If you have aby tips for best practise when doing a first startup of a system like this, i would gladly welcome them!

[@uxwbill]

Have a reference disk handy. You may need a replacement clock/CMOS battery. (In these it is a camera battery, the CR-P2.) The floppy drive may need some electronic help and to be cleaned. The lack of a shutter means they can collect dust and random objects. There are surface mounted electrolytic capacitors on some of the drives and these fail often. You might experience (as I did) a tantalum capacitor failing shorted and being blown apart.

[@squirlmy]

@@uxwbill I haven't watched the whole video (does the video itself qualify as vintage?) , but in discussing transistors with vintage Apple Mac collectors: note the Macs do not have tantalums, but that means the transistors can silently leak over the years degrading the mainboard and causing damage without the owners knowing it. Some Mac collectors purposefully replace transistors with tantalums, exactly because these will fail loudly, and inform the (knowledgeable) user right away. This is arguably a better case for the user, as long as they understand what exactly is happening. I guess it's a personal preference in the end, but... think twice before replacing tantalums with "regulars". It might be bad for the computer's long term survival!

[@NJRoadfan]

Hey, my 50z did have the keys... and I still have them! I'm surprised he didn't spring for a MCMaster card, it would be MUCH faster since the RAM would be running with 32-bit data width and at CPU speed. Basically makes it a Model 56 since it only has a 16-bit bus. Is that machine running 3.1 in 386 Enhanced Mode?

[@OlegKostoglatov]

The last time I saw a three legged capacitor type thing it was a vertical integrator from a TV set. I'm not sure what the story is behind these tantalums having three legs, maybe it has two caps in one package?

[@brunoshow124]

i had a few old ibm ps/2 model 70's that were shot, but they still ran. the same thing happened with the cap, but mine shot a small flame out. there was nothing left of the cap.

[@SvartaSnuten]

Me and my dad was going to start our old Aptiva family computer that had been standing cold and sad in the basement collecting dust and dead bugs, so we took it up, vacuumed it, and plugged it in. Guess what it did... blew up! I was right behind it to put the cable in the PSU so i was looking right into it and dad turned it on right away so i didn't have time to crawl away to safety and let me tell ya'... that flash didn't help my already bad eyesight... must have been one of those capacitors

[@krist0sh]

Hey! I just wondered about something. While I was cleaning up at work, I found a box full of old software. In there was, OS/2 2.1 (with all manuals and stuff that came with) a OS/2 for Windows 3.1 (same contents) and a Windows 95 Release Preview (you guessed it, with all the manuals) Are this things rare to find, and harder and harder to find?

[@Lachlant1984]

Is there any particular reason why you are so fascinated by the PS/2/Compaq DeskPro business PC's in particular? I mean in the late 80s/90s these computer would have been considered high performance for business, but they weren't the only game in town, and good quality generic PC clone would have also served the job, but I'd be curious to know your particular interest in the PS/2, is it the tooless case design? It the Micro Channel Architecture? What is it?

[@Adamsnadler214]

These are just beautiful machines, they did so much wrong and right and are so boring they are exotic

[@JKproductions184]

I think one could argue that the snap-remover could be classified as a "tool", which would make this model a little bit less than tool-less. Still a neat find!

[@eznix]

My thought exactly. I hope uxwbill was being sarcastic when calling this design "tool less." Even if the tool is included in the case, it cannot be said to be tool less.

[@Kenny-bw2cz]

This is a beauty!

[@stonent]

Probably a bit sluggish because the drive is compressed (judging by the error that Smartdrv couldn't load because Drvspace was running)

[@johncoleman2474]

Today I just found 2 working PS/2s. One has a 386DX-20 with a Coprocessor!!! The other is a DX-20 only. They both have maxed out ram and one has an XGA-2 graphics card. The other has a SCSI FRU controller with 30-pin simm cache.. $10 well spent!

[@rickhunter6242]

This is AWESOME!...What's the line (in autoexec.bat or config.sys) for the Kingston upgrade to enable the cache during startup as seen here?

[@uxwbill]

You will need the actual Kingston-supplied cache enabler program. As best I remember, it's known as ktccache.exe and I know it can be found online.

[@rickhunter6242]

Great thanks! found it. What's the size of the double sided simm on board?

[@uxwbill]

2MB, which is also the maximum supported.

[@rickhunter6242]

I see, good to know thanks!... This is definitely one of my top tube channels as you are full of knowledge when it comes to these machines. I also have a model 50Z, my unit has a 2-8 memory expansion MCA card that is currently populated with 4X 512kb 85ns simms (4 slots/2MB). Do you happen to know if any faster sticks may work on these cards or do they only take certain low speeds?

Have you ever thought of ever making a KZbin playlist of all your PS/2 videos?

I love IBM computers, especially their laptops.

So I found a Model 50z a few weeks back in someone's trash along with the IBM monitor and four Model M keyboards (only one cable). I only just got around to working on it, and it's been complaining about needing a reference disk. I found an image online and put in onto a floppy, but it still won't work for some reason. Any advice?
