IBM industrial Model M video tour

[@shivkishanupadhyaya5766]

I never realized how much I loved vintage keyboards until I found this channel

[@jonasgafert]

Neither do I.

[@antoinefdu]

Chyrosran22, I'm glad there are people like you to take care of such beauties. I wouldn't want it to be left to rot in an attic somewhere.

[@sambalsamurai9672]

5:13 no body has EVER talked so thouroughly about bolts in any industry ever before :D

[@0M9H4X_Neckbeard]

13:00 definitely makes it look like a prototype, that appears to be an EEPROM chip with a protective sticker over the UV-hole. I don't know much about Model Ms but on Arcade machine PCBs those were only used for prototyping since they are erasable, and were repaced by conventional ROM chip on production boards. if you need to know more about electronics or PCBs I suggest asking KZbinr lukemorse1 he's an american living in japan and also a PCB god

[@Chyrosran22]

+0M9H4X Cool cheers, I'll give that a go :) .

[@wazazaby]

What an incredible channel

[@Chyrosran22]

Thank you :) .

[@lemmmmmmmmm]

I'm a little late to the party here and I'm not sure if you've figured it out yet, but I wonder if this was thrown together for a trade show of sorts? Maybe they were still prototyping this board and had to debut it at a trade show, so they took one of the prototypes, painted it, scavenged spare parts to make it all work and then put it out at the trade show for potential buyers to see and consider buying for their factories.

[@Pauleh123]

I'm pretty sure that the Lexmark PCB is different from the regular IBM PCB, so that may be a bad comparison. Very interesting tho. Lovely find!

[@Chyrosran22]

It most certainly is, I've seen tons of different M PCBs over time. This one was easily the biggest.

[@woodyofp8574]

Maybe somebody working at IBM put it together one piece at a time, getting the smaller parts home in their lunch box, and the larger parts in their friend's mobile home.

[@lovesnakeden]

*_"Pick up some milk... Now, where is that? Here it is!"_* lol Your voice reminds me of The Postal 2 Dude. :")

[@turbo3400]

The legs on the oscillator are likely there to shield it from the soldering heat, assuming they used a dip/wave soldering process.

[@rockerito7030]

I enjoyed this video a lot! That's a sexy keyboard. So envious, it makes my beloved '95 Model M (on which I'm typing this) look meh. Great video!

[@paulie-g]

The reason you can't find an oscillator on the Lexmark PCB is that it isn't there (in one piece). There will be a resonator plus some caps etc that together form an oscillator circuit. An oscillator is a higher cost, all-in-one component with the oscillator circuit inside of it and is typically used when higher precision or much higher frequency is required. You will typically find higher quality cuts of resonators in an oscillator for example.

[@Ambassador_Kobi]

I worked on these keyboards, there were also models with a trackpoint integrated between the keys.

[@Chyrosran22]

+Jurgen Kobierczynski Ah yeah, that was the Model M13 :) .

[@gavincurtis]

The "newer" PCB has an oscillator too. It's the 3 pinned blue jellybean looking part at the lower right of the Lexmark PCB, just under the chip at the edge of the circuit board. Ceramic resonator. The chip itself on the original board with the tape is probably a UV erasable programmable microcontroller. Since this was a custom keyboard of low production number, they opted to use the expensive ceramic reprogrammable windowed part instead of bulk mask Rom programmed plastic encapsulated IC. That empty space without parts could be for data acquisition/signal conditioning if the unit had a track point nub perhaps?

[@greyareaRK1]

This remains my idea of keyboardness. I had a knock-off of this WAY back. Loud but solid.

[@laserhawk64]

On the smaller, later circuit board that you show, the timekeeping part is not a crystal but a ceramic resonator... I don't know much about them, but I know they're far less accurate and usually a three-pin part. Yours is the blue blob at Y1.

[@wobbled9819]

I'm wondering if someone put this together from spare parts? That'd explain the different keycaps, and the different LED overlay sticker for Numlock, scroll lock, caps lock. Black IBM badges were also available to buy from unicomp some time back so it's entirely possible the guy took a very old AT Model M and painted it grey and stuck an industrial badge on there. Not to mention the identification / date badge is missing so that could've been removed to prevent people knowing that it isn't really industrial. Who knows? Coming back to this video cos I find this particular one so damn interesting. Either it's a strange prototype that IBM made or someone did one heck of a good keyboard mod. Subbed to you btw, you seem to share my keyboard obsession! Just scored an IBM Model F 84 key AT keyboard today :)

[@Chyrosran22]

Nice, and thanks! I think it's rather unlikely someone threw it together from spare parts, considering these parts are extremely rare on production keyboards. The paint job is ridiculously good if it's not by IBM, although early industrials have been documented to be painted rather than made out of grey plastic.

[@wobbled9819]

Chyrosran22 Interesting board nonetheless, how did you acquire it?

[@Chyrosran22]

I got it at a recycling centre for about £0.50 :) .

[@wobbled9819]

Chyrosran22 And I paid $1000 for mine, consider yourself the luckiest guy alive. Jfc.

[@Chyrosran22]

Oh wow xD .

[@jackfrasiercomedy5942]

That cable is also very satisfying!

[@MD-wq6on]

I sure miss typing on those beast keyboards. They were tanks!!!

[@y11971alex]

That yellow connector looks like it's from a PC/AT Model F... I've found that connector in both of my ATs.

[@Chyrosran22]

Interesting, I didn't know that! Someone did mention that the yellow connectors are only used on the very earliest Ms, so it'd make sense. Apparently they're quite nice because they don't corrode at all or something.

[@y11971alex]

The grounding cable though, that is also present on my 1390120 from mid-'86.

[@ghostything]

Ah, frankenboards. Used to have an (apparently) ISO-UK Model M with a few mismatched keycaps, and the board came bundled with a previous owner's Soarer's converter kit. The #/tilde key never worked though. Turns out that the board was actually ANSI and a previous custodian had gone to the effort of swapping the ANSI Enter's stabiliser hole with the spring from the backslash key, so the board appeared to be ISO and all the keys clicked, but the contact for that one key was in the wrong place. Weird.

[@gencreeper6476]

Something tells me this was rebuilt somehow. I know Unicomp has the 2 piece keys. Strangest thing to me is the insert and delete key symbols (they look similar to two keys on the beam spring keyboard you reviewed? Wonder if this was partially handmade either from junk as a cost saving method or to perform a specific strange function. One thing I'm curious about is if the top panel is also painted

[@Chyrosran22]

It appears to be made up of parts they had lying around at the time, which definitely suggests it's a pre-production sample of some sort.

[@lordadamfirst]

This is a thing of beauty

[@RubySapior]

OMG how did you get your hands on a 1388032! You cant even find them on the market anymore. I was only able to find 1390120 which is like $300+ in decent condition. Ive been looking for a 1386303 board, and my search is still ongoing :)

[@Falkenroth1]

Just bought one that came with a 5170 computer and 5153 monitor. Same model with black square badge.

[@ColtonBlumhagen]

Suspicious of no label. I almost think it could be a 1390131 that's been painted. (Has the same style badge as Industrials) But if real it's a good find.

[@Chyrosran22]

+Colton Blumhagen The badge on the '0131 is black on white though, not white on black ;) .

[@HudsonGTV]

@@Chyrosran22 I know this is an old video, but couldn't the badge have been replaced with a black badge?

[@Chyrosran22]

@@HudsonGTV Nothing is impossible, but it's extremely unlikely; the internals are WAY too old to fit a 0131. Really only very few keyboards, let alone models, came with these internals; even other 1388032's probably wouldn't've come with these parts.

[@FlightTheatreAlberto]

I have an industrial M! About 10 years newer though, lol. Mine also has the rainbow bolts aswell. Maybe thats an industrial thing

[@GLAORleader]

Looks like some kind of prototype

[@zenithseeker7]

Under the sticker is probably a UV window for an EPROM . The thing must really have been hand assembled and/or been some sort of prototype...

[@Chyrosran22]

Yes, both of those are my guess as well.

[@gmcenroe]

I have a silicon graphics keyboard for my old Indigo 2 workstation. I am also a chemist, we used to use these workstations for modeling. I have it packed away in the garage, can't seem to part with it, the entire computer. Now you have my curiosity as to what kind of keyboard they used.

[@Chyrosran22]

If it's an SGI "granite" keyboard it's a pretty good catch :) .

[@gmcenroe]

This IBM Industrial Model M has a very similar look, same key layout at my granite SGI. They both lack the "window" keys on bottom row. SGI has a PS/2 connector and alps white keyswitches. They can be found on ebay for $30-$50. At the moment I am interested in the Topre switch keyboards, with the thonk sound vs. the clicky sound of the cherry switches. I am still deciding between Realforce 87U or 104U or Leopold FC660C models. The alps switches on SGI are somewhere in between in sound, lower pitched pleasant sound.

[@gmcenroe]

I went into the garage and dug out the old SGI granite keyboard that I had stored with the SGI Indigo 2, hooked it up to my PC to try it out after I cleaned it up a bit. It is a very nice keyboard but a little underweighted but with a decent sound. I tried to buy a keycap puller from the local computer store, but they did not have one. When I get one online I will determine what kind of ALPS switch is in the beast.

[@MisakaMikotoDesu]

Mine has an oval logo on the left side. Neat.

[@DannyJP29]

I wish you could do a unicomp review but I know that's be hard since he have to buy it and then shipping

[@MisterCOM]

This is realy late Chyrosan but somebody pointed out that the legs on the oscillator are possibly there for protecting it from the heat of wave soldering so my question now is if it is wave soldered because if it isn't it might realy be a prototype if its hand soldered

[@sarreqteryx]

the large IC with the sticker is a Motorola microcontroller, though, I'm unable to find any detailed info on it. it's likely the keyboard's controller.

[@Xengrii]

Such a nice keyboard, I would love to have one myself. Can you tell me from where do you get so many mechanical keyboards in such a great condition? Where I live (Not in the US or any english speaking country) there are very very few old mechanical keyboards for sale, and if there is any, they are in horrible conditions. Thanks.

[@Chyrosran22]

I get most of them from recycling centres and the uni I work at. The ones I find tend to be either really clean or ultra dirty xD .

[@Xengrii]

I would love to be as lucky as you xd. I suppose I will be looking around more carefully and look for keyboards xd. By the way, I have an old blue ALPS keyboard but the switches are quite deteriorated and adding lubricant doesn't work at all, is there a way to fix it?

[@Chyrosran22]

Ah, the big curse that haunts Alps switches; their sensitivity. People have experimented with lubes but the results aren't great. The best thing is to clean them thoroughly. The only great results people have reported is from cleaning them in an ultrasonic bath.

[@davebw123]

Not sure who is the saddest. You for making these videos or me spending over an hour and half so far watching them. Haha. Great videos though! Subscribed.

Yes, they do. Specially the older ones. I have recently bought a quite pristine '94 model (blue logo). But it feels and even sounds different from the very older ones. I've never seen this model before. A true relic. You must be proud :-)

[@Chyrosran22]

Frederique Rijsdijk Thanks, yes I am ^^ .Believe it or not, this was the first keyboard I found at one of the centres I started visiting - if I'd started going there a week or so later, it might've been lost forever!

[@Chyrosran22]

+Coach Four at the moment. I sell most of them off. I would've sold off the Lexmark if it worked :p .

Where do you sell them and where do you suggest buying them from? I'm currently looking to get one for my keyboard collection. I currently have 2x Model F's (1x XT 1x AT). I absolutely adore the Model M sound.

[@connormason7907]

I have found some data pertaining to this specific keyboard. It appears that this keyboard is from an IBM 7552 industrial computer. www.9999hp.net/keyboard/temp/

[@Chyrosran22]

Heh, interesting. That's actually the first ISO version I've seen of the 1388. Being that this one is also from the UK, and in fact assembled from what appears to be leftovers, it might be from before they put in the ISO layout. Nice find, cheers!

[@connormason7907]

They made an 84 key industrial M as well! Now all you have to do is get your hands on that beast.

[@andljoy]

A ceramic chip hmm. That chip is porb worth more than most modern keyboards :P

[@Chyrosran22]

+Andrew Joy What chip is that? =o

[@vaclav_mach]

+Chyrosran22 It's an EPROM memory or a microcontroller with EPROM memory (I haven't found exactly this one, but it's something like "TMS7742JDL"). The sticker covers a window, under it is the memory itself - don't remove the sticker, the UV light could erase it -> making keyboard unusable...

[@campampates]

3:09 the IBM lettering on the badge is uneven...that shit would make go insane

[@Chyrosran22]

The lettering is even, but the badge is ever so slightly misaligned, and the effect is exacerbated by the angle. I hadn't even noticed it before tbh.

[@MrSteveenn]

Looks to me like it's just a frankenboard that someone put together and painted to look like an Industrial Model M

[@Chyrosran22]

+Austin Pratt Nope, definitely not that, the badge alone is a dead giveaway that it's authentic.

[@MrSteveenn]

+Chyrosran22 The LED badge being from a German Model M and the board itself being US ANSI is what throws me off the most, not to mention that it looks like a regular early Model M that has been painted. I have seen some "homemade" Industrial Model Ms before, and I'm pretty sure Unicomp had some Industrial badges a few years ago. I'm not saying it's not authentic, but there are some irregularities that make it seem very off.

[@Chyrosran22]

+Austin Pratt Indeed, it appears to have been pieced together from extremely early parts. Hence the suspicion that it might be a prototype, although we're not sure yet.
