What is the UK version of the 1390131?

[Chyros]

Simple question really, does anyone know the part number of the UK equivalent of the '0131 (1st gen non-XT square-badge rainbow-plate)? I find it hard to find any sources Oo .

That's the equivalent of the 1391401 .

When did Greenock come online?

Is there a UK parallel to the 1390120?

Yes, that should be the 1389969, which I added to wikipedia a while ago (it's the UK-layout XT model). There are a whole bunch of completely conflicting statements on Model M part numbers between our wiki and wikipedia though. If the 0120 is the US XT version, it's the UK counterpart of that.

I don't know when Greenock came online, but it must've been extremely early as my early-production 1388032 (the one built with prototype parts) should be from there.

According to the below video, it appears that Greenock came online in 1954, so a long long time ago:

I can't find the 1389969, but the XT is nothing like the Model M.

The 1380363 in the wiki looks exactly like the 1390120 because it has no LEDs.

The 1388032 looks like an industrial version of the 1390131 (with LEDs).

From my personal experience, the only visible difference between 1390120 and 1390131 are the LEDs.

All the keyboards in the wiki are ANSI, are some of yours ISO?

I don't mean Model F XT, I mean the XT-compatible Model M. It didn't have lock lights because the XT protocol doesn't support them.

This should be a 1389969. I spotted one on eBay a few weeks ago, it came with a 5150 system and it had the label still on it, so it was easy to identify properly.



I have never seen the UK counterpart to the 0131 though, which is obviously AT and does have the lock lights. It should exist, but I've never seen a trace of it. Hopefully someone here has one .

The 1386303 is quite different from the 0120; it's a terminal keyboard (it precedes the AT connector) and has a different numpad.

The 1388032 precedes the 0131 so technically it's the other way around but yeah, the 1388032 is the industrial 0131.

All the UK model Ms I have are 1406. I also found a 1394324 a while ago, as well as a batch of ten Unicomp 58.036 rubber dome Model Ms.

I have never owned a 1390120, does it have an XT/AT or other DIP switch?

I'm not sure tbh. What I've read almost suggests the board is somehow simultaneously XT compatible, but I don't see how that would work.

It probably won't help, here's an old thread on a 1390131:

Found it, ironically on Geekhack :p .

I figured if the 1391406 is the UK version of the 1391401, maybe the UK version of the 1390131 is called 1390136. And apparently that was the case!

Here's the post showing it:

I'll add it to the list on wikipedia soon.

I have an original IBM XT with the original boxes and manuals and it came with a 1390120 keyboard and it worked natively with the XT computer.

I was also able to connect the 1390120 with a 5-pin DIN to ps/2 adapter and a ps/2 to USB converter and use it my modern 2016 computers without needing to flip any physical external or internal DIP switches. My guess is that the internal keyboard controller in 1390120 is capable of auto-switching between XT/AT keyboard codes.

Cool stuff, good to know! Updated the wikipedia page accordingly.

Great job on editing the wikipedia page.. I've been watching that wikipedia page since it was originally created in 2004 and have been happy to see more and more user-submitted content and history added to the page.
