Earliest Known IBM Model M Keyboard?

So it seems that no one knows exactly when production of the Model M started, but the earliest examples seem to date back to 1985. The Model M 1386303 is the very first version of the Model M keyboard with examples seen online and here on Deskthority dating as early as June 1985. Also early industrial variants have been found dating back to 1985. Recently there was a very early Model M 1386303 that sold on eBay that dates back to May 7,1985. This particular board is ID# 00801, one of the first 1000 Model M's ever made. I bid on this, but apparently did not want it as badly as someone else.

Does anyone here have an earlier Model M or at least know of an earlier example?

Lovely. The really old ones just have so much more presence.

There are several known prototypes. I don't know if we have a date on them. The controller from my black-badge M is from week 51 or 52 of 1984, but that's of course not exactly the same.

I have a 1386303 from July 11th, 1985. It's 1 day away from my birth day which is nice.

As far as I know, the only Model Ms that have the possibility to be made in 1985 are 1386303s and 1388032s. Perhaps someone can add to this.

That May 5th 1985 board sold in a lot of boards about a month ago. My max bid on the auction was $150, I was taking an exam and it went for $152.50. The guy who bought those boards has made a pretty hefty profit now.

clickykeyboards might know of an older one, he has a pretty good database of Model Ms.

Yeah, in fact he has one of the prototypes as I recall.

Cool, thanks for the info. It likely would have sold at a loss had I not bid it way up at the end :lol: I've seen some shell out even more for early boards.

Here is the early model M that I have from August 1985.

This black frame model M keyboard has a female SDL connector and connects to natively to a IBM ps/2 computer via the SDL to ps/2 cable without the need for a converter. Also can work on computers with USB ports with ps/2 to USB converter or SDL to USB cable.

I also have a few other early 1386303 from 1985 with the 5-pin right-pin connector, but these model M variants were intended for non-PCs and can't be plugged in directly to an IBM ps/2 personal computer.

No offense here, but why don't you take 1386303s seriously? They are a Model M Enhanced keyboard, and they are the first ever Model #. Just because they aren't compatible with an IBM PS/2 (which nobody uses anymore anyway) doesn't mean they should be ignored. They can be easily used with a modern computer with the purchase of a converter.

I am going to have to side with taylorswiftttttt regarding the 1386303 Model M's. Even though this model can't be directly plugged into a PC, they are underrated in my opinion due to the outstanding build quality of this era.

I just wanted to share these spreadsheets from ClickyKeyboards which help to document early examples of Model M's. I am not sure if there is a similar database for other early M's like the 1390120.
