Identifying Model M keyboards
« on: Fri, 29 October 2010, 20:22:44 »
How do you identify these keyboards, did a quick google search and found nothing.

I heard the early model m's are the most sought out.  

What years are these two.  thanks!

Both of those are 1990s. However, they were both made for numerous years. Both will be either Lexmark, Unicomp (or perhaps IBM Greenock?) depending on age and some other factors.

The sticker has the date of manufacture on it.


thank you for the quick reply!

Is there a website I can read like a wiki or something so I can be more knowledgeable about model m's.  I'm looking to understand why early model m's are more sought out, etc.

I also paid about $30 shipped each for those keyboards.(one with a missing ctrl cap)  Was it a good buy?

Well, there's always the IBM Wiki here at geekhack!  Try that, probably has more information that you could find anywhere else.

Yeah, Wikipedia should link to that!

They've clearly been lurking because they changed the "quality declined" thing and now all of a sudden have a whole section about how good 42H drainage channels are!


definitely!

I hate wikipedia, there can't be any original reserach there, but it's ok to make wiki here and then copy info from here to Wikipedia... It's quite messed up system...

Anyway, might start to collect all the model numbers somewhere. And then make compilation about which relates to which, for those non-US layouts...

Here I thought the post-'92 Model M's were more coveted, because of the drainage channels and all that, which is why I thought I was lucky to get a '92 for pretty dang cheap.

As a rule of thumb, if it has "G" as the third character, it's a Lexmark keyboard with a non-detachable cable that may or may not have two-part keycaps. That 42H1296 is probably a variation of the 42H1292. Both would be mid-to-late 90s.

IBM produced so many different part numbers that keeping track of them would cause your head to explode. The thing is that most of them were identical. Thus, the IBM wiki only keeps track of particularly common and/or noteworthy part numbers.

Do you have these keyboards?

i've tried a 91' IBM and a 95' Lexmark and there was barely any difference

i would prefer the earlier model personally because i like the detachable cable - if it gets broken it's easier to replace - and i don't think the drainage channels are that great since if you do spill something and it gets in between the overlay you're still going to have to open up the backplate and clean inbetween the overlay (like i had to) but the difference isn't as much as some people make out

Do they click when you press button down? Difference between buckling-spring and rubber dome should be extremely obvious. Feeling is totaly different and they are much much more noisy...
