Model M's with Non Standard Caps
« on: Tue, 29 September 2015, 09:29:46 »
Hi Everyone,

I came across these two 1391401 Model M's today with different caps and was curious to see if anyone knows anything about their specific purpose. Thanks in advance for any insight!

Blue/Green Caps





Red Text Caps

Wow, that looks pretty cool. The legends kinda suggest something related to finance, I think.

Very cool finds.

I'm just guessing here, but I think the top has to do with either stock trading or accounting from reading the legends.

The lower one is a bigger mystery though.  There's 'load form' and 'init ptr' which makes me think they were used in a capacity where there was a printer.  But I could be totally wrong and ptr could be 'pointer' and it might have been used on a specific statistics program.

I wish there was a place where the people that used these back in the day could just say--'oh yeah, I used that when I worked at such and such'.  That would clear up the mystery really quick.

Thanks! I'm sure there was someone who used these keyboards day-in and day-out of their life for work and I would love to hear what they were used for exactly.

Does anyone know who would have manufactured the caps for these M's back in the day? Was it IBM or some third party that sold custom computers to different industries? So many questions! haha
