Ethan,
I wrote the post about the TI 9900 processor cards. What are the
dimensions of the cards, and how many pins? I have two ram boards that may
be similar to yours, perhaps a little older based on the RAM chip numbers
you list below (assuming smaller number means older). I have the details
of my TI 9900-related stuff on
http://vintagecomputer.net/ti/TI-990-101/readme.txt.
OK... I don't have an exact count, but my cards have _two_ sets of
edge fingers, each set *well* over 44 pins, perhaps as many as 100
each. From what I've been reading, I don't think these are from a TI
990... I would have to guess they are from something older, as the
RAMs are 4kbits, and from what I can tell, the TI 900 is from later
than the 4kbit RAM era.
I guess the next step is to get some pictures online and go from there.
Thanks for the pointers to the TI resources.
