Super Early TI - TMC Ceramics

Found this board on the very very bottom of a huge gaylord of junk boards. Funny how the good stuff is always on the bottom. Thought you'd like. Regards OGM

No clue where it came from .. I'll leave that to the experts to determine

Of course it was on the bottom, if it was on top somebody would have already cherry-picked it! :lol:
Ok, so I'm guessing these are a calculator chip set?

Not to worry, just got lucky someone had actually catalogued the information or we still wouldn't know.

Phil, those IBM chips always look impressive with their aluminum caps. Can't say I've ever found anything interesting inside them though? The 30 pin SIMM would be from the mid 1980's I'd think, the DIMM is from 1993 based on the date code of the chips.

Phil, what are those memory sticks? prototypes?

 

[glorycloud]

Definitely looks like memory for the old IBM computer systems like
the early PS/1 or PS/2's or for some of the industrial PC's.

Cap, I really don't know... When I buy the mixed ram memory, I end up with with all kinds of "strange" sticks. I save them until I find if they're worth more selling them to collectors. I collect some myself, mainly to leave them to my 12 year old grandson.

Thanks, just curious really as when after you browse hundreds of pics of several thousand sticks of RAM drooling, and something weird pops up... its like, OOOH DIFFERENT!!!!
