Help identifying

[Bootsy]

Hello,
Hoping someone can help identify specifics about these. We bought them at a local store for $2 each (for making computer art). They have a Texas Instrument symbol on them, but not sure anything beyond that. Any help would be appreciated.
Thanks!

They look like they were from a very, very old green screen DOS based computer. I had a HP Vectra that had parts like that, but back then I didn't know much about computers so I couldn't tell you what those are. My guess is RAM.

You could try Googling the model/serial numbers and adding Texas Instruments to your query.

It's an old Canon Canola 1210. Like this http://www.oldcalculatormuseum.com/canonl1210.html

Or at least the part that I can read the PCB code for (X61-7604-07)

Looked closer at some of the other ones with partial codes visible, they are just different Canon calculator models circa ~1970

Amazing you needed that much circuitry back then for a simple calculator. About 20 years latter you could find calculator watches.
