Thee IC in the picture is in a Smith Corona Messenger Module. These Modules are used to allow printing from certain SCM typewriters from old computers like the Apple ][ and early IBM/PC clones. Any computer that had a serial port.
It is a simple circuit board and a good first project for reverse engineering. These Modules can be found from time to time, but when found on Ebay, they want $100+ for them.
I understand this first one will likely cost me at least that to replicate, but it is more about the learning process and experience. I have a larger project planned, and this seemed like a good place to start, something useful, but more simple.
Anyway, I have identified every other part/component on the board. This one eludes me. So, I either need to be able to find one, or at least find enough information about it that I can replicate its function with a Pi Pico or other small board. Please let me know if you know anything about this IC or where to get one. The obvious
is that it was made by AMD in 1982. But the numbers don't seem to come back to anything useful.
Thank you.
