I have a Teletype Model 33 with a UCC-39. I would like to run it with Mike Douglas’s RS-232 adapter so I can control it with my PC.

But I don’t know anything about the UCC-39. My other Model 33 worked with a UCC-6 board and Mike’s serial adapter.

Does anyone know what the difference is and have a schematic?

Thanks!
