Just finding someone with a SWTP TVT that they're trying to get operational would be sufficient. I also have the assembly instructions and schematics. I've long since discarded the (very heavily modified) main board. One of the first changes I recall doing was modifying it to display 16 lines of 64 characters and recognize a few more control characters. Interestingly, that last was mostly done with diodes and pullups instead of TTL gates. Shortly after that, I graduated to a Beehive Super Bee terminal. The serial board has an NE555 installed on it with a small trimpot as a baud rate generator. IIRC, 7497's were pretty hard to come by back then. I think I've got a taker, for the cards, BTW. Just need to get them into a small Priority Mail box and off to the PO.
