Gil, I'm not a collector. 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.
