Wow, that's quite a rare unit. Despite Videotex' great functionality
and good market penetration in other countries, it never gained much
acceptance in the US.
If memory serves, the TRS-80 Videotex terminal speaks the NAPLPS
(North American Presentation Level Protocol Syntax) protocol, which
won't be supported by many (if any) BBSs. It doesn't just move
characters back and forth; it's a remote graphics control protocol that
has quite advanced functionality, for the time.
I fear that it won't be a usable device today, unless someone puts
together a NAPLPS implementation. Which, now that this has come up,
sounds like a very appealing project.
Don't let anything bad happen to that terminal!
