They're black, about the size of (spit) a Windows CE box, I guess. It folds
open to reveal a keyboard with red, orange and burgundy-ish keys, and then a
single row 40?-character LCD with a "summary of commands" below that (in
Dutch, not much good to me). Does this ring any bells?
I'm particularly interested in figuring out how to talk to them *without*
having one unit on one end, like, say, have my workhorse C128 talk to them,
upload and download from them, etc.
I'm confident the baud rate would be low enough for the Commodore to handle
a transfer, but I'm not sure if a regular modem and the Text Tell could even
communicate (using the same modulation, etc.) I'm afraid I don't know much
about telecom standards, so the V.23 note went over my head. :-(
::Ob.pedantry: it would be Viewdata (comms channels), not teletext
::(broadcast).
*blush* :-)
