Sinclair Spectrum CTE/80 comms interface

[GeoffD]

Hi, I have one of these and have been wondering exactly how it works
and whether there are any online services that it could still be used
to connect to. I only ever used a BBC micro but acquired this somehow
in the 80's.

In fact, I'm selling it at the moment at

Please excuse this if you regard it solely as an ad but I thought you
might be interested.
