Catronics CT100 RTTY TU

[jmh]

A long shot - does anyone have any info (preferably connector pinouts) for a Catronics CT100 RTTY TU? All I can find on the web is adverts from way back and no tech info. I am tracing the circuit out (slowly - dunno what's wrong with me it's just a bunch of discrete components and TTL chips!) - I'll figure it out but any info would be handy.

Thanks

Jeremy
