Haha! made a discovery whilst cleaning up my desk... the trackball unit has two joystick ports on the back of it

I've only just bought the CDTV, so I've never used the trackball before.
All I need is a SVHS cable to plug it in to CDTV and I'm set

Well, that and a keyboard now:)
Anybody got a CDTV keyboard for sale/for trade for my A4000 keyboard?

Failing that, how to make an adapter for the A4000 keyboard?
