@Sirius - it is actually using a composite tapped from the entry to to the modulator, you can just see the connector in the photo. @Mark I used the FF in Graphic mode - they appear as quite grey more so than in the photo.

Just tried to experiment again and my VI board will no longer program with the PI key programmer - I assumed one of the chips (Like my 365 - I actually use an 80C95 in that) had gone marginal as it seems to step through with keypad but, My JMPecision with the V1 OS also seems to fail (even with the ols os flag in send14 set correctly) - maybe my PI0 is faulty! Argghhh
