Thanks to those who replied, I have got my card to work!
The clue was working out which jumper pins were expecting video and 14M
clock in to them. Once I got that I could see the video signals coming out
PL1. I still need to make up a special cable to link the card to my BBC
micro's microvitec monitor because the monitor has got the wrong socket in
the back, but that will not be a problem.
If anyone out there also has one of these adapter cards and wants to know
what jumpers I have set etc. then let me know.
