doctorq (or anyone else):
The CVPPC I have is a Phase 5 model (not a DCE one thankfully). It should work -- I used it until I upgraded my A4000 with the Mediator, so it was working when I last pulled it from the Amiga. It still has its VGA connector but no cable, as I only had one (the other one broke a long time ago), which I sold along with my BVision.
Still, having said that it is possible that after the time it's been in the box, it has stopped working - I cannot verify it, unfortunately.
I have no idea of how much this one would be worth... any suggestions?
