Yes it is white all over - that can be seen in the tanks demo which was not very visible as it plays in inverse mode. I think I was just lucky that my Philips CRT has it offscreen - I will set up my MK14 and OV on my new Capture card if I get chance as I am sure that will show the artifact.

I know Karen was battling for Pins so not sure how we will be able to do the signalling - in other designs she has multiplexed some lines. RC0 the VDUOFF line seems like it might be crying out for that use - I am sure the other limitation that those and the PS lines are only sampled at frame start and maybe halfway could be utilized somehow?
