Default Re: MK14 schematic revisions

I assume that even you would probably just buy one of the Czech VDU replica PCBs since that PCB doesn't really need to be improved - unless radically so, by adding onboard RAM mapped at 0200-> so it doesn't have to steal RAM from the system.

You don't actually need the char generator, the VDU will still give you a pixel graphics display without one. It obviously is needed if you want to display text.

It's just a question of deciding what line to take that VDU input to instead of MK14 'INT', and all agreeing on the same alternative.
