BBC GE8/505 VDU Card circuit diagram required. Thinking of using this design as the basis (updated where required)for a homebrew Z80 machine. Would be very grateful to anybody that is able to assist or throw further light on the actual design.

I already have the BBC technical publication number 10425 overview Adobe PDF.

Also if you have a module, working or not would be interested in purchasing this from you.

Why don't you try emailing Richard Russell who designed it. I'm sure he will be able to help.
