Hi! Does anyone have the NEC uPD7220/GDC Design Manual?
I am looking for one as part of research on building a home
brew NEC 7220 video board.
Thanks and have a nice day!

I waited with a response, assuming that somebody has the manual
you are looking for. I am not 100% sure, but I might have that
manual. I am sure that I do have _a_ NEC 7220 GDC manual, and
I remember (15+ years ago) that I used that manual to write a
BASIC program to calculate register values based on the timing
parameters for the VDU. I don't remember if the manual contained
hardware info, it might. Next time I am in the old house, I will
search for the manual in the attic. Perhaps this weekend ...
