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.


On a related but different subject if anyone is interested, I just got the
N8VEM VDU board working (SY6545 based) and there are photos in the N8VEM


Thanks and have a nice day!
