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 wiki. http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=VDU Thanks and have a nice day!
