Sorry Andrew, I wish I had it myself (just so I could sleep w/it under my pillow and brag). I do have several boards that use the 7220. If you want digital photos of any or all, I'd be happy (but something less then joyous) to provide them. They might provide the clues you need in the absence of a bona fide manual. Included in that list would be the NEC APC vid board, the NEC APC III, and probably a few others. --- On Wed, 6/10/09, Andrew Lynch <lynchaj at yahoo.com> wrote: > From: Andrew Lynch <lynchaj at yahoo.com> > Subject: NEC uPD7220/GDC Design Manual > To: cctalk at classiccmp.org > Date: Wednesday, June 10, 2009, 8:45 PM > Hi!
