Folks,
Does anyone have a NEC 7220 datasheet? I was just given two of these
chips (D7220AD, 1986 datecodes), and was interested in tinkering with
them. I have no earthly idea what the specs are, though, other than
"graphics controller".

It should be somewhere on the net. For programming info, google for the
programming manuals of the Rainbow Graphics Option (AA-AE36A-TV).
It is pretty detailed ...

Make sure you google for uPD7220 (that's the NEC prefix)

That was my mistake -- I kept searching for NEC 7220 and NEC D7220,
without the 'uC'. Couldn't find anything.
I have a copy of it now, thanks!

Used these once in a Nav product.
If you do not find data on Net, let me know.
Believe I still have the book.

I have a thick databook on this chip. It goes into all the
detailed programming of all the capabilities of the graphics
controller. Basically, the chip generates a raster video
image from some RAM and also implements graphics drawing
primitives in hardware.
