PS, BTW there are still plenty of the ECB uPD7220 GDC board PCBs left. They
are readily adapted to almost any microcomputer/embedded/vintage type
system. They work well and interface to standard VGA monitors.
C: How much? And where are you getting all these 7220 chips from Andy? I think I have a
total of 3 in my possession, and all are likely soldered to something.
I have a lot of 7220 chips, pulled from Nokia VT220 compatible terminals
(Norsk Data ND-NOTIS terminals).
The terminal was based on a 80186 CPU with a NEC D7220 AD chip and eight
4464 dram (256 kbyte).
I haven't found any way to enable graphics mode on the terminals but I
haven't made a decent trial yet. The screen seems to be monochrome only,
no grey scale, so there seems to be plenty of memory for the graphics.
I can sell tested NEC chips, terminal boards (digital part) or complete
terminals to anyone interested. I always test the terminals before I
scrap them to see that the chips are good.
... I got 60 terminals left and it is still too much, I will save the 20
best of the lot, the rest is going to be scrapped unless I can find
someone who wants them.
