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.
Hi
The usual NOS parts places. The NEC 7220 was made in enormous quantities
until fairly recently. There are a lot of stocks still remaining. During
the N8VEM ECB uPD7220 build and test no one had issues finding the chips. I
have about one tube's worth still.
All I am supplying is the PCB, the builders are making home brew computers
so they source the parts themselves. However as parts go the uPD7220 is not
a challenge. They are relatively plentiful NOS parts and inexpensive.
Thanks and have a nice day!
