Sooo... Does anyone have a spare D780C or am I going to have to pull
apart my
Toshiba HX-10 (MSX) and, er... "borrow" the
CPU?
Alternatively a ZiLOG Z80 would be fine. The original CPU has a 1984 date
code, but it's in a socket so I guess it's been replaced already. A
replacement from 1982-1986 would be nice (82xx to 86xx date code), but
not
essential.
I have a spare D780C with a 1983 date code. Mail me off-list if you want
it.
I think the original may have been socketed. It was common to socket
thingss like MPUs, ROMs, etc, in those days, but the 1984 date code sounds
late -- I think the Ace came out in 1982.
