I was somewhat shocked to find out that my TopMax
EPROM programmer doesn't handle the vintage 2708
1k x 8 EPROM. A very interesting little EPROM
the 2708. It requires +5, -5, and 12v.
Anyway, any advice out there for working with
these old little beasties? I'd like to first
read one, but eventually program them. Or
maybe I should program the 2716 and substitute
them (with appropriate bent-up pins)? Maybe,
too, I could read them after telling my TopMax
it is a 2716 and (again) bending up a few pins,
or maybe using a pulled-pin socket.
The 2708's are found in an S100 EPROM card
in my newly acquired Altair.
