Hi all,
Today I bought a SC/MP wirewrapped board. Does anyone know of a site with a
data sheet? My search came up with what is known as "SC/MP II", including a
description of a "MK14" project in Practical Electronics mag. In
particular, the chip on my board requires an unknown neg. voltage on pin
40, instead of +5 Volts on the later NMOS versions. The actual part No. is:
ISP-8A/500D
Thanks,
-Dave
