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
