I was cleaning up the estate of an MIT prof, and came across some Philco transistors with odd markings that I suspect were made for IBM. Generally, TI made the transistors for IBM, but I have seen a few SMS cards with Philcos on them. Philco transistors look a bit like bullets - about 1/2 inch long, and maybe 3/16 inch diameter, metal with a rounded top. Often the leads are insulated, as the spacing is very tight. I do not have any SMS cards with Philco transistors. Does anyone (CHM 1401 crowd?) have any they could inspect for me? I would like to know the numbers printed on the case. -- Will
