id these weird ics?

Well, the originals of some of the flight hardware that was done back then was wirewrapped using those thick ww panels. Those boards don't match the ones I've had lying about here, but the generation seems to be about the same. The ones I have use inserted pins rather than sockets. PC boards weren't considered reliable enough for space flight applications by some back in the '70's, but those sockets would never have made it into space. There are a couple of telecom companies located in that area that might be their originator. If you can find out anything about what Strobmerg Carlson was doing at their Lake Mary facility back then, if it even existed then, you might learn something. The boards I'm referring to are 1/8" thick, have about 122 contacts per side (top/bottom) but only one edge connector and yes, they may actually be 7"x8" rather than 8"x9", but they're clearly not the same. Mine are full of early (VERY early) 4000-series CMOS. I'd say you're looking at company stock numbers, which might be what you'd find in telecom equipment of the time, since they used the same parts in all their designs, but each PBX was wired differently, so considerable benefit was had from the stock-number-labelling. regards, Dick ----- Original Message ----- From: "Joe" <rigdonj(a)cfl.rr.com> To: <classiccmp(a)classiccmp.org> Sent: Friday, May 03, 2002 11:57 PM Subject: Re: id these weird ics? boards plastic part of the socket is about 3/8" thick. Actually they're not even DIP sockets just single rows of 25 sockets. There are two 25 position contacts placed end to end in 22 rows. The board has "Scanbe" etched into it with no other markings except Y/Y coordinates, Vcc, Gnd, a part number (11399), etc. It has only one connector, a 120 contact edge connector (60 contacts per side). The board measures 7" x 7 3/8". layouts Buffer have a GOOD idea of what they are. pin numbers other the seen
