Hi Dick,

boards
No, the board is about 1/16" think but it has thick WW sockets. The 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".
with lots of connector contacts on both sides, and lots
of 16-pin DIP layouts
on the boards? Are there functional names stamped on the boards, like Buffer
A, Adder, ... things like that?
You got 'em in the Orlando area, right?
I got them in Melbourne. About 60 miles from Orlando. Sounds like you have a GOOD idea
of what they are.

Subject: id these weird ics?
Today I picked up a wire wrap card with some
strange ICs. They're 16 pin
dips with white ceramic bodies and gold lids and
legs. They have the numbers
7552-1C and 7350 on them. I believe the 7350 is a date code. There are other
ICs on the card and they're all date coded to 1973. There's also a note on the
board that says that it was modified on 7/25/74.
There's also a trademark symbol on the ICs that looks like a black box
with a
lower case "i" showing through in gold. I don't think I've ever seen
this trademark before, does anyone know what company it's for? Anyone know
what the ICs might be?
Joe
