The things really aren't bugs, Joe. They don't have legs. I know I've
thought of them as being alive at times, too, but they just might be from
Intersil. Are these on rather thick (1/8") nominally 8"x 9" wirewrap boards
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?

Dick

> 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.

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?
