I found this stuff in a pile of scrap boards last week.
<http://www.classiccmp.org/hp/Interdata/> I'm not sure who made them since
I can't find a manufacturer's name on them but a number of the boards have
a tag on them that says "Passed Interdata Processor Test" so perhaps they
were made by Interdata. Does anyone know anything about Interdata or know
who made these? The names on the files are the name that's etched into the
boards and I'm sure that they're some kind of computer boards. The dates
on the ICs range from 1973 to early 1976.

Intedata was a computer mfg. They made a series of machines (I vaguely
remember a model 4.) They were somewhat like a 360/30, I seem to recall.
Their chief claim to fame was that they were designed to be
microprogrammable. I think one of the implementations used a set of wires
strung through a series of W-shaped transformers. Passing the wire through 1
side resulted in a 0, and the other side gave a 1. Thus it was possible to
change the microprogram and thus extend the instruction set of the computer.

Interdata was a fairly important minicomputer maker in the early 1970s,
but faded by the end of the decade. They were purchased by Perkin-Elmer,
and some Interdata 7s are tagged as Perkin-Elmers. There is still a user
group called Interchange, that keeps the few survivors going.
