Anyone remember Kel-Am connectors?

[Eric Smith]

When I worked at Apparat around 1981, we used a lot of *male* IDC edge card
connectors. I've almost never seen any since, and I couldn't remember the
name of the vendor. I just found out that it was Kel-Am, but the internet
knows almost nothing about them.

Here's an example:
https://www.elliottelectronicsupply.com/connectors/card-edge/male-card-edge-idc-connector-34-position-kel-am-idc34m.html

That photo doesn't show the Kel-Am logo, which is just a stylized "KEL-AM".
There are some eBay auctions of the corresponding female connector (which
other vendors did make), some of which show the logo.

I wonder what happened to Kel-Am. Maybe they were acquired, maybe they went
under. It would be nice to find a copy of their catalog.

Speaking of which, it would also be nice to see some Robinson Nugent
connector catalogs from the late 1970s and early 1980s. I am especially
interested in seeing specs for their bottom-entry square-pin receptacles,
which I think _might_ be the ones used on Apple /// memory boards.
