We can synthesise those with a Female edge connector and a nice Gold Plated
set of long fingers.
I agree - those connectors were beautiful and very useful in the days of
barely adequately buffered signals slapped onto a tin plated PCB edge

Here's the right-angle

Here's the IDC crimp cable end.
I assume this is the same company.
It may be a lead on where Kel-Am went to, . . .
But what Eric was asking about was a MALE card edge connector, and those
In his time at Apparat, floppy drives (5.25") had a 34 pin card edge
connector. If the drive was in a case, it meant opening the case every
time for connecting. So, Kel-Am made a MALE IDC 34 pin card edge
connector that could go on a short ribbon cable to a FEMALE IDC 34 pin
card edge connector to act as a short extension, to bring the connection
out of the case.
IDC MALE card edge is a R at RE connector type.
