Pertec keyboard

This is a keyboard made by Pertec. It was listed in the Deskthority forum topic titled (at the time of writing) 60% poly case, Geekcable USB A to C, Akko Purple, MX Red + more posted by CL4P-TP (“claptrap”), but after it sold, all details of it were erased including the image gallery on Imgur (located at https://imgur.com/a/lGCA7Um when it still existed).

As this is the only known keyboard in the world that used Elec-Trol Datakeys reed switches, the photographs are preserved below. Curiously, these are not the normal cruciform stem, but rather an adapter stem in the manner of (and conceivably compatible with that of) Micro Switch KB.

The switch model number appears to be KA1004-0001. The PCB itself is marked with identifying code 150079-05. This could be the keyboard model, but it appears to just be the PCB artwork number. The IC dates are from 1973, which is contemporary with the 1970 Datakeys advertisement.
