KIM-1 PCB Edge connectors

hanso — Sun, 07 Sep 2025 11:28:33 +0000

The KIM-1 needs 2 edge connectors.

The specifications are: card edge; PIN: 44; 3.96mm

When you search for those, the cheap ones pop up, Chinese made, look good. But they are no good, when you slide them one you need a lot of force, some even use a hammer!
The PCB is too thick for these connectors, you damage the edge fingers and can not change once connected.
DO NOT USE THEM for a KIM-1!

I had some luck, years ago I bough a lot, cable type (solder eyelets) from Conrad and they are perfect for the KIM-1.

I got hold a about 10 cm of MTU documents. Several I already had in PDF format, some not available yet.
I took the opportunity to scan/rescan/repair what I have online until now.
All documents in the MTU pages are now clean and higher quality, about 50 new PDFs.

Noteworthy are the new revised K-1008 September 1979 document and the now complete and revised K-1013 manuals and 2 versions of the CODOS V1 manual.
All the K-1002 documents, for KIM-1, SYM-1, AIM 65 and Commodore PET are new.
