On this location you can find the open hardware source of a RAM card made for the MTU bus

he RAMpager is a MTU banked RAM expansion for the KIM-1: the board supports up to 1MB (that’s three orders of magnitude above more than the original 1152 bytes!) of memory and maps it to a 4KB window placed between 2000h and FFFFh. The window can be mapped to different banks for read and write operations via two control ports.

It supports an optional internal/external backup battery to keep the data in the SRAMs valid across power cycles.

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.
