Mitsubishi Melcard (edge connect type)

[D. Resor]

Does anyone recall what kind of hardware/software was used to read/write the
early Mitsubishi Melcard EPROM cards with the PCB edge connector contacts?

 It was explained to me by someone that a EPROM programmer could be used,
however I've never seen a socket which fits the edge card connector of these
cards.

I've uploaded an image of the edge contact end of this type of card here:

Seems these were also available in the SRAM variety as well.

Thanks
