These machines do not have a 60pin cartridge slot.

Well, I need msxholder explanation...

Still based on his infos: " The unique 60-pin cartridge slot has 6 special pins named abcdef: a, b and d are shield, c is sound in, e and f are slotselect.". I think it makes sense when using the Yamaha SX-101 extension with these computers.

There are several photos with an MSX cartridge inserted in this slot. Also if you count the connector pins on the PCB, there are 2 x 25 pin. In addition, the SX-101 expander connects to the MSX via a cartridge.

According the cartridge slot pinout, only 2 pins are free.

I don't see how there could be 6.

The video modules are probably unusable in the SX-101.

As easy it can be
There is on the msx cartridge more space then 50 "fingers" in the opening
They use the full lenght of the cartridge insertion .
and also use two gaps like the old shugard connector.

do you mean that it is non-standard connector there and if your PCB is wider you can have some extra pins connected? but if your cartridge is standard one it will fit but use only 50 of them as usually?

sdsnatcher73, can you take a picture of the connector ?

On the PCB picture below I see 50 pin only but the resolution is low.
