Today I visited OmegaMSX with my MSX machines, and we found some non-standard stuff on my NMS-8280:
First of all this little PCB on top of the PCB:
This PCB could be found at the bottom:
With these connectors:
Which works out like this on the backside:
OmegaMSX thinks this might have been done for a "Kabelkrant" (No clue about the English Translation for this). It was done in quite a professional way.
Also another thing we ran into: Next to the FDD conenctors of the NMS-8250 there is some space where you can mount a connector to create a 3rd cartridgeslot :)
