GVP HD8+ and A530 100-pin internal expansion-connector.

[patrik]

Does anyone know anything about the 100-pin (2x50) expansion-connector found ínternally in the GVP HD8+ and A530?

As far as I know the only device manufactured for this expansion was a PC-emulator-card from GVP.

One interesting thing is that when following the traces to the connector on the PCB in the HD8+ and A530 it seems to have quite the same pinout as a ZorroII-connector.

I sent them a mail asking about it, but they havent answered .

If this expansion-connector is a ZorroII-slot disguised as another physical connector the big question is how much of the ZorroII-standard this expansion-connector supports.

Does it for example support another ZorroII device utilizing DMA-transfers (the GVP SCSI-controller is already utilizing DMA-transfers if I recall correctly) to be added to this expansion-connector.

It wouldnt definately not be a very hard task to build a converter from the internal expansion-connector to a real ZorroII-connector.

@Cyberus

You can buy two ISA-connectors, saw them off to create two 50-pin connectors and then glue the now edgeless sides of them together and tada - you now got yourself a 100-pin ZorroII/III-connector.
