Raspberry Pi GPIB

I know there is some stuff on the Linux side for working with GPIB (IEEE 488), but has anyone done anything on the RISC OS side, particularly interfacing with digital voltmeters? I’ve an Archive subscriber who is using RiscPCs as data loggers/controllers via a GPIB podule, and he’d like to upgrade and shrink down his kit.

If you have a GPIB shield which directly connects to GPIOs e.g. this one:

Then porting the C code to RISC OS should be not too difficult.

If you have a commercial USB-GPIB adapter I would think it is more difficult. It looks like nothing came from that:

At first SerialUSB module would need to support the used USB chip.
