Youíll have to do your own firmware mods, as well as patches to OpenCBM. Thereís no reason why you canít implement something like this, and the existing GPIB code for talking to PET drives should be a good starting point.

In particular:

Hope that helps you get started.

My ultimate goal is to be able to use the ZoomFloppy to emulate an HPIB disk drive, either with the HPDrive project or something else.
