i am pondering if it is possible to run QNX2 on VMWare and be able to communicate through arcnet to other nodes? Is there a VM besides VMWare that would work?
I do not know of any VM that supports ARCNET.
Even if there were a VM that supported ARCNET, it is rather unlikely that it would have a virtual driver that used the proprietary Cormen interface. Although I don’t remember ever seeing it documented, it wasn’t all that secret that it was just a somewhat unusual memory mapped interface to a standard arcnet chip that usually was addressed via I/O. That and it had some proprietary rom to allow booting over the network, as well as some EEPROM to hold settings.
