Opcode Studio 4

I bought three of these units:

in great condition at the flea-market. What I gathered from the net is that the unit needs a Mac to run, with a pre OSX OS on it (eg. OS9), using serial port and OMS software. Since the OMS dates from the MIDI operating systems war era, I doubt that I could get them to work on anything else than Mac, maybe on OSX if I try hard enough. It's a shame, since these units seem very powerful with 128ch of MIDI and SMPTE. I read somewhere that the unit is capable of some basic MIDI routing in standalone mode, but can not confirm it. Should I even try bothering with these or just ditch 'em?
