networking via SCSI?

Long ago when SCSI was young and just an 8 bit parallel bus, Ampro littleboards advocated using the SCSI bus for peer to peer communications, not just master/slave. Did anyone else do that? A fellow contacted me with this problem: I have a couple of Kurzweil synthesizers (/samplers/sequencers): K2000RS and K2600X . They have integrated floppy and SCSI HDDs for storing configuration, composition and audio sample data. They're actually 68000 CPUs with a Kurzweil OS, managing IO among peripherals (keys, SCSI, display LCD, MIDI, etc) and several proprietary DSPs. But there's no serial/network/etc IO. I'm interested in trying to use their SCSI to interface them with a (Linux) PC somehow. Any ideas? Like maybe some webpages describing projects that have networked older (preferably 68xxx) CPUs over their shared SCSI bus. My understanding is that a Kurzweil and a Mac were sometimes configured each as a SCSI device on the same SCSI bus as the HDD, and either host could alternate accessing the HDD once the other host was no longer issuing potentially conflicting SCSI commands to the HDD. I don't see how just read commands could conflict, but perhaps the HDD wasn't able to multiplex commands targeting different hosts in any overlap. But evidently people were transferring samples between Kurzweil and Mac this way. [I replied privately about the problem of multiple machines sharing a drive even if one is read-only] any clues or hints? thanks -- jeff jonas
