Yes, I think this is known as PET-switch, MBS-xxxx (I forgot the actual number). When I rescued PET systems a couple of years ago, I came across a couple such setups. They appeared to consist of one master unit to which you connected the floppy drive, hard disk, printer etc. This master unit connects to your first PET in the chain, then you use 25-pin flat cable to chain to a daughter unit connected to the next PET in chain, and then another length of cable to the next daughter unit. I'm unsure if there was any need of termination or if the last PET somehow connected to the master, but I don't think so? The Corvus constellation multiplexer however appeared as a star topology, where users would connect their Hardboxes by one cable each to the multiplexer which in its turn would connect to a Corvus hard disk. Nowadays, those who have multiple PET systems set up probably can afford one petSD or other device to each so no real need to daisy-chain all computers to one poor memory card device. :-) Best regards -- Anders Carlsson Message was sent through the cbm-hackers mailing listReceived on 2011-06-20 15:00:29
