I've had an interest in them for thirty years, collected a bunch of them in the 80's up through the versions that could run Unix, gave them away, and have spent the past decade building up a small collection of them again. They almost got it right. 68000, bitmapped display, but missed the importance in the marketplace of a GUI. It never really evolved past it being a slightly extended UCSD Pascal environment, though implemented with a compiled Pascal and could run diskless, though. Local peripherals were built on Apple II expansion cards (w/o DMA capability). There was a 5" and 8" floppy disk card, and a flat cable interfaces for Corvus hard disks and Mirror backup tapes. There was driver support for the networked print servers. While the MESS work was going on a month or two ago, I had thought a bit about what it would take to write a Corvus OS driver for an Apple II CF card board. Years ago, I had gotten a couple of low speed Apple II SCSI cards thinking I would try getting those to work on a Concept.
