Yes, I have been looking at that before I got busy with "real life" (is
academia real? discuss...) I figured that chopping off the second (RAM
controller) AVR and add SD-card smarts to the SCSI control AVR might be
possible.

preliminary brainstorming on it, but think it
should not be too hard. The
SD card interface is very simple, both from a logic and electrical point
of
view: if you don't care much about speed it can be done with SPI. (the
speed
should be sufficient to keep up with 68k Mac, Amiga and Atari) All logic
can probably be done in a single AVR or even PIC chip, if you run that at
3.3V, the only additional hardware is the SCSI level shifters.
After seeing this project http://micha.freeshell.org/ramdisk/index.phpI'm very
inclined to at least TRY something on this area. Seems simple
enough for trying.
