Hi folks,

A good one to look at is:

http://www.circuitgeek.com/the-outstanding-avr-based-scsi-ram-disk/

The above project has also been adapted to work with a standard ATA hard disk and Compact Flash. It's an open development project: you can download the source code to the firmware and schematics. His website seems to be down right now though.

And there's also this:

It seems to me that a good route would be to build, say a QBUS card driven by a microcontroller. Given that even an AVR can handle SCSI comms at a hardware level by itself it can probably handle MSCP and a lot of the interface logic.
