Just wanted to chime in as a happy RaSCSI user. I am using it on my Sharp X68000 with a hat that I built from a PCB + a bunch of buffer ICs.

It offers SCSI disks, CD, Ethernet(tap device on rpi side) and a way to share a Linux directory with the X68k.

Performance is well over what an early nineties computer could require.

First thing I fired up was MMDSP and listened to some awesome tunes available.
