The A3000UX was released with AT&T Unix V4, iirc. The machine was a standard A3000 68030 m/b with early roms, the aforementioned scsi tape drive and an A2410 graphics board (for the Unix display). There was also a version for the A2000 that used special boot roms on an A2630 68030 accelerator. I once had both machines, having bought them off a guy who worked at the Univ. of Lowell (where they designed the A2410).
