Besta series (Besta-88 and Besta-90) of engineering workstations. Former was a deskside model, latter a desktop.
Design was apparently licensed from Force Computers GmbH (SYS68K series).
These were 68020- and 68030-based graphics workstations with VME bus. Ran mostly UNIX (System V R3.1), OS9 apparently was in use too. Linux 2.0 was ported much later, by a customer.
No known emulator. Lots of unemulated chips -- 68230 PIT, 68561 MPCC, 62421 RTC, 6850 ACIA, Intersil ICM7170 ...
Graphics cards were optional, the machines could be run headless (with up to 24? directly connected serial terminals).
