After initial success building a Multibus chassis with a self-contained VT-100-compatible CRT display terminal to OEMs, the company designed and built desktop workstations named Unistar using the Sun-1 board, which was based on the Motorola 68000 CPU, and which ran UNIX licensed from AT&amp;T.
Other firms at the time were competing to build the first commercial UNIX workstations based on inexpensive microprocessor-based Multibus-single-board CPUs.
