Overview

Omron sold a line of m88k-based workstations on which the MACH operating system ran on, which includes the CMU's original m88k-port and Omron's own MACH-based UniOS. These computers were distributed almost exclusively in Japan and are very hard to come by. The LUNA88K was Omron's original m88k-based offering after which the sucessor LUNA88K² came.
