I worked for the FutureNet division of Data I/O in the late 1980s. One disastrous product was a UNIX based coprocessor system that plugged into an IBM PC/AT. The idea was to run circuit board layout software and simulation on a PC. This would be less expensive than the Daisy, Mentor, or Valid workstations. The coprocessor was an Opus plug in board based on the National 32032 CPU.

When you ordered the package you got the coprocessor board and a 5 MB hard drive loaded with UNIX and the design software. On a good day the system worked. It was discontinued when PCs with the 368 processor were available.
