The sun 3/80 was the last system from Sun to use a motorola
processor in this case it was the 68030 a nice system. and
about as fast as a sparcstation 1. and also shared the same case
type. on the back is the usual keyboard, scsi2, aui, and serial ports
the video used a P3 type card though. (no s-bus slots on the 3/80).
