GEC 4310

The 4310 was another significant hardware change. The 4310 uses Motorola's MVME187 88100 based VME system, and runs a 4000 series instruction interpretor. Systems are available in 19" rack mounting cases, pedistalls looking like PC tower systems, and pizza boxes. The 4310 series does not support any of the earlier 4000 series peripheral controllers. It has an IMC I/O processor (like the 4x6x) for the on-board peripherals (serial ports, ethernet, clock, interval timer, SCSI), and external VME-based I/O processors for additional cards such as multi-port async or X.25.
