The VAXstation 3100 was an improved (approximately three-four times faster than its predecessors) VAXstation intended for demanding graphics applications. It was created by adding a bit-mapped display to a MicroVAX 3100.

It used the second generation of VAX CMOS chip-set technology, the same as in the MicroVAX 3500/3600 and VAXstation 3200/3500.

There were three basic models in the VAXstation 3100 range, in two generations:

• VAXstation 3100 Model 30 - based on the CMOS-1 CVAX and performed at ~2.8VUPs
• VAXstation 3100 Model 38 - second generation, based on the CMOS-2 CVAX
• VAXstation 3100 Model 40 - the same board set as the Model 30, but in a slightly taller mounting box, so it could accommodate more mass storage options
• VAXstation 3100 Model 48 - again the same board set as the Model 38, but in the slightly taller mounting box
• VAXstation 3100 Model 76 - the final member of the series was Rigel-based; this doubled the performance to 7.6 VUPs

Depending on the configuration, it could be a disk-less network node, a stand-alone work-station, or also as a server for up to seven other VAXstations. An optional MS-DOS 'software coprocessor' allows it to run un-modified PC applications at full speed.
