See "14.14 What are the VAX processor (CPU) codes?" at 
http://www.hoffmanlabs.com/vmsfaq/vmsfaq_024.html

Where there are several model names listed for a VAX processor, the 
physical system enclosure and/or the upgrade path to the variant model 
was the difference.

Missing from that list are the VAXstation 8000—graphics on the VAX 
8250—and the VAXstation 3520 and 3540 Firefox and Fastfox 
multiprocessor workstations.

VAXstation 3100 model 30 and model 40 are a pair and differ by internal 
expansion, VAXstation 3100 model 38 and Model 48 similarly, and 
VAXstation 3100 Model 76.  No model 90 existed in the VAXstation 3100 
series.

Model 30 and 40 used the same hardware and differed by internal storage 
expansion, as did the somewhat-faster model 38 and 48 pair.

VAXstation 4000 VLC (KA44), VAXstation 4000 model 60 (KA46), and the 
model 90, 95 and 96 (KA49), were common upgrades from the VAXstation 
3100 series, as well as replacements.

References to other "VAXstation 3100" models posted around the 'net are 
in error.  Those were likely intended as references to or confusion 
around the VAXserver 3100 models, and which are licensing-related 
variants of the MicroVAX 3100 series.

> Then there were the VAX3100.

No, there wasn't.

There was a MicroVAX 3100 series.

The earliest MicroVAX 3100 models (KA41-based) were similar to the 
VAXstation 3100 models.

That was followed by various VAXstation 4000 and VAX 4000 series models.

There was briefly a VAXstation 100 option for VAX-11 (max of two on the 
VAX-11/780, one on the VAX-11/750, and the whole system froze when you 
moved the windows around), the VAXstation 8000 (VAX 8250), and a bevy 
of odd and seldom-seen VAXstation I and VAXstation II variants (all in 
the hundreds-series stuff, IIRC) that were never really recorded 
anywhere, and few of those were ever sold.  Various of those odd boxes 
were DEC customer special systems configurations or one-off 
configurations, and variously not products from what was then known as 
DEC central engineering.
