Here's what I know (I've Cc'ed this reply to the port-vax list in case
anyone would care to correct/add to this information).

This table is snipped from the "VMS CPU Model Summary (14th October
1993)" at http://www.anglia.ac.uk/~systimk/History/Vaxes.Txt

AFAIK, there are four main "types" of 4000 machines:

4000-100/100A/105/105A(?):

Small servers in cabinets that look like the uVAX3100-40 (double-height
"pizza box"). SCSI and Ethernet on CPU board. Qbus expansion possible
through cable to external Qbus cabinet.

4000-200:

CPU upgrade for uVAX3600 (and others?). DSSI and Ethernet on CPU board.
No SCSI (but possible addition through Qbus card).

4000-300, 400, 500/505/505A, 600/605/605A and 700/705/705A:

Qbus machines with built-in dual DSSI disk controllers and built-in
Ethernet (on the CPU board). No SCSI (but possible addition through Qbus
card). Cabinets look a lot like the uVAX3300/3400 cabinets, only a bit
larger.

4000-VLC, 60, 90 and 90A:

Workstations in "pizza box" cabinets. However, the cabinets are not
identical to any of the 3100-series, they are 100% plastic and a bit
more "rounded". Ethernet and SCSI on CPU board.


I have no idea how much the different types have in common with each
other. We need more info from DEC about this.
