I remember VMS 3.x fitting on a few tapes, but that was back in the
day when DEC was _shipping_ machines with 2MB of RAM (max of 8MB). At
SRC, our first 11/750 shipped with 512KB, max of 2 MB until I added
the magic wire and swapped out the memory controller. :-)

If you mean BSD, I'd expect SLIP or PPP... the 11/725 _should_ have a
DMF-32 combo I/O card - 8 serial ports, 1 sync serial (for DDCMP,
etc.), one parallel that can be used to drive a line printer.

As for VMS... the connectivity options on older versions of VMS are
more limited. We used to use that sync port and a DECnet end-node
license key to hook it to a similar port on that 11/750 mentioned
above. It needs a sync modem eliminator in between (the modem
generates the clocking, not either end), and it's not quick, but you
can set up DECnet to move mail and copy files and log in remotely.
Ethernet is a possibility, of course, presuming you have a DEUNA or
