Ok. If it's about 10cm (4 inches) high, it's probably a Model 30.
If it looks as if it can hold full-height drives, it's probably a Model
40. There's normally an actual model number on the back.

It probably has better SCSI capability than the Q-bus system. This
capability may become valuable as you get further along.

See SCSI note, above. Actually, there was a Q-bus card (KRQ50?) which
connected to a non-SCSI CD-ROM drive, but they're rare, and the
associated CD-ROM drive (RRD50?) was no great prize, either.

See SCSI note, above. Cheap, large, working SCSI disk drives are
also commonly available.

Look for "M" numbers on the card handles. Some cards also have info
stamped into their metal frames. Given an "M" number, Google can
usually find useful info. It was a popular connector, used for SCSI and
serial port cards, among other things.

You may be able to find someone local (more than I, anyway) who could
supply TK50 (or TK70) tapes for a classical (that is, slow) VMS
installation from tape. Or you can make a cluster with the
SCSI-equipped VAXstation. (OS installation over a serial line may not
be practical, but you can make a DECnet link over one. Ethernet'd be
faster, though.)

That's only software. TCP/IP kits (free-to-hobbyist, even) are
available from multiple sources.

Do a hardware inventory, and find out with what you're working.
