I'll assume they're some variaty of SMS-1000. I've got a pair, mine came
with PDP-11/73 CPU cards, and 256KW of RAM in the form of DEC boards. The
I/O is not Q-Bus, and is SMS proprietary.
The systems you're looking at could be /23's or /73's. Based on what I've
seen I'll assume they've got one floppy drive 5.25" or 8", and one Hard
Drive. Since they are in a Rack, and they've been used as a security
system, they might have some interesting cards and peripherals.
One of mine is running RT-11, the other has given it's CPU to the PDP-11/73
I built using a BA123 and all kinds of cool parts :^)
