Yes... a common 1980s small office configuration. Pretty big for a
single-user RT-11 system of the day (I was using a single RL01 for my
OS and development environment and a single RL02 for customer data in
1986). Not so bad for a small RSX-11 or small RSTS environment (we
were using a machine with only 4 RL02s for a RSTS-based accounting
system for a multi-million-dollar company in 1984).
This does
bring up an interesting question. ?What percentage of people
with
PDP-11's have Unibus PDP-11's. ?Also of the people that do have Unibus
PDP-11's, how many have a large number of PDP-11's?
Q-bus PDP-11/23 in the Dec half-height cabinet with 2 RL02's (a common
configuration apparently). It came with two VT-100's and a LA36 DecWriter II.
Sounds like a small RSX-11 or small RSTS system, then, or perhaps it
was used with TSX-11. One doesn't usually see multiple terminals with
RT-11.
My second PDP is an 11/73 in a desk-side case (is that
the microPDP-11/73?)
The MicroPDP machines I've seen are in a BA23 (could be racked, could
be in a desk-side pedestal), with a 1" MicroPDP nameplate near the
power switch. It's spring-loaded, so you can pull it out and turn it
90 degrees for upright or racked orientation.
My college gave me a PDP-8 in a full rack with a fixed
disk...
Oooh... nice. What disk? RF08? RK05F?
but I had to re-home that when I moved out of my
parents home and into an apartment. At
the time they weren't particularly collectible or uncommon. I've begged
the new owner several times to consider returning it, or at least leaving
it to me in his will.
Good luck on that. I myself held onto a Quest Elf for a friend who
had to purge his place when he got married. I returned it to him many
years later when he was divorced. He was 16 when he built it and its
hand-made aluminum case and extra I/O to control the robot it sat at
the top of. He was quite happy to get it back in perfectly working
condition after so many years. I was happy for the use of it over
those same years.
