I received a wonderful link from Dave Carroll today, with pictures of a
4 CPU PDP-11/74 system.
The system, unfortunately, does not exist anymore, but if anyone still
had any lingering doubts, these are some beautiful pictures...

Thanks for the link and a trip down memory lane -- when computers (and
more specifically the PDP-11) were the stuff of dreams, and taking
pictures was expensive :).

In those days I was working with CDC Cyber-17 systems (anyone remember
those) and my camera was a Kodak Instamatic...

Thanks for sharing that. Amazing that even in the PDP-11 era there
were already multiprocessor systems, I never really realized that.

What immediately strikes me, is the high build quality; after all
that time, how it still looks very solid and well engineered! It
really saddens me that I wasn't around back then, or too young
anyway.

Thanks for sharing that. Amazing that even in the PDP-11 era that


there were already multiprocessor systems, I never really realized
that.

What immediately strikes me, is the very high build quality. It looks
very solid and well engineered! Especially after all that time, my
compliments also for whoever was or were responsible for the excellent
work in terms of maintenance. It really saddens me that I was not
around back then, or too young. They sure don't make systems like this
anymore.

There were multiprocessor systems before the PDP-11/70 (or any PDP-11) came
along: The IBM System/360 Model 65MP, the DEC PDP-10/55 (a master-slave 10/50
pair), the entire point of the MULTICS (MULTiple Independent Computing System)
project...

Well, excuse me, not everyone is over a century old. (Hence also why I
asked.)

A few academic institutions developed multiprocessor architectures.
Ones that I am somewhat familiar with are C.mmp (pronounced C dot m m
p) and Cm* (C m star), developed at Carnegie Mellon University.....ah,
those were fun times....

Classic example was the Illiac IV.

That was the "Hydra" project, right? Yes, there was some amazing research
being done back then.

Where did you get this??

From http://www.multicians.org/
Multics (Multiplexed Information and Computing Service)

While Multi-processor is listed under "goals and Notable Features" it
was not the primary or even a major concept of Multics.

From one of the Multicians. Not my friend THVV. Should have checked before posting...
