Chuck, what (in this context) is a “MAC”?
Multiple Access Controller--pretty much just a software-programmable

4-Cyber configurations sharing 4MW of ECS and multiple peripherals.

Wow, more than hundred of these CDC drives??? This must have been a massive
installation! I didn't know so many disk drives could be combined with
Cyber systems. Thanks for the insights!
Pretty much any of the big mainframes of the day - IBM, Univac, CDC,
Burroughs, and so forth - could deal

During my mid- to late-80s tenure at Georgia Tech, we had 2 x Cyber
180/855, 2 x Cyber 180/830 and 1 x Cyber 180/990. I'll have to ask around
for someone with better memory than me as to how many, but we had quite an
ocean of disks.

Dunno.. but look at the bevy of machines in the lower-right, the ones with
clear windows in the top. Those are all platter drives (HDD), aren't they?

I suspect that the cross and 3/4 cross CPUs are CDC CYBER 170s (or 180s).
So, not really IBM at all

A bit of Google-fu suggests that this is part(!) of an installation that
includes
a Siemens 7890
An IBM 3090E (those crosses right of centre)
A Cray X/MP (don't think it is in photo)
A substantial VAXcluster (part of which is just visible at the back on the
right)
