1 MB in 1987?
Good for PC, but not for mainframe IMHO ;-)
BTW: the machine model and amount of RAM are completely irrelevant in
the story.

Many a machine running DOS and later VSE had 1 Meg memory.
In 1987 we ran an HDS clone with 1 Meg of memory. Two CICS regions. It was
flat out most of the time and compiling in prime time was largely verboten.
I convinced my manager if we could get more memory it would alleviate some
problems.
When we went to 2 Meg it flew (like a turkey).
We seemed to a manage a whole savings and loans application with that and
less than 3 GB of dusk.

Hmmmm. I worked on a 360/75J in 1979-1980. We had 1Mib "high-speed"
RAM, and 2Mib of LCS storage.

"It's the late 1970s, and this data center has a high-performance IBM
360/75 mainframe that sports a massive 1 MB of core memory -- one of only
four in the world,"
I might believe late 1960s, but by the late 1970s the 360/75 was well and
truly obsolete and 1 MiB was nothing to brag about. We had 2 Mib at the
Technion in 1973, and I'm sure that places like NASA Goddard had more, to
say nothing of the tri-ASP 195 complex at Suiteland and the intelligence
facilities in Maryland and Virginia.
