The 11/750 shipped with 512KB standard (2 x 256KB boards), with a max of
2MB (8 memory slots). Over the years, two different memory controller
upgrades were available - one that let you use 8 x 1MB boards, and
another that allowed 4MB boards, but you were limited to 14MB total,
probably due to memory space conflicts with I/O.
But VMS 3.x will run in 2MB for certain... not sure about VMS 4.0.
I would expect VMS 1.0 would run in 512K, but I've never used it (though I
do have the paper manuals at home, in storage).
Not sure what you would have had in the lab in 1980, but it was probably
an 11/780. That's one of the few models I haven't worked with, so I'll
leave it to others to comment on its memory.

that there was no way to multitask in anything under 8mb
of ram.
Heh. When I first came to Montreal, we had a VAX running VMS,
supporting the whole lab. Multitasking.
I don't know how much RAM it had, but more than 8M would surprise me.
This _was_ 1980. Heck, we had only about 30M of _disk_!
