How much memory did MG91E, MG92E and MG93E have? Later model groups? -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 עַם יִשְׂרָאֵל חַי נֵ֣צַח יִשְׂרָאֵ֔ל לֹ֥א יְשַׁקֵּ֖ר

Everything in our DC with "IBM" on it was tall except the 3174 controllers. Had a little NCR 10000 minicomputer sitting in the corner that you could trip on if you weren't paying attention. Couldn't miss the "big blue" stuff.

The first one I ran was VM/SP with an OS/VS1 guest. I don't remember if we migrated to MVS, but I don't think so. The other one I ran was VM/SP only. So 4331 and 4341 were "counter height" but 2-3 units long and the 4381 was a 1 unit upright? I contracted to help a neighboring site recover their CICS install, someone had deleted all DLIBS. They had a small 4300. I'd said we could do it in a day, until I saw how slow their tape moved. It took over an hour just to RECIEVE the tape :-) Remember "Meaningless Indicator of Processor Speed" :-) Len Rugen rugenl at yahoo.com On Thursday, July 31, 2025 at 11:27:27 AM CDT, rpinion865 <[email protected]> wrote: In 1981, running IMS/DB/DC TSO/SPF (not ISPF), IMS MPPs, and batch on 370/168.
