There also was the little detail that DOS360 could run on 16K and 32K machines while OS360 required a minimum of 64K (and I THINK that was with PCP). Both have evolved since then but I wouldn't be surprised to find that the minimum configuration for zVSE is still much less than that for zOS. ----------------SNIP------------------------ Not from direct knowledge but here it goes: Back in the early 70's we were running MFT on two mod 50's and DOS (sorry cannot remember the version) on 2 mod 30's . In any case we had a visitor from the Canal Zone and he (without asking) tried to load an object deck onto DOS. It couldn't as our machines were 32K and his DOS machine (according to him was 64K). I walked into the "mess" and took one look at the output and said our machine only had 32K. He was a warrant officer and I was (IIRC an E6 at the time) and I said well we can't load the deck because of the machine size. He laughed and said something like well we use DOS for important work and I said something to the effect "well we do our important work on MOD 50's using a modern OS and reserve the 30's for printers. He did not like my answer so he left and I guess he tried to get me on insubordination but my boss quashed that. He was a GS14 and that pretty well out ranks a warrant officer.
