You have also missed some small relatively insignificant OS's. TPS (Tape Programming System) DPS (Disk Programming System) BPS (Basic Programming System although it might have been CPS for Card ) These all run on the System360/20 machines. <snip> CPS Card Processing System (I think that was the name - it's only been a few years). And somebody walked off with my original Yellow card (now a booklet if IBM will even ship it). Yes, the S/360-20 had a Yellow card, not a Green Card. My first paying job in data processing was on a S/360-20 (8K, with the I/O & Compute feature!) with 4 tape drives, a 2501, a 1442, a slide bar printer (just can't remember the model). And we had 2 072 card sorters, 026 punches, 129 punch/verifiers, and some other things I just can't remember model numbers for and for which I just couldn't wrap my head around programming (plug boards). I had come from a college environment where we had a S/360-30 with 2314 disk drives, so I was rather shocked to see SYSRES on a tape for when we ran TPS. We had 8K and we ran payroll for a few fairly large companies (we were a circus bureau) among other accounting stuff. Let's see you do that today on a PC (which probably has more horse power, and I/O speeds) with less than 256MB! [Can you say, code bloat?] And for a final laugh, we did it all with RPG (not RPG-II) or BAL IFF it couldn't fit in memory as RPG!!!
