@PeterLudemann @not2b Excellent work. I applaud efforts to improve OS/370 (though I myself never had to work with it very much relatively, in contrast with OS/360 on the UCLA 360/91 with which I was intimately acquainted). When I was at RAND the 370 was on the main floor and my basement computer room had the PDP-11s and IMPs and TIPs and such that were my domain. Though I did one day impact that 370 in a big way. That was the day smoke filled my computer room from (we learned later) a failing PDP-11 power supply, and (for the one time in my life) I pushed the "Big Red Button That Though Shalt Never Push" under the glass shield just inside the door. There's serious friction in your head (just for a few seconds though) about pushing that button, I'll tell ya'! That killed the power to everything in my computer room -- 11s, all the ARPANET equipment, but ALSO instantly killed all the power to some disk drives for the 370 which were also in the basement in a nearby room. Quite a day. Management was pleased though, it turned out the halon was about to fire and that aborted when I pushed the button, and that saved them a bunch of money on recharging.

I've told the story of when the DEC CE showed up and found the molten power supply, I wanted to get the RAND photographer to get a picture of it but the CE hid it under his jacket and ran out to his car with it.
