Nice turn on topic there. My complements.

The x86 clbutt processors do include a bounds check (bound). It generates a software interrupt 5. It was never widely used under DOS since it interferred...

The ISIS we (at least 'I', I think 'we') were talkinga bout was a large (but at the time considered small) development system built by Intel. A bit bigger than a very large microwave oven. Usually had one or two 8" floppy drives in it. I mention this because "...ran ISIS." sounds like "...ran CP-M" or "...ran Windows" and as it happens I'm aware that there was an obscure software package around at about the same time, also called Isis." I see below in you use of "ISIS" that you may mean the same thing I-we do, but I wanted to be clear were I'm coming from, at least.

V1.2, as I recall, was the more popular version of 1.x, but 1.1 was available as well. V2.2 was around for a long LONG time and is still popular in CP-M circles. V3.0 got a lot of circulation, but most didn't bother with it unless that had banking hardware. It didn't need it, but you usually didn't bother unless you had it.

PDP's. Right. Peripheral Interface Program. Did "copy" and a bit more. Yes, I think so.

And I'm getting ready to take my kid to school this morning.

And probably will.

Me too, but I try not to admit it. Even to myself. Mostly I just accept that the retrieval system is a bit slower than it used to be.
