I'd noticed that. It does make me wonder; is there a known list of scenarios where they're preserved/corrupted (like the later PRMs provide) or is it just a case of suck it and see? (And/or reading a disassembly.) Or do all MOS calls preserve?

Re: BBC Master 512 reset...

Presumably, prefer an internal tube, and enable the tube, then reset the machine:
*CONFIGURE INTUBE
*CONFIGURE TUBE

(opposites being EXTUBE and NOTUBE, and I think you can shorten *CONFIGURE to *CO.)

I believe it resides somewhere in the region 3400000-37fffff but that is a large region for a 64K ROM.

Makes you wonder why Acorn didn't put a knob on the Beeb to begin with. There was a controller inside.

Yes, AGA32. Was £499 exc VAT. It was also available bundled with an A4000.

I suspect the difference between the two is likely just to be a processor swap, and the fact that the 486 model comes with 4MB RAM as standard.
