Ah, I was momentarily forgetting Valdocs. My QX10 came with CP/M and
that's all I've ever run on it. I find it's a pretty nice CP/M box,

To be fair, I've had a lot more problems with 'flakey components and
out-of-adjustment drives' on modern PCs (not mine I hasten to add..), and
indeed software problems, than on any classic I own.

Isn't that what logic analysers are for :-) (Note the smiley...)

The alternative perspective is that I enjoy tracking down faults. To be
honest, a classic computer that works fine, and that I fully understand
the hardware of, is of less interest to me than one where I either have
to find and oscure logic fault, or have to work out how it really works
(possibly to be able to find said fault).
Pointless. Probably. It's like solving any puzzle...

Ah well... I'm a hardware guy to the core (literally :-)). Microcode is
OK, machine code is getting far too close to 'software' for my liking.

Not at all... Just a different interest, that's all
