I've run it on Apple][, NS* Horizon(z80), and PDP-11/23 and all worked
the same and fairly well though a bit slow. it was honest pascal and I
used it to teach many people the language.

All of the systems I used DIDNOT have disk change logic, nor was it
needed. the P-system does volcheck on a disk before writing or reading
to make sure it's the right one. Likely the volume was of the same name
or the kernel was corrupted. I know this as the NS* was only 80k per
drive and three drives and I'd often put the wrong disk where ever.
Also Most version had dupdir so if one directory was munged you could
copy the other and use it.
