One more thing: I assume it is not to be expected yet that ASV can be
run? Haven't used it for ages, but developed software on it for several
years in the early 90s.
The attached screenshot shows the result of trying to boot from an image
of the original Maxtor drive Atari optionally delivered instead of a tape.
I guess I am one of the few who purchased a legal copy from Atari ;-).
