 Sorry, I'm just back from a vacation trip and I'm still not back at
work yet, so I'm doing this from memory. It been at least a year since
I sent that disk, but I seem to remember that I sent you an email after
I sent the disk saying something like "Oops, by the way, by mistake the
NSDOS disk I sent you is a special version compiled to load at 0100 hex
not the normal 2000 hex." Look at the label, if this is the case it
should say North Star DOS (version something) AT 100. So (if this is
the case) you would need RAM starting from 0000, and BASIC on this
disk would expect to find the DOS I/O vectors starting from 0100 hex,
but the BASIC programs would work with the normal version of DOS.
 Without being able to search through my old email, because I'm not
at work, thats how I remember it. Sorry, I just seems to have gotten
in a hurry and sent the wrong DOS on the disk without thinking. I run
CP/M also so I just naturally start RAM at 0000.
 I hope I'm not thinking of someone else I sent NSDOS to.
 I'm glad you're having so much success.
