Some stuff didn't seem to acknowledge that types other than B-A-I-T 
existed.  DOS BOSS didn't understand the other types and let you stretch 
the DISK VOLUME header over them (otoh, my own version, DOS Manipulator, 
does recognize them; that's how I patched STOS).

Could well be.  I've seen DOS 3.3 hacks that only show locked files.

EDM does the opt-ctrl-reset thing too.  I used it when doing a couple of 
my filecracks.  Didn't know the 8C had that.

Maybe the 8C ROM was based on EDM?

I still wonder if it's possible to come up with a replacement for FPBASIC 
because I never felt right packaging it with my emus.  The closest I got 
was ripping it from a shareware emu that had custom ROMs (and for which 
FPBASIC was separately licensed from M$).
