Hi Ken,
Thanks for the pointer. I didn't realize there was an emulator out
there. Hopefully my machine should get here today!

Thanks Mike! That's the ticket. Now, I just need my M100 to show up.
Later,

All,
This is my first post, but hopefully not my last.
I originally had an M100 in 1984 that I hocked for $50 bucks at
a local pawn shop for food money in my freshman year. I never
went back (I didn't get the $50 plus interest for ages). Now,
it's 38 years later and I'm finally getting it out of hock (so
to speak). I remember writing a basic program that read the
character bitmaps out of ROM (at least that's how I remember it)
and used the bitmap as a basis for a banner in the same font. I
think I'd like my first program on my new/old M100 to be a
banner program and so I'm digging around looking for where, in
ROM, the character bitmaps are stored. I've looked here, there,
and everywhere to no avail. Is there a set of bitmaps stored in
ROM, and if so where?
If I remember correctly, each character was represented as a set
of 8 (maybe 7) 6 (maybe 5) bit binary numbers:
001000
010100
100010
100010
111110
100010
100010
000000
or somesuch for A...
resulting in something like:
1
1 1
1 1
1 1
11111
1 1
1 1
being displayed. The zeros on the bottom and right may be on the
top or left, or not there at all, but there are spaces between
and below characters, either in the bitmap or added by the
display functions.
Thanks!
Will
