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

Later,

Will

    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
