Brian thanks again for posting the ROMs.
They dropped directly into my new project unmodified!

    In the emulator I am working on. Ow, I have to redo the fonts.  I'm
    free to use whatever I want.

    So, which one of these fonts is actually used by the dvi?  The 8x8
    or the 7x8?

        Ooh! There are actually two fonts in the 4K ROM

        Here's the second one

        This is the same font, but with only 7 bits used. I'm betting
        this is the same as the internal font on the M100 itself. Here's
        one of the characters (255) for comparison:

            Hey, the file works with my Commodore font editor!  =)  I'm
            totally going to add this as an optional font in my terminal

                You know what, I realize that I went straight to that
                screen photo image because I was looking for a clear
                image that had my X<char>X pattern in 80-column mode...
                and it's really not so blurry, but the capture in
                "Snapshot_20210127_233755.jpg" is sharper and does have
                the full character set showing.  Even though they're
flanked by square brackets I think I can work with it. (the square brackets don't go to the full left and right extent of the character cell, that's why I used X.) Don't worry about going to any trouble for a sharper
                screen photo.  For my cleanup/rescaling of the original
                font I've been working off a handheld iphone photo of my
                monitor.

                I also whipped something up to display the ROM data as
                large block pixels for an absolute reference to the
                original intended shapes so I think I've got everything
                I need (except time) :)
