The character set's pixel map is in ROM, not RAM, so you won't find it there.
If I understand your problem, I believe what you want are the 6 bytes beginning
at 65516 (high RAM) – this is where the M100 stores the pixel map for the
character position it's currently "blinking". Same FORMAT as the graphic
character table: 6 bytes, 1 for each column, in each byte/col the sign bit
corresponds to the lowermost pixel, etc. (Ah, if only Tandy would sell a source
listing for the ROM – I think they don't WANT you to know this stuff! Sigh…)
