After tinkering with fonts on the T/S 2068, I was wondering if something could be done on the ZX81 to change its fonts. The ZX81 does not have a way to define a new font, so another method would have to be tried.. Since I am using emulators, the ZX81 ROM is really nothing more than a binary file. If I know where the character definitions are stored in the ROM file, I could use a hex editor to replace these character definitions with ones of my own.
