TODO - Keyboard layout. All the codes appear to have been implemented following the manual but have not been checked with hardware. The key repetition rate and delay need to be checked. - Video character ROM needs dumping. An apparently close Motorola published 7x9 character set has been substituted for now, but three of the codes (0x1a, 0x1b, and 0x1c) do not match the characters listed in the manual.
