Isn't the information in this already largely known and documented? There have been over 30 years of tinkering, reverse-engineering work and assembly programs on the (e)z80 TI graphing calculators.
Incidentally, that lineage has finally come to an end as TI has released the TI-84 Evo-T, which uses an ARM Cortex-M core and a firmware apparently rewritten from the ground up.
