Hi, I was wondering if anyone knew any ebooks or tutorials on how TI-83+ Z80 ASM works? (Like a comparation of the Pentium Processor Manuals, which gives you info for how opcodes are constructed and what bytes are needed and how those bytes are constructed). Reason I want to do this is so I can write ASM proggies on my calculator itself!

Thanks for your time!

I have found the actual z80 manual, yet I don't know what ports there are on the calculator as well as what memory lies where.

rhyno_dagreat,

check some emulation sites, like zophar.net... maybe you have luck, and can extract some info from somebody´s ti83 calc
