So, the freshmen at my school have been getting 84+Ts as mandatory for the courses. For those of you who don't know, this is basically an 84+, but completely black, without I/O port, and with an exam mode indicator LED at the top. It was a bit cheaper, which is why the school chose this instead of the regular 84+. They don't care about the exam mode.
Some knew about my "calculator knowledge" and went to me, expecting me to put some games on it. That's when I found out that the Asm(, AsmComp( and AsmPrgm tokens are just completely missing on this calculator. Freeware apps don't validate. This has probably been done to prevent Z80 freaks from hacking the LED. The problem now is, how do you get arbitrary code running on it? Has someone found the proprietary key for apps? Can you send over a hacked OS?
