David Boozer released a text document entitled Hacking the TI-85 Calculator on September 1, 1994, in which he explains how to do various things with the TI-85 graphing calculator. In particular, he details how to dump the TI-85 ROM and program the TI-85 in machine language (i.e., assembly). So, he was the first person to figure out how to hack the TI-85 graphing calculator to allow for assembly programming, and subsequently was the first person to write an assembly program for the TI-85. In fact, he even predates the infamous ZShell created by Dan Eble and Magnus Hagander/Rob Taylor.
