Brandon Wilson (@brandonlwilson) shared his stories about hacking TI calculators (and other things).

TICalc.org has the latest on getting started yourself including Z80 assemblers, or start on Brandon’s website: brandonw.net

Bradon will be speaking at Hardwear.io, a security conference for the hardware and security community. The conference consists of training (11th - 12th Sept 2018) and conference (13th - 14th Sept 2018). It is in The Hague, Netherlands. His talk is The Race to Secure Texas Instruments Graphing Calculators. He will also be hosting a village called Dumping the ROM of the Most Secure Sega Genesis Game Ever Created.
