The z80 is an 8-bit machine, with 16-bit pointers, so although archive was technically memory mapped, it wouldn’t all fit-it was actually paged in to a 16KB “window”: The z80 assembly 2 programming environment was pretty spartan: there was no supervisor or memory protection, so if you had a bug you were probably going to crash the calculator (the dreaded “RAM Cleared” message). The 84 Plus had USB and a redesigned case, but the system was the same.

Thanks to everyone who has emailed to check on me-and I apologize for not being super responsive over email. In the space of a year I’ve gotten a new job, bought a house, moved. Wow, it’s been a while since I’ve written anything. This is not a coincidence because nothing is ever a coincidence with xkcd. There are also 768 bytes in the RAM buffer used to hold TI display bitmaps. I’ll take you through some of the highlights of Texas Instruments calculator hacking done over the past two and a half decades, along with an explanation of why these projects are so technically impressive. True to my interests, it’s all deeply embedded, pushing the limits of platforms that were obsolete when they were released. There was in fact a thriving scene of hackers who had bent these calculators to their will, writing games, math software, and more generally hacking on the platform just for the sake of it. You may be surprised to learn that some of these people didn’t exist totally in a vaccuum. The one who could put games on your graphing calculator.
