This was mostly lifted from my "tihello" example, but it required significant adjustments. This commit also introduces a font management system. A lot of fonts are available online, but sources aren't always clear so to avoid copyright landmines, I re-created my first 5x7 font from scratch. As it is now, this resulting ROM gets "Collapse OS>" to be displayed on the LCD screen. Much work still left to do. ref #41 |

TI-84+
This is a work-in-progress, this is far from complete.
Recipe
This recipe gets the Collapse OS shell to run on the TI-84+, using its LCD screen as output and its builtin keyboard as input.
Build the ROM
Running make
will result in os.rom
being created.
Emulate through z80e
[KnightOS][knightos] has a handy emulator, [z80e][z80e] for TI calculators and it also emulates the screen. It is recommended to use this tool.
Once z80e is installed (build it with SDL support) and os.rom
is created,
you can run the emulator with:
z80e-sdl -d TI84p --no-rom-check os.rom
You will start with a blank screen, it's normal, you haven't pressed the "ON" key yet. This key is mapped to F12 in the emulator. Once you press it, the Collapse OS prompt will appear.
WIP: the keyboard does nothing else than halting the CPU for now.
