# 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.**
