It is an Example program that can be uploaded to a 68k mac using stm_send. It display a picture of a cat.
I was inspired by the work of @DavidLudwig on MacRomPicture. He made a ROM for Mac Plus in C ++ used to display an image on the screen.
As i was using a Mac SE/30, it was necessary to modify the code, which is specific to a Mac Plus. I had to adapt the management of the stack in order to be able to return to "Diagnostic Mode" after execution; it is thus possible to perform several tests without having to press the interrupt button again each time.
Oh, and my cat wanted me to change the picture displayed on the Mac...
- you need the stm_send tool and a mac 68k with Diagnostic mode
- build the binary file
- upload it with stm_send
