Gigatron OS playground

This project is intended for operating-system-like code supporting SD cards plugged the SPI ports of a Gigatron RAM & IO expansion board. At the moment, this is mostly a readonly file browser and loader than can be executed when the Gigatron boots and allows you to run any GT1 file on the SD card.

• Directory sys1 contains the readonly browser.

• Directory cardboot contains the boot code that has been integrated into the devrom.

• Directory stubs contains small programs that launch programs available in the rom.
