These are currently minimal ROM images designed to boot something from the CF adapter and execute it along with an example loader bootblock.
They assume the presence fo Ben's 16550A UART card, CF adapter and 512K RAM/ROM.
For the simple 64K memory case see Ben's github for monitors, BASIC etc. These images are intended for development work to boot Fuzix and the like on a banked system.
