- I have tried to run this using APE software on an Atari 800XL, but after the READY prompt appears the keyboard has locked up.... What does load with OS-B mean? Should I assume that this dump does not work with an Atari 8-bit computer? or is it non-XL compatible?

Hi!

OS-B is the operating system from the 400/800 models, so anything requiring OS-B is inherently incompatible with XL machines.

"Run with OS-B" is an instruction that's meant primarily for emulator users.
