The SWTPC 6800/6809 Emulator was designed to run 6800 and
6809 programs written for the SWTPC 6800 and 6809 machines without any modification at
all. This is accomplished by emulating all of the hardware of original machine not
just the processor and OS. The emulator will correctly execute all of the instructions of
the microprocessor being emulated except the 6809 SYNC instruction. The peripheral
hardware that is emulated is the hardware found in the systems that I personally own
and/or have knowledge of.
