Anyone got a Dragon 32 they could try this on? :-)

CoCos and Dragons were completely different than the original TRS-80; the CoCo only carried the TRS-80 badge for it's brand recognition.

Even amongst actual TRS-80's, the Model I is only partly compatible with the Model III and Model 4.

Dragon 32 is a 6809 machine, TRS-80 uses Z80.
