[M100] Software Archives

[Robert]

Just picked up an M100, completely new to this wonderful little machine. 
Would love to explore a bunch of software other than what came with the 
unit I picked up locally. I've found some stuff out there, but is it 
generally the case that the commercially available stuff hasn't been 
archived? Being an 8-bit Atari guy, I'm used to being able to grab 
basically anything that was made back in the day very easily. Is that 
not the case with the TRS-80 stuff?
