Atari-Midi Archives

i recently found one (literally on the side of the road) plugged it 
in and it booted right up! the only thing i know is that i've always 
wanted one because in the 80's this was THE midi pc to have.

any and all links and or info would be GREATLY appreciated. looking 
for HW mods, i'm not afraid of a soldering iron, but a HD would be a 
pretty necessary thing.

thanks
