Do you think i'd be possible to just downlaod the mem area 0000-8000 
and I'll look to see if there's any hint of rom changing.... you can 
either do this using the link port (routiens for th pc are available 
at ticalc.org), or you could copy it into a string a bit at a time 
and download these (i.e. 2 16k strings)
