CROSSDOS
No, I can't really give info on dollars or dates. For the A500/A2000 the
upgrade will be a matter of changing a rom chip, and installing all the new
workbench files onto your SYS: partition of your hard disk. (application
software may have to be reinstalled, or at least their special entries in
the startup-sequence and/or mountlist will have to be reinstalled)
There are a number of programs that provide a point and click text based
interface for moving files, copying files, etc..
