Oops! Sorry, thought you were talking about the new Dual IDE board

Hi John,

There is no problem copying CF card to CF card within CPM3.
I don't actually have a dual IDE S-100 board built yet.
We were talking about making an image of a CF card containing CPM3 in MS
Windows or DOS or LINUX, and making that image available for others to use.

Best regards
