Re: CF card images

[Elsid <le...@swiftdsl.com.au>]

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
Leon
