I think there where some programs in French but the 8-bit line was not as populair as the ST/Falcon series.
Just look at the ebay sites to find them...
Secondly as for the eprommer, when you want one for the atari look at ebay. Sometimes you can find them.
For the pc also goto www.ebay.com and type by search EPROM you will find some eprom programmers for the PC very cheap.
