Ive got the "NTSC PC ditto" it doesn't seem to in the internet witch I think it's odd but any way. Over the years Ive lost my copy of "M$dos 3.3 US" the only M$dos 3.3 I can find on the net is the french version only, anyone here have a US version that use 720k format? If so pleas use *.st or *.MAS disk images. Thanks.
