Re: 1541 can write 1.2 DS\HD Floppy

I've experimented using HD disks in a 1541-II drive some years ago, but the results were disappointing for me.

Re: 1541 can write 1.2 DS\HD Floppy

oh, you probably didn’t find the Hungarian People's Republic, otherwise you wouldn’t have to google IZOT - the brand that produced floppy disks for the countries of the "Warsaw Pact" =) but, nevertheless, unnamed floppy disks may well have quite visible traces leading to the manufacturer. ...

Re: C128 dcr & EGA color display

Regarding the 1571, the maximum MFM disk capacity that the drive can handle is 340kBytes (in total), ahh... sorry... understand... i simply forgot what 1571 is a double-sided version of 1541 - i.e. 40 tracks on the one side as maximum. and - because of 35 tracks on one side limit we have 70 tracks ...
