Dropcheck Posted December 26, 2018 Share Posted December 26, 2018 Aside from the obvious physical dimensions what is the difference between a SF314 floppy drive and an industry standard 720k drive? Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted December 26, 2018 Share Posted December 26, 2018 ? I don't see diff. in physical dimensions. And I'm not sure that there is something like "industry standard 720k drive" . I use in last years floppy drives which are not made for Atari computers. Simple reason: they are made after Atari era. And that means that I know differences well: 1: PC floppy drives - let's call them so, because most is made for PCs, have default setting to act as floppy B . The reason is twist of lines of PC floppy cables. In Ataris no cable twist, and drives need to be set as A (logical 0) . Talking of course about first (and usually only) drive . Another, and practically last one relevant diff. is write protection : See this page: http://atari.8bitchip.info/flomodam.html Of course, there may be differences in shape of eject button, and even in color Ah, and most of 3.5 drives in last 27 years is not 720 K, but 1.44 MB - well , on later Ataris that can be 1.6 MB too Quote Link to comment Share on other sites More sharing options...
+poobah Posted December 27, 2018 Share Posted December 27, 2018 Aside from the obvious physical dimensions what is the difference between a SF314 floppy drive and an industry standard 720k drive? The DS0 and DS1 jumpers, that's pretty much it. Quote Link to comment Share on other sites More sharing options...
oracle_jedi Posted December 27, 2018 Share Posted December 27, 2018 Pin 34 (READY) isn't used by the SF314/SF354 drives. That can confuse a disk controller expecting the ready line to be asserted. Quote Link to comment Share on other sites More sharing options...
