I'd be interested in feedback from anyone else who has actually put an IBM standard floppy in their PC. Not only did I try a known-good drive from my 6300 and play with all the jumpers, but I ask an AT&T serviceman who verified that the 7300 floppy was NOT PC compatible. However the Teac drive in the 7300 is Teac FD-55B-01-U which is one I recall as marketed for MSDOS clones. The jumpers could certainly have been the problem - the naming schemes of the two letter codes on the jumpers was not the same between the Teac 7300 and the 6300 floppy drive, so I was just guessing and experimenting. Maybe someone knows the changes from a standard clone floppy setting? Also, if the drive is really PC compatible, does that mean that an after market 3 1/2 inch or an AT drive could be substituted? Or would that be beyond the abilities of the controller to handle? -- Steve Spearman {ihnp4,ethos}!ihop3!spear Voice: (312) 979-4181
