Floppy Drive

Is it possible to replace 5 1/4" floppy drive with a 3 1/2" drive?

Floppy Drive

Generally, yes. In detail, depends on the involved FDD generation and FDC capabilities. A few control lines of the
classical Shugart interface related to density switch and drive selection have been changed through the years. I guess,
you'll mostly get PC AT standard drives, they have less jumperable features compared to OEM versions. Hopefully,
they are working with your equipment as are, otherwise you have to study the interface more thoroughly, possibly
need to solder a jumper resistor or at worst case add an inverter to a signal.
 

Re: Floppy Drive

if the old equipment uses a PC compatible drive
is almost shure you can repalce the driver

just need to change connector
