Can I use a normal 5.25" dsdd floppy drive with a
RQDX3, in place of the
twin drive RX50 unit?
Yes, but it'll generally be easier to find a DSHD floppy drive and hook
it up. But most/many DSDD's will work too.
Do a google search for "third-party-disks.txt"; it's a collection of
many years worth of experience on DECUSserve on this sort of use.
TEAC FD55GFR's are generally the most available and easily jumpered
for use. Many other brands lack even the drive select jumper.
