Epson Equity 320SX PLUS - Manual (Page 39)

Setting the Diskette Drive(s)
Your system probably came with one diskette drive installed
and you may have another drive of a different size or
capacity. The SETUP menu offers five possible selections for
your diskette drives (A and B):
1.2MB 51/4-inch
360KB 51/4-inch
1.44MB 31/2inch
720KB 31/2-inch
Not installed.
Check the settings displayed for both drives and correct them
if necessary. (If you have only one diskette drive, select
Not
installed
for drive B.)
Note
If you do not know the capacity of your diskette drive, ask
your dealer.
