There is still some
confusion regarding which
FDDs will work
with which Equity. Here is a quick reference for FDD selection
(for detailed information, refer to PSB Number S-0001).

1 -
This is the only FDD compatible with the Equity
I.
2 - This is the only 1.2 MB FDD compatible with the Equity
II.
One of the key issues is: NEVER USE ANY 1.2 MB FDD OTHER THAN
THE Q911A-AA IN THE EQUITY II!
The interface
is slightly
different from the AT "standard". As a result,
an AT-type
drive will work erratically (if at all). One of the problems
is a disk change error,
or continuing to use
the directory
from a previous disk.
Also on the Equity
II,
MS-DOS 3.2 does not allow sufficient
retries on diskette read/write with the Q911A-AA.
Consistent
"Abort, retry, ignore?"
messages
result
when attempting to
log a new disk.
Typically, "r" for
retry will overcome this
situation. MS-DOS 3.2 operation with the Q213A-AA is correct.
