This bulletin is intended to provide the results of compatibility testing conducted
by the Computer Product Support Center with the MUX Adapter card, the High
Density Controller card and the 3.5” 720KB/1.44MB external floppy drive from
Manzana Microsystems.
The MUX Adapter card was found to support the external floppy drive as a
720K floppy drive in the Equity I +. The instructions should be followed as
described in the MUX Adapter Card Manual, supplied by Manzana. No
alterations or special accommodations are necessary. Jumpers on the card
should be left at the factory default settings.
The High Density Controller card was found to support the external floppy
drive as a 1.44Mb floppy drive in the Equity I +. The instructions should be
followed as described in the High Density Controller manual. No alterations
are necessary.
The High Density Controller installation requires that the Equity I +‘s built - in
floppy disk controller be disabled. This is done by setting J1 on the Equity
I + main board to the “B” position.
The 380KB floppy drive A: is then
connected to the High Density Controller, instead of the internal controller.
MS - DOS version 2.X or higher is required for installation of the High Density
Controller and use of the external drive as a 1.44MB floppy disk drive. The
Equity I + is shipped with MS - DOS 3.3, previously version 3.2.
Manzana includes the 3Five disk utilities with their MUX Adapter card and High
Density Controller card. These utilities include a device driver for the 3.5”
floppy disk drive, a format utility and information utilities for use with the
external 3.5” floppy disk drives.
