lnstallation/Support Tips
Power
The Equity Ill+ has a power supply that is switchable
between 115 V, for USA and Canadian use, and 230 V, for
use in other countries. The voltage switch is located at the
rear of the CPU between the AC inlet and the AC outlet (see
figure below).

WARNING!
The voltage is not changed between the AC
inlet and the AC outlet.
order to function in Europe, only peripherals certified for use
at 230 V should be plugged into the outlet.
Installing Floppy Disk Drives
- - -
When installing a floppy disk drive as drive 6,
remember to set the drive select jumper to the
second position and attach the pass -through
connector on the floppy drive controller cable to the
drive, not the end connector.
- - -
If the drive does not function normally, make sure
that the drive type has been correctly selected in
SETUP. Also check that any special drivers that
may be necessary have been installed correctly.

Installing Hard Disk Drives

- - -
It is recommended that a 16-bit AT -type hard
disk controller be used in the Equity Ill + . If you
must for some reason use an 8-bit XT-type
controller, select drive type NONE in SETUP.
- - -
If you are having difficulty in formatting the hard
disk drive, try starting over with the Unconditional
Format option in diagnostics.

Setup
When installing an optional expanded memory
board, do not list the memory under the memory
expansion option in SETUP. That option is for
EXTENDED memory ONLY.
- - -
If you are installing an EGA or VGA card, select
SPECIAL OPTIONS as display type in SETUP. This
holds true even when you are using a color or
monochrome monitor with these cards.
When installing a hard disk drive, be sure to consult
the drive type table (on page EQIII + -7) for the
drive type which fits the drive you are installing.
Third Party Option Boards
- - -
If you find that some third party option boards do
not function properly in the Equity Ill+ at the
higher speed, try setting the CPU speed back to 6
MHz or 8 MHz.
- - -
When installing a memory expansion option board,
make sure that it is a board capable of supporting
the higher bus speed (10 MHz or 12 MHz) of the
Equity Ill+. Some boards are rated for no higher
than 8 MHz.
Software Problems
When installing a copy- protected software package
on the Equity Ill+, set the the CPU speed to 8
MHz. This has been found to have fewer conflicts
with copy-protection. After the installation, the
CPU can be switched back to the higher speed.
- - -
If a software package does not appear to be
compatible with the Equity Ill+, try switching the
CPU speed to 6 MHz and/or 8 MHz before giving
up. Some software packages (e.g., Microsoft Chart
1.01 and Think Tank 1.001) have been found to
function only at 6 MHz and 8 MHz.
