Parity RAM lnstallation
The Equity I+ supports parity RAM checking to insure that
the data stored in memory is valid. To install this option,
insert two 50256 or 51256 chips in sockets 6M and 7M; and
4164 chips in sockets 6N and 7N. Then set jumper J2 as
shown in the table above.

lnstallation/Support Tips
Power
The Equity
If
has a power supply that is switchable
between 115 V, for US 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.)
Power
Inlet
/
RS232C
Serial
port
WARNING! The voltage is not changed between the AC
inlet and the AC outlet. If the CPU is switched for 230 V in
order to function in Europe, only peripherals certified for use
at 230 V should be plugged into the outlet.
Video Adapters
--- When using the Epson MGA video adapter in
conjunction with a monochrome monitor with the
Equity I+, set DIP switches 2- 1 and 2-2 both
OFF. This will define the parallel port as secondary
and avoid conflict with the address for a parallel
port on the video adapter. The port itself is not
installed on the adapter, but the address is in use.
--- When using an EGA or VGA video adapter in the
Equity I+, set DIP switches 1 -5 and 1 -6 both
ON.
Installing Floppy Disk Drives
-
When installing a floppy disk drive as drive B,
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.

12/12/88
Installing Hard Disk Drives
-
If you are having difficulty in formatting the hard
disk drive, try starting over with the Unconditional
Format option in diagnostics.
Third Party Option Boards
--- If you find that some third party option boards do
not function properly in the Equity I+ at the higher
speed, try setting the CPU speed back to 4.77 MHz.
Software Problems
--- When installing a copy - protected software package
on the Equity I +, set the the CPU speed to
4.77MHz. 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 I+, try switching the
CPU speed to 4.77MHz before giving up. Some
software packages (e.g., Disk Optimizer from
Softlogic Solutions) have been found to function
only at 4.77MHz.
