Keylock

The keylock on the front panel allows you to disable the

keyboard and RESET button and lock the top cover of the

main unit for security. The keyboard may be locked while

the system is in operation. This disables the keyboard SO no

one can interfere with the current operation.

To lock the system, insert the key with the notch pointing

left and turn it clockwise. You must press it in slightly when

you turn the key. To unlock it, insert the key with the notch

pointing up and turn the key counterclockwise. You can

remove the key in either position.

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.

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.

Installing Floppy Disk Drives

Software Problems

---

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.

--_

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.
