IBM POWER SUPPLY IIGS INSTALLATION PROCEDURE

HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

These are the installation steps for this power supply and cable:

(a) Carefully unwrap the power supply. Use no knife or blade.

(b) With all power OFF, and after discharging any static, remove

the

present internal power supply -- a plastic clip at the keyboard end of the

motherboard holds it in.

Molex-7 connector on the motherboard.

(d) Use a DC voltmeter to CHECK THE VOLTAGES of the wires on the

Molex-7 plug (+5v, +12v, -12v, and -5v) before connecting to the IIgs.

[This

is an important precaution!] Some units require that a load (such as an

old

hard drive) be attached to a Molex-4 accessory plug to get accurate

readings.

With minimal load, voltages will normally be lower than the target values.

(e) Place the IBM power supply on the floor under the computer

table

-- position it so that there is no danger of objects (paper clips, pens,

etc.) falling off the table into a fan opening, nor of liquids being

spilled

into it.

(f) String the 6-wire cable up to the back panel of the IIgs, and

into

the computer.

(g) Carefully line up the Molex-7 plug with the male motherboard

connector. The two black wires are towards the keyboard-front of the

computer; the plug's "polarizing-ramp" faces towards the slots.

(h) Slowly push the plug onto the motherboard power connector.

(i) Put the lid on the CPU, then System Saver (if used), and the

monitor.

(j) Connect the power plug of the IBM power supply to your System

Saver IIgs (or to power strip). Continued use of the Kensington System

Saver

or AE Conserver is recommended to minimize heat that originates in the

motherboard or interface cards,

(k) Enjoy 150/200 watts of clean power in your Apple IIgs; say

goodbye

to crashes and freeze-ups attributable to low power!

INTRODUCTION

HHHHHHHHHHHH

Installing a high-powered (150-200 watt) IBM-style power supply

will

eliminate low-power problems suffered by Apple II users whose Apples are

loaded with accessories. You will now be able: (a) to add four or more

disk

drives, (b) fully populate all your RAM cards, (c) fill all slots with

large cards, (c) reduce overheating problems by having an external,
