Installation manual

The process of keeping small parts in alignment will be much easier if you now place

a small piece of masking tape over the head of each screw and press it in place

against the cover, to prevent the screws from falling out during assembly.

Turn the plate over and slip one of the short, black plastic spacers over each of the

four threaded screws and down against the cover. Orient the USB Interface board

so that the multi-pin connector will face the rear of the keyboard (toward you,

during assembly) when installed. The USB Interface board has six holes. Using the

four holes which match your hard disk’s mounting pattern, slip the board, electronic

components facing up toward you, onto the four screws and down against the

spacers, which will support it slightly above the inside face of the cover.

Now slip the four longer spacers over the screws and down against the USB

Interface board. Only about 1mm (1/16 inch) of each screw will extend above each

spacer.

With its mounting screw holes facing downward and roughly aligned with the

threaded screw ends, but not yet attached, press the hard disk’s connector pins

into the short female connector plug attached to the USB Interface board (See

illustration below.). Now, working with one screw at a time, remove the masking

tape and attach the screws to the hard disk, evenly and firmly. Do not tighten any

until all have been started in the threaded holes, and then do not over-tighten

them.

Next take the USB cable, which you previously set aside, and again plug it into the

USB Interface board socket from which it was removed earlier, being careful that

the pins are correctly oriented; they are closer to one flat side of the plug than

the other.

If you have assembled everything correctly so far, when held in position over the

open plug-in board/hard disk compartment, the USB cable will extend from the

board’s socket toward the keyboard’s SIMM mounting compartment. The USB

Interface’s male connector pins will face the rear of the keyboard, or toward

where you are standing during assembly, when the keyboard is upside down.
