Apple Lisa MacWorks II PFG Instalation

Follow the Apple Lisa Disassembly Guide to remove the Lisa's real panel.

Remove the Lisa's Card Cage.

Remove the Lisa's I/O Board. The I/O Board's clips are marked in red.

Release both clips holding the I/O Board.

Pull the I/O Board up to remove it.

Remove the chip marked 8530 at location 9D.

Next to the chip removed in step 3 is a crystal. These are not always installed with a plastic coating. The crystal shown in the image is insulated.

If your crystal is not insulated then tape a small piece of cardboard on top of it.

Ensure the pins on the MW+II PFG (Programable Frequency Generator) are perfectly straight. If they are not then slightly bend them into place.

Insert the PFG into the 8530 socket.

Locate the chip marked LS132 located at 6A.

Connect the Red and Black wires as shown in the second image on this step.

It is best to place a piece of electrical tape on the wires to help hold them in place.

Replace the I/O Board back into Lisa's Card Cage.

Replace Lisa's Card Cage Back into the Lisa.

Replace the rear panel on the Lisa.
