Step 1 :: Disassembly

• Follow the Apple Lisa Disassembly Guide (https://www.ifixit.com/Guide/Apple+Lisa+Disassembly/117991) to remove the Lisa's real panel.
• Remove the Lisa's Card Cage.

Step 2 :: Remove I/O Board

• 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.

Step 3 :: Removing the 8530 Chip

• Remove the chip marked 8530 at location 9D.

Step 4 :: Crystal Insulation

• 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.

Step 5 :: Installing the Daughter Board

• 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.

Step 6 :: Attaching Red and Black Wires

• 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.

Step 7

• 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.
• MacWorks + II (MW+II) floppy images can be found here (http://macintoshgarden.org/apps/macworks-plus-ii).
• The MW+II manual can be found here (http://mirror.macintosharchive.org/macintoshgarden.org/files/manuals/MacWorks_Plus_II_Manual.pdf) which includes detailed instructions how to instal thel MW+II software.

Conclusion

MW+II supports Macintosh System Software up to Macintosh System 7.5.5.
Supports over 10MB of RAM (more than 4MB requires an XLerator.)
