• Without the screws, the lid is not connected to the bottom of the chassis, but many wires connect
between the two sections. Carefully lift the front of the top section and place the back of the top section
under the back of the bottom section as shown. Prop up the lid, using something like a drumstick.
Install the new ROM chips
Now that the chassis is open, the remaining steps are identical for the MPC60 and MPC60-II. However,
the instructions are different if you have the Marion Systems MPC-SCSI upgrade installed. Instructions for
both are shown below.
If your unit does not have the MPC-SCSI upgrade
installed
The diagram to the right shows how the inside of both
the MPC60 and MPC60-II appears. The following
instructions refer to that diagram.
• Locate the 4 existing ROM chips in their sockets.
Before you remove them, write down which chip goes
in which socket in case you want to reinstall the old
chips later. To remove the old chips, carefully insert a
small blade screwdriver between each chip and its
socket on one end and very gently twist the
screwdriver to pry the chip up a small amount. (Don’t
insert the screwdriver between the socket and the P.C.
board as this will remove the socket!) Then, do the
same thing on the other end of the chip and again pry it
up a small amount. Do this a little bit on each end a
few times until the chip is removed from the socket. Repeat
this process for the 3 remaining chips.
• Find the 4 new ROM chips supplied in this kit and remove
them from the shipping tube. First, very carefully bend the
pins on each chip so that the 2 rows of pins are parallel to
each other. (See diagram below.) This can be done by
