B.3 M03 MEMORY MODULE EPROM UPGRADE
You will receive one EPROM (chip with label) to upgrade
the M03 memory module. The materials you will need
to supply are:
Phillips-head screwdriver
IC DIP extractor or a pair of curved needle-nose
pliers
1. IMPORTANT: Remove power from the unit by
depressing the power switch on the front of the
unit to OFF. Also remove power cord from the AC
outlet.
2. Remove the M03 module by loosening the 2
straight slot screws that attach the connector
board of the module to the chassis and then
pulling the module out.
3. Refer to the memory module mechanical layout
(see Appendix D.3) and locate socket U2.
4. Remove the existing EPROM from U2 with IC
extractor or needle-nose pliers. Gradually loosen
each side of the chip, alternating pliers from side
to side, so as not to bend chip pins. Pull loosened
the EPROM all the way out. Install the new
EPROM into U2. The EPROM is notched; the notch
on the EPROM should line up with the notch on the
socket. When installing the new chips, be careful
not to bend any of the pins. Make sure none of the
pins miss their sockets.
6. Re-install the module(s) and apply power to the
unit. The upgrade is now complete.
