How to Install the
Memory Pack
! Caution
The CPU has a removable Memory Pack that stores the user program. Two
Memory Packs are available, in either RAM or ROM. You can write your own
program into the RAM Pack or you can copy a program that has already
been written to an EPROM chip and mount it in the ROM Pack. The EPROM
Chip must be mounted to the PROM Writer in order for the program to be
written to it. Then the EPROM Chip must be mounted to the ROM Pack.
Depending on the amount of memory required for your application, use 1, 2,
or 3 chips. Refer to Appendix B Specifications for specifications of the
EPROM chips.
Using the diagram and the table below as a reference, mount the EPROM
chips to the correct IC sockets.
