2-5 Installing Memory Cassettes
Caution Be careful to always turn the power off before inserting or removing a Memory Cassette. If a
!
Memory Cassette is inserted into or removed from the CPU with the power on, it may cause the
CPU to malfunction or cause damage to the memory.

The program is written using a PROM Writer. The ROM is mounted to the
Memory Casette and then installed in the CPU. I/O data cannot be stored.
An optional Memory Cassette can be installed in the C200HS. (The C200H
Memory Unit cannot be used with the C200HS.) The two types of Memory Cas-
settes are described in 2-4 Memory Cassettes. To install a Memory Cassette,
follow the procedure outlined below.
1. Set the DIP switch. For an EEPROM Memory Cassette, set pin no. 1 (write
protect) to either ON or OFF. Setting it to ON will protect the program in the
memory from being overwritten. Setting it to OFF will allow the program to
be overwritten. (The factory setting is OFF.)
For an EPROM Memory Cassette, set pin no. 1 (ROM Type Selector) ac-
cording to the type of ROM that is to be mounted.
Pin no. 1

2. Write to EPROM (if using an EPROM Memory Cassette). Using a PROM
Writer, write the program to EPROM. Then mount the EPROM chip to the
Memory Cassette, with the notched end facing upwards as shown in the il-
lustration below.
