3-6 Installing Memory Cassettes
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 2-2-6 Memory Cassettes. To install a Memory Cassette,
follow the procedure outlined below.
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.
1, 2, 3... 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. Even if a 27512-type chip
is mounted, the usable capacity is still only 16 KB.
Pin no. 1 ROM type Model Capacity Access speed
OFF 27256 ROM-JD-B 16 KB 150 ns
ON 27512 ROM-KD-B 32 KB 150 ns
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.
