The C2000H Simplex System is a PC that operates with only one CPU. The op-
eration of the Simplex System is quite similar to that of the C1000H, in that a
maximum of seven Expansion I/O Racks can be utilized to access a maximum of
2,048 I/O points.
One difference can be seen in the CPU Rack. Only six I/O Units can be mounted
to the CPU Rack of the C2000H Simplex System. Also, an I/O Remove Unit, a
feature unique to the C2000H Systems, can be mounted to the CPU and Expan-
sion I/O Racks to allow on-line exchange.
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 pro-
gram into the RAM Pack or you can copy a program that has already been writ-
ten 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 memory required for your application, choose either two chips
for 16K words or four chips for 32K words. Only one model of EPROM chip can
be used in the C1000H and C2000H PCs. 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.
The table below summarizes the programming capacity.

the SW1 switch for
either 16K words or
32K words.
