and used for storing data.
The program is written using a PROM Writer. The ROM is mounted to the

2-3 Expansion I/O Racks
The Backplane used to construct a CPU Rack is also used to construct an Ex-
pansion I/O Rack. An Expansion I/O Rack is identical to a CPU Rack, except the
CPU is replaced with a Power Supply. Two Expansion I/O Racks can be con-
nected to a CPU Rack. The number of I/O Units and Special I/O Units that can be
connected to an Expansion I/O Rack is determined by the number of slots on the
Rack.
