The toggles are set to program the PROM and compare. No compare error display indicates the
PROM has been programmed with the data displayed from memory.
The third four bits of each word of memory can be programmed into a PROM
u~ing
the
following commands to get the control information for memory from cassette and set toggles to
program PROMs and compare. A new PROM should be inserted before each programming
process is initiated .

11.3 EXAMPLE 2
This example loads the memory data from the first PROM programmed in the previous example,
and uses this data to program another PROM. The first step is to define the memory and PROM
data configurations to be used in the transfer from PROM to memory and then from memory to
PROM. The keyboard commands are used· for tutorial purposes in this example to set up the
data configurations instead of using the control information on the Standard Control Infor-
mation Cassette. The keyboard subcommands needed to define the same information found on
the Standard Control Information Cassette are MI, RI, SW, and RC. The memory and PROM
bounds are defined with the MB and RB subcommands.
