The toggle is set to display memory with the TS subcommand, and the display is printed when
the GO subcommand is entered.
Once the user verifies the data in memory, it is ready to be programmed into PROM. The toggles
to program PROM and compare memory and PROM are set with the TS subcommand. The
PROM should be inserted in the PROM Programming Module. The programming process is
initiated when the GO subcommand is entered .

The compare is successful, the PROM programming returns to the monitor, and the prompt
character (.) is displayed while waiting for the next command. If any compare errors are found,
they will be printed before the PROM programmer returns to the monitor.
The following printout shows a programming process in which compare errors were found .

To program the second four bits of each memory word into a PROM, a new PROM is inserted
and the following command is entered to get the needed control information for the memory
configuration from the Standard Control Information Cassette. The PROM control information
does not need to be changed as long as an SN74S287 PROM is being programmed .
