How does the Sy/Max CPU write to the uv-prom chips?

When the program is complete, the last rung is the 'write to uv-prom instruction' which is mandatory for the CPU to go into RUN, The 'write to uv-prom instruction' is a straight line from the rail to a coil addressed 8176-16 (see below). When the program is loaded it will be saved and write protected. To make any alterations to the program, the uv-prom chips would have to be erased.
