For completeness, we describe the following commands that are
available only during the programming mode of the Model 3377’s
internal Xilinx logic chip. These enable the mode to be set by selecting a
firmware program from the 4 that are installed in the EPROM, or loading
a different program from CAMAC. For these commands, the A lines are
not decoded, they are simply ignored.
