The highlighted yellow letter indicates the currently displayed register type. The register types that are
selectable are marked with a highlighted white letter.
At the end of the register area there are two fields that are used to alter storage (address and data). They
are selectable through the highlighted white letters “R” and “D”. Pressing “R” allows it to specify the sto-
rage address to be updated. The default address is x’00000000’. Pressing “D” allows it to enter the data
to be updated at the specified address. To place the new data value at the specified address press “O”.
The display refresh rate of the register area is depending on the PANRATE setting. This may be anything
from 1 to 5000 milliseconds (between 0.001 and 5 seconds). The default refresh rate is 500 milliseconds.
Please note that a fast refresh rate may negatively impact the performance, beneath the fact you won’t be
able to read anything in the register area.
4.3.4 Operator Area
The operator area displays the current Hercules MIPS and I/O rates and has eight controls that can be
selected through the highlighted letter of their respective label. These controls are:
Figure 10: Device and Status Panel – Operator Area
For several of these controls you will be prompted to confirm the function. IPL requires specifying a de-
vice through its prefixed letter as shown in the peripherals area. If the IPL device is not within the first 26
devices then it has no letter assigned and the IPL must be performed from the console panel through the
regular “IPL” console command.
