6.3.9  High Resolution Module (HRM)

The second video output module is the High Resolution Module. The High Resolution
Module only supports the 2K x 2K resolution. The High Resolution Module requires two
Video Memory Modules. The High Resolution Module does not provide console support.
A second console is required in the high resolution PowerStorm 1000 subsystem. The
block diagram for the High Resolution Module is shown in Figure 6-6.
