Denning is named after Peter J Denning, best known for pioneering work in virtual memory, especially for inventing the working-set model for program behaviour, which addressed disk thrashing and became the reference standard for all memory management policies.

Same basic hardware as Bell (more detailed hardware configuration there) but now has a nice SSD to work from.

Denning provides the following services:

The Beast Video Game Arcade System - emulation, display and control management.
Provide redundant fun and joy to those who play with The Beast

-Denning has a full height 8-port PCI video capture card installed to digitise the analogue cameras.
-The card is currently connected to the 3 yard cameras and the rear lobby camera. The other 4 inputs are disabled until we put more cameras up.
-The card is a BT878 8-chip 8-input full height PCI card similar to the [https://wiki.zoneminder.com/Kodicom_8800 Kodicom 8800]

-Each input is configured with:
-* fps: 10
-* alarm fps: 25
-* palette: BGR24
-* resolution: 640 x 480
-This might just about work with all 8 inputs, however, we may have to drop the resolution to 360 x 288 - realistically this may never happen as we have been opting to install IP cameras in the space - superior images and no complicated capture cards for image acquisition.
-== Issues ==
-Currently has only a single mechanical hard drive so vulnerable to data loss. There is space for a second hard drive if we want to mirror the drive.
