(5.1) Cybermaxx Headset Web Page at Halted Specisalties http://www.halted.com/online/cybermax.htm
Particularly useful information from Nate Caine's Cybermaxx page:
(5.1.1) Chips used (IR3y05, MN83803AK)
(5.1.2) IR3y05's gamma correction function
(5.1.3) Design flaw in Cybermaxx I, where alternating horizontal scans from one eye to the other subverts the function of the IR3y05's switched inverter, potentially harming the LCD
(5.1.4) Logic diagram of LCD design: reveals much about its functioning and timing signal requirements
(5.1.5) Cybermaxx system connection diagram
(5.1.6) General description of the Cybermaxx's design, including its head-tracking system
(5.2) Verbal description of the LCD's timing control registers and timing protocol
(5.3) Information on the Cybermaxx's power supply setup, including the use of elevated ground to get around 14 volt supply using 7812 3-terminal voltage regulator chip for IR3y05's VCC2.
(5.4) Advice on soldering techniques.
