SWITCHES AND JUMPERS
The CPU and Sound I/O Boards have several hardware variables that can be changed to adapt this assem-
bly to other uses. Jumpers activate circuit paths, and DIP switches select instructions.
Switches
There is one pushbutton switch on the CPU Board Assembly. It resets the CPU Board and restarts the 
game without turning off the power supply. There are two DIP switches on the Sound I/O Assembly at U12 
and U13. See Wiring Chapter for further explanation.
Jumpers
Jumpers control signals to other components in this game. These signals match production audio amplifi-
ers, speaker system, and video monitors.
Active circuit paths are factory optimized during the board test procedure. Leave jumpers in original 
positions to avoid program error messages.
Errors
The system detects errors at startup or during diagnostic tests and reports them on screen. The system 
automatically repairs errors such as minor disk data faults. Fix other errors, such as player control calibra-
tion, by manually resetting values in game memory. Gauntlet: Dark Legacy generally continues to operate 
(but with reduced performance) after discovering minor errors.
Record error messages before attempting to correct a problem. The USER MESSAGES report may store 
additional temporary messages (refer to STATISTICS earlier in this chapter).
After recording messages, turn off AC power, wait a few minutes, then turn AC power on. Pay attention 
to the startup screens and note any error messages during Power On Self Tests. If possible, enter the SELF 
TEST MENU SYSTEM and run all tests related to where errors occurred. Record and compare any new 
messages to the previous ones to determine whether errors are random or chronic.
SET RTC
NOTICE. 
Do not ignore error messages even if you can start and operate the game. Poor performance 
caused by playing games with errors may reduce earnings.
