Repairer: channelmaniac

Symptom: Dead

Phoenixed the Q-Sound board and the C board. Replaced the 8 1Mb EPROMs on the ROM board (B board) with 2 4Mb EPROMs containing the phoenix code.


Symptom: Board crashes with Address Error at FFFF8F68

Board had "PSE" version code on 8 1Mb EPROMs and not "PSU" code. The phoenix code is based on PSU ROMs and mixing the ROMs resulted in the error code.

Replace the 8 1Mb EPROMs with 2 4Mb 16 bit EPROMs with the 16 bit version of the Phoenix code to resolve this error.


Symptom: Dead. Board suicided.

Replaced the ROM on the QSound board with a 27C020 programmed with the phoenix code. Modified board to use the code. Modified the C board and reprogrammed 5 EPROMs on the B board with phoenix code and replaced 3 slow EPROMs (Replaced 175ns with 120ns) to finish resurrecting the game.


Symptom: Dead

Replaced 5 slow EPROMs with proper ones programmed with suicide free code. Modified the C board and Q-Sound boards. Replaced the 27C010 on the Q-Sound board with a 27C020 programmed with suicide free code.
