Spy Hunter Lives!

I've had this sitdown Spy Hunter cab since 1999, when IBM closed down the Taligent offices in Cupertino. The cab was apparently DOA for several months before I rescued it. After opening it up, I found one of the beer-can-sized electrolytic capacitors in the power supply block had blown-up, spewing sticky brown acid into the bottom of the supply. The failure sent a jolt which fried the Power Supply board, main CPU board, and toasted the monitor. It must have been quite a sight to whomever was playing the game at the time, probably a loud bang, and then plume of smoke.

I've been working on restoring it on and off (mostly off) for the last 7 years. I rebuilt the power supply with a switching PS and new harness, replaced the monitor flyback, horizontal transitor, and then recapped the monitor PCB. I aquired a used/working CPU board-set from another collector in San Francisco. But for the longest time, I just could not get the sound or controls to work.

So I decided enough is enough, and dedicated the last two weekends to finishing this project! I bought a new MCR Switching PS from wizzesworkshop and threw out my homemade harness, and sure enough I now had sound with battery backup as a bonus to save scores and analog calibration settings. There were still issues with half the sound effects being distored, and the analog board being dead. I must have swapped out every chip on the SSIO board before realizing the boards were from a standup Spy Hunter model, which has only 2 speakers, so the sound connector is different than my sitdown 4-speaker wiring. After rewiring the connector, sound was solved, although there is still a sizable hum coming from the switching power supply. I don't know why, but the analog controls magically started working after I realized the star-grounding cables were not hooked up to the dual amp boards. Unfortunally this did not fix the loud humming. Last thing was to replace 3 flurecent tubes and starters.

Anothing thing I discovered, is that the cabinet was made from parts of other cool arcade games at the time (apparently this is pretty common). Under the main flooring you can see graphics for a Star Wars upright. And inside the bottom of the seat, Discs of Tron. Both awsome games in their own right.
