Fixed - Tron sound question - Which LS191 chip is which channel?
I've been working on getting my Tron working. So far I've fixed fuses, added a switching power supply from Arcadeshop, capped and adjusted the monitor and capped the audio amp board. But I still have problems.
- Sometimes I'm missing channel 5 and sometimes I'm missing 4,5, and 6.
- Sounds are barely audible in attract mode.
- Some sounds are missing (maybe because they are on channel 5).
My first guess is that the LS191 for channel 5 is dead since that channel never works. I'd like to replace that chip instead of shotgunning all six.
The schematic shows six 74LS191 chips, one for each of the 6 channels but I can't find anything on KLOV which says which is which. Does anyone know which chip is channel 5?
I also have replacement 4016s. If I knew which channel was #5 I could replace the 4016 in that chain as well.
