HI!
I've been working on a couple of SF2 boards that I got that were dead. I've got one back to perfect as it just had some bent under pins and needed some new roms chips. But the other one has been the problem!
After lots of testing with good parts I've got it down to just 2 chips. The PALs on the B board located at 11D and 12D. They are listed on the board as PAL16L8A. Once I determine which of the two or may be both are the issue, how do I go about replacing these? I have no idea how to burn a PAL and if you even can. Do I need to get working ones from another SF2 board? I checked jammarcade.net to see if there was a dump but didn't find anything for those chips there, only the PAL at 1A.
I've hit a wall here, can anyone help me out??
