Hi,

Missed one,  There is one toshiba memory IC (narrow one) next to this 
EPROM.  I'd change this SRAM first.

Did you do the finger check for thermals?  I once fixed a ATI Wonder 
800 this way, was a 74xxxx.  One was just warmer than others.

By the way, this type of PAL ICs tend to fail often and run hot. 
(MMI)

Cheers,

Wizard
