Post by ramparts » October 24th, 2015, 12:24 am

Hi guys.

I have a mk1 bootleg2 pcb that only gives sound,and i traced image to this ic tms34010nfl.
For what i saw is a programmable grafics ic ,i get no horizontal sync frequency and i want to know if any chip sold on the net can be used to replace without any programming on the pcb

Best Regards
