I have a couple of Q*bert PCB's that I am working on.
This one in particular has some funky graphics that follow certain characters around. They each have a letter or symbol attached to them.
2 characters have White "W's" and 1 character has the large, yellow "Q"
I re-programmed all of the ROMS. (Had some bad original ROMS and replaced them which fixed a lot of other bad graphics including the 2 white blocks shown under the "Change To")
I installed a new Processor.
I do not see any corrosion or damage on any of the sockets when I removed the EPROMS and Processor but do know that these older sockets can get funky over the years.
I am just trying to see if anyone has experienced this particular issue and can point me in the right direction before more extensive troubleshooting has to be done.
Thanks
