see pics, I get the ampersands and no beep from the speaker.
Things I've tried:
Different power supply
gently pulling all accessible chips up and reinserting
replacing CPU chip
Also I replaced all the Roms from another board because 3 of the roms had rusty pins that broke off.
would love to get it working but no matter what I do I get the same powerup screen so there must be a bad chip or memory.
Should I try replacing all the memory or a different approach?
