A&H GS3000 mpu problem
I have a GS 3000 console turn of the century stuff. The Mute mpu board has gone out part 002-347-1 so all the mutes seem stuck off and mute and status leds are stuck on. No LCD. Everything else works.
Need to find a replacement or figure out how to fix it. The pcb makes use of a P80C32 40 pin chip and what appears to be a 5v power supply.
Any ideas?
