Kevin on the Simple DIY Electronic Music Projects blog received a non-working 1985 Yamaha DX100 synth.
My thinking here is that as it is a pretty nice synth with most of its functionality on a single PCB with connectors to the peripherals, if all else fails I could stick a Pi inside and turn it into a DX100 shaped MiniDexed DX7!
But I’ve decided to have a proper look to see if I can do some “proper” digital electronics fault-finding for once to see if I can get anywhere.
Armed with schematics and other documentation, Kevin goes through the diagnosis.
Here is another repair video Kevin references in his resources.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
