So, I think I've jumped it to A mode, no turbo on I or II, and no slow motion. I've been playing around with it some more. If I ground out the Run input, then buttons I and II work properly when grounded to GI or GII. Otherwise not getting any response. (and I don't have a 47k ohm resistor laying around, oops, so that's why R2 is a cobbled monster) |

Maybe a better pic... |

There’s another schematic floating around but I’m not sure he ever got it fully working |
| mourix:
The jumpers are correct as you stated. Sanity checks: * I don't see all the solder joints flowing to the top. Are they all soldered down properly? * Did you put 100pF at C6 and not accidentally 100nF? * Are the 9 pin resistor arrays the right way around? |

Common pin is at the top on RN1 and RN3. On the bottom of RN2. I’ll double check the soldering and C6 value. :cheers: |
