So I acquired all the parts for my MB6582 years ago. Very slowly I assembled the base plate and then got into some problems during the checks I believe. Now after years of collecting dust I want to finish it off and get that awesome sound out of it :happy:. So this thread will probably be a debug/build/progress but also at some times a cry for help thread :P.

So lets get to it. This is how I found it. Directly did the testing described in the MB6582 build guide.

  • No Shorts between GND and Voltages

  • SID's pin 25 are all connected to 5V and all pin 14 to GND

  • Core's pin 11 are all connected to 5V and all pin 12 to GND

  • 6N138 is connected to 5V and GND

And now the trouble starts:

On the 74HCxxx all pin 8 got to GND so that is good.

But there are 3 problems on the pin 16 to 5v though. Looking at the picture you would already have guessed it, they are at U3_SID1, U4_SID2 and U23. So it is time to heat up the soldering iron and resolder those pins I guess.

Comments are welcome and hope show you more progress soon.
