NOTE: All Cores (PIC Rx pin) are connected to the MIDI In port. The different device ID (0,1,2,3) on each PIC determines which PIC receives an upload, J11 is used to get “feedback” from that PIC during the upload.

The absolute bare minimum headers you should put in are:

• J11 (for switching which Core is connected to MIDI Out)

• J15_CORE1 (for master Core’s LCD)

• J3_SIDx, J23_SIDx (for connecting feedback pots, or at least grounding the SID audio inputs) 

Then the list of useful headers for a “default” MB-6582 setup (no expansion port usage):

• J70 (for passive mixed output, to connect to headphone jack) 

• J2 (for power LED) 

• J25 (~9V-11V DC, for connecting to fan) 

• J3 (5V DC, for connecting to fan, if 9V-11V makes the fan too noisy) 

• J1_SIDx, J2_SIDx (for voltage switching between 9V and 12V per SID, see PSU Option B and D) 

Then for the advanced users, perhaps wanting to connect things via the expansion port:

• J6_COREx, J7_COREx (for analog outputs via AOUT modules) 

• J5_COREx (for analog inputs)
