4 SID Midibox in the making pics
Following a thread on the MIDIbox forums, a user named ludo has been posting in the last months some interesting pictures of a 4 SID MIDIbox in the making.
"...way back in october I got my "Step 1" mbsid working; LCD, 5 buttons, and a 6581R1 sid making some sounds. Since then, off and on because of travel for work, I've:
-Built up all 3 slave modules
-created a 'optimized C64 power supply'
-programmed successfully each PIC with header and corresponding mios with device IDs 1-3
-programmed each slave PIC with correct type of SID app, i.e. IDx1 and IDx3 for 8580 and IDx2 for 6581
-created a full control surface from an old C16 case, a C64 motherboard as panel, and lots of drilling
-tested all of the buttons and LEDs for correct wiring
-confirmed all voltages to be correct for each module
-the 6581's have 12 volts
-the 8580's have 9 volts
