The main board is disconnected. I tested it and had both 12v and 5.33v with just the power supply section completed but now that I've finished the remainder of the IO board I lost the 12v. I've looked for anything obvious and found nothing. My solder work is very clean and I couldn't identify any errand traces or overlapping solder joints.
Any thoughts on obvious points to look would be a great help. I have looked for but haven't found a reference diagram for the IO board operating voltages so I'm not sure which traces are 5v, 5.33v, and 12v. If someone has a diagram or a overall schematic of the XOX they can post I'm sure it would be a help to the community.
With the IC out of the socket at the IC23 location I have voltages as follows:
Pin 1 0v
Pin 2 0v
Pin 3 .10v
Pin 4 0v
Pin 5 5.33v
Pin 6 .10v
Pin 7 .10v
Pin 8 31v
Wall wart voltage measures 12VAC (it is a 9VAC supply).
I'm waiting on new 78L06 and LM336 components for my second supply which with any luck will be here tomorrow and I'll have in the board and (fingers crossed) am hoping that one will work. I'll try to post some pics of the boards later.
