Default Re: 1978 Commodore PET project

Hm, that's a little bit confusing. We have diagrams for 320349 and 320351, but not for 320350. This from another forum:

"On the bottom of the board it says Part No. 320350 Rev E. On the top it says Assy No. 320351".
That makes it sound as though the part number for the PCB (only) is 320350 and the part number for the assembled PCB is 320351.

I think we'll assume your PCB corresponds to the diagram for 320351 (As AJ suggested) for the time being. Edit - just caught your update with the chip details.
