The schematic for a C64 RS-232 interface which was posted recently seems to have an error. It refers to a pin "O" on the C64 user port, but the reference manual labels them "A" thru "N", with no "O". What pin should this be? Are there other errors in this schematic?

I would mention that the Commodore VIC 1011A RS232 Adapter works just fine with the C64/128. Retail prices vary, but I understand you can usually pick one up for ~$15-30.
