Looking for 7704A - J290L (Power for Readout)

 

Could someone please point me to the schematic location of J20L on the Main Interface board for a 7704A? According to the schematic for the READOUT board, the cable for P34L (the power rail connection for the Readout Board) is terminated on the other end at P20L which plugs in to J20L on the Main Interface board but I cannot find J20L on the schematic for the Main Interface (or anywhere else). It is clearly shown on the picture of the Main Interface board (along with the grid location) and I know where J20L is physically on the board, etc., but I just cannot find it on the schematic.

Thanks,

Please excuse the TYPO in the subject line. That should read:

I hit the 9 key by mistake and didn't notice it until I saw the message coming back from the reflector.

Thanks,
