Yes, Here is the latest schematic for rev 1,2 of the Issue VI. Note that this is not the same as the JMP or Martin replicas, it has an extra logic IC to allow ram at 0x200-7FF and optional support for 65X61 RAM chips, as well as having all the signals required for the VDU brought to the edge connector.
