The indication is a bad or loose RAM chip in the Bit 6 position. The RAM chips are in Row F at the front of the motherboard starting with Bit 0 and running to the right when viewed from the front of the computer. | Row | E | Bit 0 1 2 3 4 5 6 7 | | _ _ _ _ _ _ _ _ | | Row | | | | | | | | | | | | | | | | | | F |_| |_| |_| |_| |_| |_| |_| |_| | | IC# 6 7 8 9 10 11 12 13 | |______________________________________________________| Front of Apple IIe If your RAM chips are in sockets, try removing and re-socketing the second chip from the right. If this does not work or if your chips are soldered in place, the chip is probably bad and will need to be replaced.
