It had a different key (which was always an option from DEC, but few customers chose to pay for it) but I don't recall what the code was. The PDP-8/L itself was already partially stripped and had mechanical damage to the chassis and backplane when I bought it, so it was always a parts donor (the other one from that day is still in my collection and is functional). -ethan
