A minimum BLINKY for the PDP-5, PDP-8, and PDP-12
-------------------------------------------------

LOAD ADDRESS x772

    x772: 7006 / RTL
    x773: 2771 / ISZ I .-2 / x771
    x774: 5373 / JMP   .-1 / x773
    x775: 7020 / CML
    x776: 4371 / JMS   .-5 / x771

    x=1 for 1KW memory (for a minimum PDP-5)
    x=7 for 4KW memory

[ For the PDP-5, you could change x772 to 7012 / RTR ]

LOAD ADDRESS x776
START / AC=0, L=0, IR=0

Almost all lamps are driven by this test!

On some models, this could be reduced to four words:

    x773: 2772 / ISZ I .-1 / x772
    x774: 5373 / JMP   .-1 / x773
    x775: 7026 / CML RTL
    x776: 4372 / JMS   .-4 / x772

Change x775 (and/or x772) for different AC effects.
