Revive 11/34

[John Welch]

I also have an 11/04 that I went and drug out.  It is configured like this:

11/04:
........................   AAA BBB CCC DDD EEE FFF ....................
(Rear/Fans/Power Supply) 1 [M7263----------------] (Front/Keypad/DC ON)
........................ 2 [M7847----------------] ....................
........................ 3         [M7859--------] ....................
........................ 4 [M7847----------------] ....................
........................ 5             GNT ....................
........................ 6 [M7762----------------] ....................
........................ 7 [M7840----------------] ....................
........................ 8         [DILOG--------] ....................
........................ 9       {nothing} ....................
........................   AAA BBB CCC DDD EEE FFF ....................
I am thinking I could put a M9203/M7856 into slot 9, and find a M9312 
for slot 3 and maybe this would fire up.  Any suggestions?
