Couldn't find the manual for the M8743, but I managed to dig up the manual
for the M8722, MS11-M. Let me know if you want the settings for this
board instead.

I looked really hard on our internal network for an electronic copy of
this manual but I couldn't find it so I'll try to make an ACSII drawing of
it..

Switch pack E11:
[Use 1-6 on the switch pack to set the vector]

    off off               300
    off off         off   310

Note: Switch OFF produces logical "one" on the Unibus    .


W1: Normally in. Out disables master clk for factory testing.
[W1: Jumper just above switch pack E72]
