JUMPER # DESCRIPTION
W2 Jumper W2 ties the power-fail non-maskable
interrupt request (PNMI*) or the frontplane
interrupt request 5 (FP5*) to the interrupt
request 5 (IR5) on the interrupt controller,
depending upon the state of jumper W9.
Factory default installs this jumper.

IN † PNMI* or FP5* may drive IR5
OUT Alternate source may drive IR5
W3 Jumper W3 ties the STD bus pin INTRQ2*
(previously CNTRL*) or frontplane interrupt
request 6 (FP6*) to the interrupt request 6
(IR6) on the interrupt controller. The state of
jumper W10 decides between these two
possibilities. Factory default installs this
jumper.
