 I haven't seen the FPF11, but mightn't it have different grant jumpers

Yes, it has a total of 12 jumpers.  All the ones that are "in" for
Unibus should be "out" for Qbus, and vice-versa.

Jumper:   W1  W2  W3  W4  W5  W6  W7  W8  W9  W10 W11 W12
Unibus:    R   R   I   R   R   I   I   I   I   R   I   I
QBus:      I   I   R   I   I   I   R   R   I   I   R   R

(I = inserted   R = removed)
