Here is my file with the DELUA info. Feel free to edit/store this at any
archives.

Settings for a DELUA: (M7521, single board Ethernet interface)
Address selection, Switch at E106, Sw1 -> A12 ... Sw10 -> A3; switch on is
a zero for the address bit.
Def: 774510 => (1) FFNNFNFNNF (10)
Vector selection, Switch at E69, Sw4 -> V8 ... Sw10 -> V2; switch on is a
zero for the vector bit.
Def: 120 => (4) NNFNFNN
(default address for first DELUA is 774510/120, secondary would be 760460/400)
Boot option, Switch at E69:
2 3
N N Remote boot disabled * def for VAX
N F Remote boot from boot ROM
F N Remote boot and system load
F F Remote boot disabled
(there is no default for a PDP-11)
Switch E69 position 1 is used for Loop Selftest: continuous selftest when
on. (power-up starts test.)
^^ (off? -- JMBW)
The only jumper appears to be the priority plug.
^^^^^^^^ ^^^^ (what priority plug? -- JMBW)
To achieve loopback on the AUI, you can connect AUI pin 3 to 5; and pin 10
to 12.
