The complete pinout for 3/50 and 3/60 (it worked for my 3/50):
P3: 96 pin DIN connector
+5V: 1-25
+12V: 26-27, 90-91
GND: 65-89
-5V: 30-32, 94-96 (last three in top and bottom rows, closest to the power
supply side)
The Sun 3/75 and 3/1x0 need further lines (these are unused in 3/50 and 3/60):
-12V: 28-29, 92-93 (not used by Sun 3/100 CPU board)
Data: 33-64 ("P2" data lines)
Looking onto the backplane (from the back of the computer into the [empty]
chassis):

Some connectors are labeled with rows "a" to "c" instead:
1 -- 32 1 c -- 32 c
33 -- 64 <==> 1 b -- 32 b
65 -- 96 1 a -- 32 a
