Thanks for all the replies!
It turns out the problem was that the multiplexer box was drawing less than
30 milliamps. We inserted jumper J1800, and the Sun-4 now communicates
quite well with the outside world.
Turns out the problem was described in one of the Sun's "Read This First"
manuals. Too bad there were *several* manuals bearing this banner...
Again, thanks for the pointers to the HW "Read This First" manual.
