Poor documentation

The maintenance manual for this (which I have on fiche) has a number of major gaps. Things I wanted to include here, but couldn't find, included:

  • a list of all the cards
  • locations for them all in the backplane (except the per-line cards, which it does give)
  • the maximum baud rate supported
  • whether the 303 interface uses 20mA (like the DU11)

The DS11 does have one oddity: the interrupt priority level (BR4-BR7) is set in the CSR, not by a plug (like every other UNIBUS device I can think of). 15:52, 19 November 2023 (CET)
