View source for Talk:DS11 Multiple Line Synchronous Interface

==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)
