PDP11 I/O page memory map

[Douglas Taylor via cctalk]

Is there a document that describes the bank 7 memory page and what 
addresses are reserved for what?  I think I've seen this before but 
can't seem to put my hands on it.

Another question, bootstrap is reserved for 173000, how many words are 
allowed there for this?  How do the more complicated bootstraps, e.g. 
microPDP11-53, accommodate this limitation?
