7092c55907 VAX750: Fixes to Unibus adapter to address #346 
Modified the UBA750 simulation, incorporating these comments. Ultrix
appears to access the non-existant datapath registers and given that this
works on the real hardware the most likely option seems to be read 0
and write NOP. I think this will be true for any access to the UBI outside
of the known registers.

c94edb6b2d VAXStations: Improvements and bug fixes to keyboard and mouse devices 
Whilst working on a new video device I ran into a few problems with the
LKxxx keyboard and I noticed there are already some open issues against
the keyboard and mouse devices. These changes should resolve #320 and
may help with #272 (although I think that is an SDL issue). I've tested these
changes with VWS, UWS and DECwindows with both captured and
uncaptured input modes.

a719ef51e8 alpha: Fixed function field widths (Maurice Marks) 
Maurice Marks, at VMS Software Inc, is using the Alpha instruction emulator
from SimH as a backup to an Alpha binary translator! He found a bug in the
instructions definitions: function fields, both integer and floating, are 7b not
6b.

c97f466457 PDP8: Annotate fall through paths in switch statements 
The code is a bit difficult to understand, but it represents the 'normal'
path for processing a DECtape word. The code always flows all the
way to the break.

For start of block, there's extra code to check for a timing error; but
then the first word is processed (case 0).

For a normal word, a 3-cycle data break is done - increment word
count and current address, check for word count overflow, put the
word in the buffer; but then check for end of block (case DTO_WCO).

If the word count has already overflowed,  just check for end of block.

So yes, the end of case 0 should be labeled 'fall through' as well.

FNC_WRIT has the same structure and needs the same comment.
