I would be curious as well, as it is implied that the $ff1x and $ff3x 
are not immediately useful (the $ff0x and $ff2x decoding is incomplete 
on board the Coco3, so they also are active for $ff1x and $ff3x, as the 
memory maps note)

I'd also be interested in the RAM and ???, though I assume one of these 
is the "nothing selected" option, since the '138 is always on (well, 
SLENB can disable it, but GIME cnanot assert SLENB)

I can say there would be some value in someone who could combine GIME, 
GIME2, LOMONT, Service Manual, Sock's GIME registers, etc. into a single 
locaiton with a common layout.  As someone trying to get familiar with 
the platform, it is difficult to sort through the various resources to 
get to consistent and accurate data.  I see now where Darren picked up 
his list from (it's listed on 2 lines on GIME.txt),
