There should be sufficient information for MESS emulation.  I think that 
what CD-i support there already is in MESS would be a good start.  Most, 
if not all, of the chips in the MM/1 are also in other machines already 
emulated under MESS, and we certainly have the logic equations for the 
PLDs on the I/O board and 8M memory board, as well as schematics.

If you want to read up on the Signetics 66470 VSC, the databook is at 
http://www.mess.org/datasheets/philips
The MM/1 Technical Manual is available here and elsewhere: 
https://ia801707.us.archive.org/11/items/MM-1_Technical_Manual_1991_Interactive_Media_Systems/MM-1_Technical_Manual_1991_Interactive_Media_Systems.pdf

It's also here, along with more documentation:

And I believe much of it is on Maltedmedia as well.  Here are some 
things I scanned in 2008:
