I used to work with an engineer whose first job out of school was 
writing for those books for Osborne.  He thought his efforts were 
pretty terrible, but I assured him that there was enough information 
there for most to draw their own conclusions.

Does anyone know of ready sources for the TMS9900 and 9995 chips
