Why? I have examined the memory cards. The C-D (actually, C)

The only -11 that complains if the grant chain is broken that I know of is
the /34 (maybe the /04 too). I certainly have a QBUS chassis right next to my
workstation here that i) has a bunch of empty slots, and ii)
Most Probable cause is interrupt grant is broken. For most microspheres

As far as I know about the 11/93 (or 11/94), all memory is on the CPU module.
The 11/9[3|4] is sort-of an 11/8[3|4] with all (PMI) memory on the CPU module
as the cache on the 8[3|4].
The 11/9[3|4] with 2 MB RAM can only be upgraded to 4 MB by adding RAM chips on
the CPU module.
