there is a cpu.h in one of the other Ultrix 1.0 disks:

...
union cpusid {
...
         struct cpu780 {
                 u_int   cp_sno:12,              /* serial number */
                         cp_plant:3,             /* plant number */
                         cp_subeco:4,            /* sub-system-rev */
                         cp_eco:5,               /* eco level */
                         cp_type:8;              /* VAX_780 */
         } cpu780;
	...
}

...

#define VAX_780         1
#define VAX_750         2
#define VAX_730         3

#define MVAX_I          7
#define MVAX            8

let's me hope that there is some 11/780 stuff in there...
