Dear customers,

   From the number of messages I've gotten about the "No such device
   or address" message, it is clear that Monitor doesn't know as much
   collecting MP CPU data as I thought it did. My apologies. I tested
   it on a 2 CPU DEC 4000 system and it worked there. But, I didn't
   have access to any other systems to verify those would work.

   I believe I can fix the problem, but I need volunteers that can
   run test versions of the cpu.c code on different MP systems. I'll
   need a 2100, DEC 7000 and DEC 4000 to verify the fix works.

   One person has tracked the failure into get_cpu_name() inside
   cpu.c where it tries to get the CPU type name. The quick fix
   here is to skip the check, turning:

        if( where ) {

   into:

        if( 0 ) {

   A failure here wouldn't explain why Monitor isn't collecting
   data for multiple CPUs though.

   My apologies for any inconvience this has caused. With some
   help I should be able to get the problems fixed quickly and
   get a new archive on gatekeeper.
