[comp.sys.mac] Sad Mac 0F000A - what does it mean?

  Hello everyone. It's Monday morning, and I fired up my Mac Plus this
morning and got a sad mac error 0F000A the first time I booted. Just the
sort of thing I expect to happen on a Monday morning.

  Ok, so I know that error 0F000A on booting a Mac is a line 1111
exception error. My question is just what is a line 1111 exception,
and what causes this error to happen? It's a bit of a worry.

  System : Mac 512ke upgraded to 2 meg/SCSI with MacRescue card, 20 meg
           drive running system 6.0.4. Rom revision - Lonely Heifer.
