automatically execute in response to pressing RESET and
START during system turn-on. They can also be initiated
from the CPU Monitor by pressing RESET and entering T <CAR-
RIAGE RETURN).
SPUD tests the prima~y functions of the CPU and peripheral
components. The diagnostics verify the system's ability to
execute a limited number of instructions, and to communicate
with Winchester Disk and Tape Cartridge Controllers. The
specific functions of SPUD are:
(1) System 8000 Instruction Test
