These are console self-test flags.
This
is
the console program release version.
The boot block instructions are executed by the console microprocessor. They load the file
CONSOL.EXE
from the console tape cartridge in the TU58 drive unit into the
CPU
writeable
control store
(WCS). The console prompt
(»»
is
printed. The indirect command file POW-
ER.CMD
is
accessed on the cartridge. The commands within this file are performed.
a. Load the basic console microcode from the file
CONSLE.CPU
into the
CPU
WCS
starting
at
microaddress
O.
b.
Load the memory management, interrupts, and exceptions microcode from the file
MMIE.CPU
into the
CPU
WCS
starting
at
microaddress 0800 (hex).
c.
Load the initializing microcode from the file
POWER.CPU
into the
CPU
WCS starting
at
microaddress
OEOO
(hex).
d.
Start
the
CPU
microcode running at microaddress
OB
(hex). This microcode jumps to the
INIT
sequence
at
microaddress
OEOO
(hex). The
CPU
is
initialized, the first 64KB of
good main memory
is
found, and the presence
of
the internal disk controller (IDC) and the
floating-point accelerator
(FP
A)
is
noted.
e.
The console microprocessor waits for the
CPU
initialization sequence to be completed.
o The indirect command file CODEO I.CMD
is
accessed
on
the cartridge. The commands within
this file are now performed.
These commands load the microcode from the files
on
the cartridge into
CPU
WCS starting at
the addresses shown below:
