APPENDIX B \- LOADING THE TAPE MONITOR
.sp 2
.R
.NL
.PP
This section describes how the bootstrap monitor located on
the first tape of the distribution tape set may be loaded.
This should not be necessary, but has been included as a fallback
measure if it is not possible to read the distributed
console medium.  \fBWARNING\fP:  the bootstraps supplied below
may not work, in certain instances on an 11/730 because they
use a buffered data path for transferring data from tape to
memory; consult our group if you are unable to load the 
monitor on an 11/730.  All of the addresses given below refer
to the first SBIA on the 8650 and 8600.
.PP
To load the tape bootstrap monitor, first
mount the magnetic tape on drive 0 at load point, making
sure that the write ring is not inserted.
Temporarily
set the reboot switch on an 11/785, 11/780, or 11/730 to off;
on an 8650, 8600, or 11/750 set the power-on action to halt.
(In normal operation an 11/785, 11/780, or 11/730
will have the reboot switch on,
and an 8650, 8600, or 11/750 will have the power-on action
set to boot/restart.)
.PP
If you have an 8650, 8600, 11/785 or 11/780 give the commands:
.RT
.DS
\fB>>>\|\fPHALT
\fB>>>\|\fPUNJAM
.DE
Then, on any machine, give the init command:
.DS
\fB>>>\|\fPI
.DE
and then
key in at location 200 and execute either the TS, HT, TM, or MT
bootstrap that follows, as appropriate.  \fBNOTE\fP: All of the addresses
given in this section refer to the first SBIA on the 8650 and 8600.
The machine's printouts are shown in boldface,
explanatory comments are within ( ).
(You can use `delete' to erase a character and `control U' to kill the
whole line.)

If the tape doesn't move the first time you start the bootstrap
program with ``S 200'' you probably have entered the program
incorrectly (but also check that the tape is online).
Start over and check your typing.
For the HT, MT, and TM bootstraps you will not be able to see the
tape motion as you advance through the first few blocks
as the tape motion is all within the vacuum columns.

Next, deposit in R10 the address of the tape MBA/UBA and in R11 the

You are now talking to the tape bootstrap monitor.
At any point in the following procedure you can return
to this section, reload the tape bootstrap, and restart the
procedure.  The console monitor is identical to that
loaded from a TU58 console cassette, follow the instructions
in section 2 as they apply to this device.  The only
exception is that when using programs loaded from the
tape bootstrap monitor, programs will always return to
the monitor (the ``='' prompt).  This saves your having
to type in the above toggle-in code for each program to
be loaded.
