Changed the RESET button to *not* autoStart a machine when a Debugger is present, so that the Debugger can "cleanly" load bootstrap sequences and boot without side-effects (eg, unexpected interrupts)

Loading the RX11 Bootstrap
--------------------------
From the [RT-11 v4.0 Installation Manual (March 1981)](/pubs/dec/pdp11/rt11/), p. E-9:
The procedure to deposit the RX11 disk bootstrap loader in memory depends on the type of processor you have.
If your computer is a PDP-11V/03, PDP-11/03, or LSI-11, see the PDP-11/03 user's manual for instructions.
1. Set the ENABLE/HALT switch to HALT.
2. Set the first address, 010000, in the switch register (see Table E-3).
3. Press the LOAD ADDR switch.
4. Set the contents for the first address (from Table E-3) in the switch register.
5. Lift the DEP switch. The computer automatically advances to the next address.
6. Set the contents for the next address (from Table E-3) in the switch register.
7. Lift the DEP switch.
8. Repeat steps 6 and 7 until you have deposited all the instructions.
Now verify that you deposited the bootstrap program properly.
1. Set the first address, 001000, in the switch register.
2. Press the LOAD ADDR switch.
3. Press the EXAM switch to display the contents of that address in the data register.
4. Compare the number in the data register with the value for that address in Table E-3.
5. If the values are the same, press EXAM again to display the contents of the next address.
If the values are not the same, repeat the entire procedure for depositing the bootstrap.
Verify the contents of all the addresses in this way. If any instruction is incorrect,
repeat the entire deposit procedure.
Once you have correctly deposited the bootstrap in memory, start the computer as follows:
1. Set the starting address, 001000, in the switch register.
2. Press the LOAD ADDR switch.
3. Set the ENABLE/HALT switch to ENABLE.
4. Press the START switch.

Loading the RX-11 Bootstrap Loader
----------------------------------
Any PDP-11 machine using built-in PCjs Debugger makes it easy to enter the bootstrap code above. Paste
the following commands into the Debugger's command buffer:
ew 1000 005000 012701 177170 105711 001776 012711 000003 005711 001776;
ew 1022 100405 105711 100004 116120 000002 000770 000000 005000 000110;
r pc 1000
You can then review (eg, disassemble) the bootstrap code:
>> u 1000 1044
001000: 005000 CLR R0
001002: 012701 177170 MOV #177170,R1

001010: 001776 BEQ 001006

001016: 005711 TST @R1
001020: 001776 BEQ 001016
001022: 100405 BMI 001036
001024: 105711 TSTB @R1
001026: 100004 BPL 001040
001030: 116120 000002 MOVB 2(R1),(R0)+
001034: 000770 BR 001016
001036: 000000 HALT
001040: 005000 CLR R0
001042: 000110 JMP @R0
Last but not least, make sure you have successfully loaded an RX01 diskette image into drive DX0. Then execute the
bootstrap code with the Debugger's "g" command.
Of course, if the machine also includes the RX11 Boot control, then all you *really* need to is select an
RX01 diskette, click "Load", wait for the diskette image to be successfully loaded (i.e., downloaded) and then click
"Boot".
