Conventions for relations between KLDCP and IOELEV
|
||||
|
||||
Core locations -
|
||||
|
||||
3000 KLDCP does JSR PC, here when it has nothing to do
|
||||
and 10 is running. IOELEV should INIT if it hasn't
|
||||
already, then go into its main loop. It should CLC, RTS PC
|
||||
if the 10 goes down; KLDCP will print appropriate message.
|
||||
To go into temporary KLDCP command mode, SEC, RTS PC.
|
||||
If microcode hangs, PMSG <...>, JMP 100004 (CTRLC).
|
||||
|
||||
3004, 3006 - .RAD50 /IOELEV/
|
||||
|
||||
3010, 3012 - random crufty version numbers (not actually used)
|
||||
|
||||
14, 16 BPT vector, I guess it's OK for 11 ddt to use these.
|
||||
|
||||
.. interrupt vectors for various devices are initially set
|
||||
up by KLDCP to point to error routine; IOELEV can load
|
||||
over these.
|
||||
|
||||
0-400 vectors
|
||||
3000-? IOELEV (what is 400-3000 used for?)
|
||||
?-100000 11 DDT
|
||||
100000-? KLDCP
|
||||
?-160000 stack
|
||||
|
||||
KLDCP will supply IOELEV with a stack; 11 DDT will have to be modified
|
||||
to believe it.
|
||||
|
||||
Even while the IOELEV main loop is not running, interrupts will be
|
||||
turned on and IOELEV P.I. level can run. Various things like "MR" will
|
||||
do a pdp11 "RESET" instruction and flush this. This allows the right thing
|
||||
to happen if the 10 halts, you go to KLDCP, in KLDCP you type DDT, and
|
||||
now you're back in IOELEV.
|
||||
|
||||
Consequently IOELEV has to handle the flavor of teletype that DDT & SALV use.
|
||||
|
||||
It's best to do an "RI" before running, e.g., DEC diagnostics.
|
||||
|
||||
IOELEV isn't allowed to turn on interrupts for any devices that KLDCP
|
||||
also uses; mainly, 60-cycle clock and DTE20. These have to be handled
|
||||
entirely in the main program and not touched at all at P.I. level (since
|
||||
IOELEV's P.I. level runs concurrently with KLDCP.)
|
||||
|
||||
IOELEV main program level can (and will) use KLDCP's EMT's to hack the DTE20.

KL10 CONSOLE INSTRUCTIONS
|
||||
|
||||
|
||||
Conventions:î____________
|
||||
|
||||
Commands end with carriage return. DELETE deletes the last character
|
||||
typed; deleted characters are echoed between backslashes. CTRL/U
|
||||
deletes the line being typed.
|
||||
|
||||
Numbers are octal. 36-bit numbers may be typed as two half-words
|
||||
separated by a space. Negative numbers may be entered; thus -1 means
|
||||
36 1-bits. In the following, <foo> is a symbol; don't type the angle
|
||||
brackets.
|
||||
|
||||
To examine and deposit memory:î______________________________
|
||||
|
||||
"EM <address>" types out the contents of the addressed location. If
|
||||
<address> is omitted, the last address used is used again. "EN"
|
||||
examines the last address used plus one. "EM <first> , <last>"
|
||||
examines the <first> address through the <last> address, inclusive.
|
||||
Don't put spaces around the comma.
|
||||
|
||||
"DM <address> : <contents>" deposits into memory. You can omit the
|
||||
<address>, but not the colon, to re-use the last address used.
|
||||
|
||||
Putting R and a space in front of a command repeats it, with
|
||||
typeout turned off, until you hit CTRL/C.
|
||||
|
||||
The Switches:î_____________
|
||||
|
||||
The left-most 16 switches are on the pdp11 panel. Numbers have been
|
||||
affixed to indicate the pdp10 bit numbers. The remaining switches are
|
||||
set by the "SW <octal value>" command. "SW" alone types out the
|
||||
current setting of the switches.
|
||||
|
||||
Running Diagnostics:î____________________
|
||||
|
||||
Load the DEC microcode with the "P U.RAM" command. Type "SM" to start
|
||||
the microcode. To run DG series diagnostics, which run in the pdp11,
|
||||
type e.g. "P DGKAB.A11", then "SED". To run other diagnostics, which
|
||||
run in the pdp10, type "P SUBRTN", then "P DDMMG" (for instance), then
|
||||
"STD" to start it.
|
||||
|
||||
Stopping a Running Program:î___________________________
|
||||
|
||||
Hit BREAK, then CTRL/C. If the running program is in the pdp10, the
|
||||
"SP" command is needed to stop it.
|
||||
|
||||
Powering the machine back on:î_____________________________
|
||||
|
||||
Check for boxes with no lights on; their circuit breakers may have
|
||||
tripped. Hit the DISK button to reload KLDCP. If it doesn't reload,
|
||||
disk unit 0 may need to be powered on and off. Type "RP0" to select
|
||||
disk unit 0. Do "J KLINIT". This loads the ITS microcode and
|
||||
configures memory and cache. If you get a bunch of "ADR=xxx COR=yyy
|
||||
ACT=000" messages, some memory is hung. Try resetting it. (RESET
|
||||
switch is at bottom right inside front door of each memory.)
|
||||
|
||||
Standard Tests:î_______________
|
||||
|
||||
"J KLDIAG" runs a series of diagnostics to check out the processor.
|
||||
Switch 0 is raised to stop each diagnostic (at the end of the current
|
||||
pass) and run the next. If it says "please load u code ver 73" do "P
|
||||
MBOX.RAM" then "HC". The "E bus diagnostic enable switch" is a toggle
|
||||
inside the front door of the left-most bay, near the "DTE SWITCH
|
||||
PANEL" decal.
|
||||
|
||||
To run memory tests, "P U.RAM", "SM", "PE0", "P SUBRTN", "P DDMMG",
|
||||
"STD". Or, "P DGKBB.A11", "SED".
|
||||
|
||||
Other Commands:î_______________
|
||||
|
||||
"MR" does a master reset of the machine.
|
||||
|
||||
"SM" starts the microcode. Try this if you get "? UCODE HUNG",
|
||||
"? EM ERR", etc.
|
||||
|
||||
"J NTSDDT" loads in an exec DDT from disk.
|
||||
|
||||
A complete list of KLDCP commands is in an 8 1/2 x 11 printout
|
||||
labelled "KLDCP OPR" around somewhere in the machine room.
