PDP-10 KA10 Basic Instruction Diagnostic #9
The PDP-10 KA10 Basic Instruction Diagnostic #9 (MAINDEC-10-DAKAI) test code has been extracted from DAKAIM.MAC [original] and DAKAIT.MAC [original] for use with the PDP-10 Test Machine with Debugger below.
This diagnostic "TESTS THE SHIFTING AND ROTATING INSTRUCTIONS."
Resources for this diagnostic include:
{% include machine.html id="testka10" %}
The Debugger's assemble ("a") command can be used to test the new built-in MACRO-10 Mini-Assembler, which supports a subset of the MACRO-10 assembly language. This command:
a DAKAI.MAC
will automatically read the DAKAI.MAC source file (a slightly modified copy of DAKAIM.MAC), assemble it, and then load the binary image at the location specified in the file.
Interesting MACRO-10 Bug
Take a look at this piece of original source code:
MOVSI AC+1,ZZ ;SET BIT (N) OF AC+1 LEFT
IFG <ZZ-2,>,<
MOVSI AC-1,YY ;SETUP FOR COMPARISON>
and the corresponding lines in the listing file:
11660 037024 205 07 0 00 000001 MOVSI AC+1,ZZ ;SET BIT (N) OF AC+1 LEFT
11661 IFG <ZZ-2,>,<
11662 037025 205 05 0 00 000000 MOVSI AC-1,YY ;SETUP FOR COMPARISON>
It's clear from the listing file that ZZ is 1, and therefore the IFG expression should be -1, so the MOVSI AC-1,YY should be suppressed. And my MACRO-10 Mini-Assembler does suppress it. But as you can see from DEC's listing file, they didn't suppress it. This results in an unfortunate mismatch between our respective instruction sequences from that point on.
Why did this happen? Since earlier identical IFG expansions work as expected, I have to assume that the spurious comma in that particular IFG pseudo-op somehow tripped up the expression evaluation. Commas are allowed in MACRO-10 expressions; for example:
777777,,666666
combines two 18-bit values (0o777777 and 0o666666) into a single 36-bit value (0o777777666666). But I'm not aware of a single comma meaning anything to MACRO-10, and it's pretty clear that the comma in that IFG is just a typo, so I'm not going to try to replicate MACRO-10's behavior here.
The PCjs expression evaluator (which is what my MACRO-10 Mini-Assembler uses) is OK with the comma, but not because it supports a comma operator (it doesn't); it simply allows numbers to contain commas, in case the user is using commas to group digits. So "2," is the same as "2".

1.0 ABSTRACT
THIS PDP-10 KA10 BASIC INSTRUCTION DIAGNOSTIC IS THE
NINTH IN A SERIES OF PDP-10 KA10 PROCESSOR DIAGNOSTICS.
THE DIAGNOSTIC TESTS THE SHIFTING AND ROTATING INSTRUCTIONS.
2.0 REQUIREMENTS
2.1 EQUIPMENT
A PDP-10 KA10 EQUIPPED WITH A MINIMUM OF 32K OF MEMORY
PAPER TAPE READER
CONSOLE TELETYPE
DECTAPE
LINE PRINTER (OPTIONAL)
2.2 STORAGE
THE PROGRAM RUNS WITHIN 32K OF MEMORY.
2.3 PRELIMINARY PROGRAMS
PREVIOUS PROCESSOR DIAGNOSTICS
3.0 PROGRAM PROCEDURES
3.1 LOADING PROCEDURE
THIS DIAGNOSTIC REQUIRES THAT THE DECSYSTEM10 SUBROUTINE
PROGRAM BE RESIDENT IN THE PDP-10.
PAPER TAPE - HARDWARE READ-IN (READER DEVICE CODE 104)
DECTAPE - LOAD WITH DIAMON (DECTAPE DEVICE CODE 320)
TIME SHARING - RUN UNDER DIAMON.
MAINDEC-10-DAKAI.TXT

3.2 STARTING PROCEDURE
A. SELECT OPERATIONAL CONSOLE DATA SWITCH SETTINGS (REFER TO
4.0 DATA SWITCH FUNCTIONS).
B. EXEC MODE
STAND-ALONE STARTING ADDRESS IS 30000.
C. USER MODE
RUN UNDER "DIAMON".
IN USER MODE THE FOLLOWING QUESTIONS WILL BE ASKED TO
SELECT THE OPERATIONAL SWITCHES:
TELETYPE SWITCH CONTROL ? 0,S,Y OR N (CR) -
IF THE OPERATOR TYPES "N", THE ACTUAL CONSOLE
SWITCHES ARE USED.
IF THE OPERATOR TYPES "Y", THE FOLLOWING QUESTIONS
ARE ASKED AND THE OPERATOR RESPONDS BY TYPING
THE ANSWER AS SIX OCTAL DIGITS REPRESENTING
THE DESIRED SWITCH SETTINGS.
SPECIFY LH SWITCHES IN OCTAL-
SPECIFY RH SWITCHES IN OCTAL-
IF THE OPERATOR TYPES "0", ZERO'S ARE USED FOR
THE SWITCH SETTINGS.
IF THE OPERATOR TYPES "S", PREVIOUSLY SET SWITCHES
ARE USED. THIS IS ONLY VALID UPON RESTARTING
OF AN INTERRUPTED PROGRAM.
MAINDEC-10-DAKAI.TXT

3.3 OPERATING PROCEDURE
A. TO THROUGHLY TEST ALL HARDWARE, ALL TEST CONTROL DATA
SWITCHES SHOULD BE SET TO 0.
B. WHEN DEBUGGING HARDWARE, SET SWITCHES TO 0. ALLOW THE
TELETYPE TO PRINT THE ERROR MESSAGES. THIS ALLOWS THE
PROGRAM TO RUN A COMPLETE PASS AND THEN THE ERROR MESSAGES
MAY BE CORRELATED TO QUICKLY DIAGNOSE THE FAILURE. IF A
HARDWARE PROBLEM IS SUCH THAT THE ERROR MESSAGES, AFTER THE
FIRST ONE, HAVE NO MEANING (FIRST ERROR CAUSES ALL FOLLOWING
TESTS TO FAIL) SET THE LOOP ON ERROR SWITCH AND RESTART THE
TEST FROM THE BEGINNING. THE FIRST FAILURE WILL THEN CAUSE
THE PROGRAM TO ENTER A LOOP SUITABLE FOR SCOPING.
THE ERROR MESSAGE USED IN CONJUNCTION WITH THE LISTING AND
SCOPING IF NECESSARY SHOULD ALLOW THE FAILING CONPONENT
TO BE ISOLATED AND REPLACED AND/OR REPAIRED.
C. WHEN TAKING MARGINS, SET DATA SWITCHES 'NOPNT' AND 'DING'.
THIS WILL INHIBIT PRINTOUT BUT WILL ALLOW THE TELETYPE
BELL TO BE RUNG WHEN A ERROR OCCURS. IF THE MARGIN OBTAINED
IS UNACCEPTABLE, THE OPERATOR MAY REVERT TO STANDARD SWITCH
SETTINGS FOR DEBUGGING PURPOSES.
D. ERROR INFORMATION MAY BE OBTAINED QUICKLY BY PRINTING
ERRORS ON THE LINE PRINTER.
E. IN THE EVENT OF A PRINT ROUTINE FAILURE THE 'NOPNT' SWITCH
AND THE 'ERSTOP' SWITCH MAY BE SET TO INHIBIT PRINTOUT
BUT HALT THE PROGRAM POINTING TO THE ERROR.

5.0 ERRORS
ERRORS ARE PRINTED ON THE TTY OR LINE PRINTER. THE ERROR
PRINTOUT CONTAINS THE TEST TITLE, THE PC OF THE FAILURE, ERROR
NUMBER AND THE CONTENTS OF AN APPLICABLE AC.
THE PC VALUE IS USEFUL IN RELATING THE FAILURE TO THE LISTING.
THE ERROR NUMBER IS PROVIDED SUCH THAT AN ERROR DICTIONARY MAY
BE MADE AT SOME FUTURE DATE.
WHEN THE SCOPE LOOP MODE IS USED THE MI REGISTER WILL COUNT
FOR EACH OCCURANCE OF AN ERROR. IF AN AUDIO INDICATION OF
A CONTINUING ERROR IS DESIRED THE 'DING' SWITCH MAY BE SET.
6.0 ITERATION COUNTER
THE ITERATION COUNT OF THE PROGRAM IS DISPLAYED IN THE MEMORY
INDICATORS (MI). THIS COUNT IS A DECREMENTING COUNT AND
INITIALLY STARTS AT -1 IN STAND-ALONE OPERATION.
7.0 CYCLE TIME
THE CYCLE TIME OF THE PROGRAM IS IN THE MILLISECOND RANGE AND
IS THEREFORE SUITABLE FOR TAKING MARGINS, VIBRATION TESTS,
ETC.

8.0 OPERATIONAL VARIATIONS
A. DIAGNOSTIC MONITOR
THE PROGRAM IS USABLE WITH THE DIAGNOSTIC MONITOR TO PROVIDE
RELIABILITY TESTS, ACCEPTANCE TESTS, AND/OR TO PROVIDE A
QUICK METHOD OF ISOLATION OF A FAULT TO A PARTICULAR AREA
OF THE PROCESSOR. CERTAIN PROCEDURES ARE USED WHEN THE
PROGRAM IS USED IN THIS MANNER. THEY ARE:
1. THE DIAGNOSTIC MONITOR TRANSFERS CONTROL TO THE PROGRAM
AND STARTS IT AT LOCATION 30002.
2. MONCTL - LOCATION 30043 IS USED AS THE DIAGNOSTIC MONITOR
CONTROL WORD.
LH = 0, STAND-ALONE OPERATION
-1, RUNNING UNDER DIAGNOSTIC MONITOR
RH = RIGHT HALF OF CONSOLE SWITCHES IF UNDER
DIAGNOSTIC MONITOR CONTROL.
B. USER MODE
TO OUTPUT THE PRINTED ERROR MESSAGES TO A USER SPECIFIED
DEVICE IN USER MODE, ASSIGN THE DESIRED OUTPUT DEVICE TO
DEVICE NAME 'DEV' AND SET SWITCH 'PNTLPT'. THE PHYSICAL
DEVICE USED CAN BE ANY DEVICE THAT CAN ACCEPT ASCII OUTPUT
FORMAT SUCH AS LPT, DSK, DTA, ETC. THE CORRESPONDING
OUTPUT FILE IS 'DAKAI.TMP'
EXAMPLE DEVICE ASSIGNMENT:
.ASSIGN DSK DEV
IN USER MODE THE PROGRAM WILL MAKE 1000(8) PASSES AND THEN
RETURN TO DIAMON COMMAND MODE.
MAINDEC-10-DAKAI.TXT
PAGE 9
8.0 OPERATIONAL VARIATIONS (CON'T)
THE OUTPUT FILE (IF USED) MAY THEN BE LISTED BY USING THE
NORMAL MONITOR COMMANDS (PRINT, LIST, TYPE, PIP, ETC.).
IF THE PROGRAM IS ABORTED BEFORE COMPLETION (BY ^C, ETC.) THE
OUTPUT FILE MAY BE CLOSED BY USING THE MONITOR 'REENTER'
COMMAND.
C. SYSTEM EXERCISER
START ADDRESS IS 30003. DATA SWITCHES ARE PRESTORED IN
'SWTEXR' LOC 30023.
9.0 MISCELLANEOUS
THE NON-EX-MEMORY AND PARITY STOP SWITCHES SHOULD BE RESET
(0). THESE ERRORS, ILLEGAL UUO'S AND OTHER ERRORS OF THIS
TYPE ARE HANDLED BY PRINTOUT ON THE TELETYPE.
