tasm: Number of errors = 0

AIM 65 MICROCOMPUTER MONITOR PROGRAM LISTING
Rockwell International

Document No. 29650 N36L
Rev. 1, April 1979

I used the Telemark Cross Assembler v3.1 (TASM) to re-create the source code.

See http://www.halcyon.com/squakvly/

I tried to exactly duplicate the original source but some errors may exist.
The exceptions are when the original had a hexadecimal constant instead

of an ASCII constant or ASCII equate (especially CR) in some immediate
mode instructions; I changed them to ASCII constants or an equate.

For example, line 468 in the printed listing is:

0468  E185  A9 BC       STA1   LDA #$BC        ;"<" CHR WITH MSB=1 FOR DISP

My version is:
0468   E185 A9 BC       STA1   LDA #'<'+$80    ;"<" CHR WITH MSB=1 FOR DISP

The TASM assembler is not the same one that Rockwell used to write the

code, so some assembler directives and opcode formats are different.
However, the ASM file uses the same line numbering as the printed listing.

That is, line 1000 in the printed listing corresponds to line 1000 in the
ASM file and line 1000 in the LST file.

I could not fully read eight lines in the program listing because I was

looking at a scanned copy, not the original.  The rightmost characters
were lost in the binding.  These are the lines:

0149  HIST   =NAME           ;FOUR LAST ADDR + NEXT (SINGL STEP)

1796         JSR SWSTAK      ;SWAP X , Y WITH RTRN ADDR FROM S
1804         JSR SWSTAK      ;SWAP X , Y WITH RTRN ADDR FROM

2159  RDBIT  LDA TSPEED      ;ARE WE IN C7 OR 5B,5A FREQUENC
2262  OUTDP1 JMP (DILINK)    ;HERE HE COULD ECHO SOMEWHERE ELSE

3205         BNE IN02        ;CONTIN , DISP WONT ALLOW > 60 CHR
3719         LDA TYPE        ;CHCK FOR BRNCH WITH RELATIVE ADDR

3727  TRY34  LDA #04         ;CHECK FOR ABSOLUTE OR ZP,X ORZP,

NOTE: I have since been told that the cut-off lines above exist in the
original manual.
