|
;* Supermon 816 is a salute to Jim Butterfield, who passed away on June 29, 2007. *
|

|
;* *
|
| 22 |
|
|
;* Jim, who was the unofficial spokesman for Commodore International during the *
|
| 23 |
|
|
;* heyday of the company's 8 bit supremacy, scratch-developed the Supermon machine *
|
| 24 |
|
|
;* language monitor for the PET & CBM computers. When the best-selling Commodore *
|
| 25 |
|
|
;* 64 was introduced, Jim adapted his software to the new machine & gave the adap- *
|
| 26 |
|
|
;* tation the name Supermon 64. Commodore subsequently integrated a customized *
|
| 27 |
|
|
;* version of Supermon 64 into the C-128 to act as the resident M/L monitor. *
|
| 28 |
|
|
;* *
|
| 29 |
|
|
;* Although Supermon 816 is not an adaptation of Supermon 64, it was decided to *
|
| 30 |
|
|
;* keep the Supermon name alive, since Supermon 816's general operation & user in- *
|
| 31 |
|
|
;* terface is similar to that of Supermon 64. Supermon 816 is 100 percent native *
|
| 32 |
|
|
;* mode 65C816 code & was developed from a blank canvas. *

|
;* Supermon 816 is a full featured monitor and supports the following operations: *
|
| 38 |
|
|
;* *
|
| 39 |
|
|
;* A — Assemble code *
|
| 40 |
|
|
;* C — Compare memory regions *
|
| 41 |
|
|
;* D — Disassemble code *
|
| 42 |
|
|
;* F — Fill memory region (cannot span banks) *
|
| 43 |
|
|
;* G — Execute code (stops at BRK) *
|
| 44 |
|
|
;* H — Search (hunt) memory region *
|
| 45 |
|
|
;* J — Execute code as a subroutine (stops at BRK or RTS) *
|
| 46 |
|
|
;* M — Dump & display memory range *
|
| 47 |
|
|
;* R — Dump & display 65C816 registers *
|
| 48 |
|
|
;* T — Copy (transfer) memory region *
|
| 49 |
|
|
;* X — Exit Supermon 816 & return to operating environment *
|
| 50 |
|
|
;* > — Modify up to 32 bytes of memory *
|
| 51 |
|
|
;* ; — Modify 65C816 registers *
|
| 52 |
|
|
;* *
|
| 53 |
|
|
;* Supermon 816 accepts binary (%), octal (@), decimal (+) and hexadecimal ($) as *
|
| 54 |
|
|
;* input for numeric parameters. Additionally, the H and > operations accept an *
|
| 55 |
|
|
;* ASCII string in place of numeric values by preceding the string with ', e.g.: *
|
| 56 |
|
|
;* *
|
| 57 |
|
|
;* h 042000 042FFF 'BCS Technology Limited *
|
| 58 |
|
|
;* *
|
| 59 |
|
|
;* If no radix symbol is entered hex is assumed. *
|
| 60 |
|
|
;* *
|
| 61 |
|
|
;* Numeric conversion is also available. For example, typing: *
|
| 62 |
|
|
;* *
|
| 63 |
|
|
;* +1234567 *
|
| 64 |
|
|
;* *
|
| 65 |
|
|
;* will display: *
|
| 66 |
|
|
;* *
|
| 67 |
|
|
;* $12D687 *
|
| 68 |
|
|
;* +1234567 *

|
;* @04553207 *

|
| 71 |
|
|
;* *
|
| 72 |
|
|
;* In the above example, means the console keyboard's return or enter key. *
|
| 73 |
|
|
;* *
|
| 74 |
|
|
;* All numeric values are internally processed as 32 bit unsigned integers. Addr- *
|
| 75 |
|
|
;* esses may be entered as 8, 16 or 24 bit values. During instruction assembly, *
|
| 76 |
|
|
;* immediate mode operands may be forced to 16 bits by preceding the operand with *
|
| 77 |
|
|
;* an exclamation point if the instruction can accept a 16 bit operand, e.g.: *
|
| 78 |
|
|
;* *
|
| 79 |
|
|
;* a 1f2000 lda !#4 *
|
| 80 |
|
|
;* *
|
| 81 |
|
|
;* The above will assemble as: *
|
| 82 |
|
|
;* *
|
| 83 |
|
|
;* A 1F2000 A9 04 00 LDA #$0004 *
|
| 84 |
|
|
;* *
|
| 85 |
|
|
;* Entering: *
|
| 86 |
|
|
;* *
|
| 87 |
|
|
;* a 1f2000 ldx !#+157 *
|
| 88 |
|
|
;* *
|
| 89 |
|
|
;* will assemble as: *

| 90 |
|

|
;* A 1F2000 A2 9D 00 LDX #$009D *
|
| 92 |
|
|
;* *
|
| 93 |
|
|
;* Absent the ! in the operand field, the above would have been assembled as: *
|
| 94 |
|
|
;* *
|
| 95 |
|
|
;* A 1F2000 A2 9D LDX #$9D *
|

;* A Note on the PEA & PEI Instructions *
|
| 101 |
|
|
;* ———————————————————————————————————— *
|
| 102 |
|
|
;* *
|
| 103 |
|
|
;* The Eyes and Lichty programming manual uses the following syntax for the PEA *
|
| 104 |
|
|
;* and PEI instructions: *
|
| 105 |
|
|
;* *
|
| 106 |
|
|
;* PEA *
|
| 107 |
|
|
;* PEI () *
|
| 108 |
|
|
;* *
|
| 109 |
|
|
;* The WDC data sheet that was published at the time of the 65C816's release in *
|
| 110 |
|
|
;* 1984 does not indicate a recommended or preferred syntax for any of the above *
|
| 111 |
|
|
;* instructions. PEA pushes its operand to the stack and hence operates like any *
|
| 112 |
|
|
;* other immediate mode instruction, in that the operand is the data (however, PEA *
|
| 113 |
|
|
;* doesn't affect the status register). Similarly, PEI pushes the 16 bit value *
|
| 114 |
|
|
;* stored at and +1, and hence operates like any other direct *
|
| 115 |
|
|
;* (zero) page instruction, again without affecting the status register. *
|
| 116 |
|
|
;* *
|
| 117 |
|
|
;* BCS Technology Limited is of the opinion that the developer of the ORCA/M as- *
|
| 118 |
|
|
;* sembler, which is the assembler referred to in the Eyes and Lichty manual, mis- *
|
| 119 |
|
|
;* understood how PEA and PEI behave during runtime, and hence chose an incorrect *
|
| 120 |
|
|
;* syntax for these two instructions. This error was subsequently carried forward *
|
| 121 |
|
|
;* by Eyes and Lichty. *
|
| 122 |
|
|
;* *
|
| 123 |
|
|
;* Supermon 816's assembler uses the following syntax for PEA and PEI: *
|
| 124 |
|
|
;* *
|
| 125 |
|
|
;* PEA # *
|
| 126 |
|
|
;* PEI *
|
| 127 |
|
|
;* *
|
| 128 |
|
|
;* The operand for PEA is treated as a 16 bit value, even if entered as an 8 bit *
|
| 129 |
|
|
;* value. The operand for PEI must be 8 bits. *

putcha =$F406 ;print character on console...
|
| 285 |
|
|
;
|
| 286 |
|
|
; PUTCHA refers to an operating system API call that prints a character to
|
| 287 |
|
|
; the console screen. The character to be printed will be in .A, which
|
| 288 |
|
|
; will be set to 8-bit width. Supermon 816 assumes that PUTCHA will block
|
| 289 |
|
|
; until the character can be processed. PUTCHA will be called with a JSR
|
| 290 |
|
|
; instructions.
|
| 291 |
|
|
;
|
| 292 |
|
|
; Supermon 816 expects .X & .Y to be preserved upon return from PUTCHA.
|
| 293 |
|
|
; You may have to modify Supermon 816 at all calls to PUTCHA if your "put
|
| 294 |
|
|
; character" routine works differently than described.

stopkey =$03 ;display abort key...
|
| 299 |
|
|
;
|
| 300 |
|
|
; Supermon 816 will poll for a "stop key" during display operations, such
|
| 301 |
|
|
; as code disassembly & memory dumps, so as to abort further processing &
|
| 302 |
|
|
; return to the command prompt. STOPKEY must be defined with the ASCII
|
| 303 |
|
|
; value that the "stop key" will emit when typed. The polling is via a
|
| 304 |
|
|
; call to GETCHA (described above). The default STOPKEY definition of $03
|
| 305 |
|
|
; is for ASCII or [Ctrl-C].

;
|
| 311 |
|
|
; ————————————————————————————————————————————————————————————————————————
|
| 312 |
|
|
; Supermon 816 will use the above definitions for input buffers. These
|
| 313 |
|
|
; buffers may be located anywhere in RAM that is convenient. The buffers
|
| 314 |
|
|
; are stateless, which means that unless Supermon 816 has control of your
|
| 315 |
|
|
; system, they may be overwritten without consequence.

|
|
; The following macros execute terminal control procedures that perform
|
| 631 |
|
|
; such tasks as clearing the screen, switching between normal & reverse
|
| 632 |
|
|
; video, etc. These macros are for WYSE 60 & compatible displays, such as
|
| 633 |
|
|
; the WYSE 150, WYSE 160, WYSE 325 & WYSE GPT. Only the functions needed
|
| 634 |
|
|
; by Supermon 816 are included.
|
| 635 |
|
|
;
|
| 636 |
|
|
; If your console is not WYSE 60 compatible, you will need to edit these
|
| 637 |
|
|
; macros as required to control your particular console or terminal. Note
|
| 638 |
|
|
; that in some cases one macro may call another. Exercise caution in your
|
| 639 |
|
|
; edits to avoid introducing display bugs.
|
| 640 |
|
|
;
|
| 641 |
|
|
; If your console display cannot execute one of these procedures, such as
|
| 642 |
|
|
; 'CL' (clear to end of line), you will have to develop an alternative.
