Cartridge^ £DiskMate
DISKMATE.
INSTRUCTIONS. Never connect or disconnect a cartridge while the power
is on.
The Diskraate cartridge features a reset button and a small switch on
the rear of the unit. The switch effectively makes Diskmate two
cartridges in one so these instructions will treat it as such.
Switch Down. In this position you will be presented with a menu on
power up as follows;
F. Fast Format. This option will format a disk in about 10 seconds.
Simply select ’F’ and then enter disk name and ID when prompted.
Note. Formatting a disk will des-coy any previous data on it.
I. Install fastload. This feature will ioad programs at about 5 times
normal speed. When you press * I’ a dot will appear alongside to
indicate that the module installed. If you now ’Q’uit to basic you
can use the feature.
NB Fast load will not speed up seme software particularly programs
that already feature their own f^st loader.
U. Utility commands. Select ’U’ and a dot will appear to indicate
that the module is installed. If you now ’Q'uit to basic you can
use the following keywords;
$ _ _ _D i rectory .
®$ __ _Directory - .
_DIR __ _ _ Dir ect ory._
. @S0: filename _ _ _ So ra*~ h fi le.
gjxu: newname-oidnaiiio "Rename a file
@10 Ini tia liz e d isk driv e.
@V0 _ Validate a diskette.
@ __ Read_error channel
/fi1ename Load haslc program
, _ __ status key. ...
C. 4 minute copier. Copy a complete disk even some protected
software. Simply follow the on screen prompts.
Q. Quit will take you back to basic. Can be re entered with reset
or SYS 32802.
Switch up. In this position on power up or reset you will enter into
the Micromon monitor. The usual proceedure might be to load the
program to be veiwed and then reset to enter Micromon.The first screen
will display the present register status and prompt for a command.
A complete list of Micromon commands are attached.
Notes;
1, All capital letters must be typed as shown. Lowercase letters stand
for information to be supplied by the user, ie (hh= any Hex value)
2, All numbers must be entered in Hex (with no $ ). Except in number
conversion functions.
3, The brackets \£ around an item mean that it is optional. ( Don’t
type the brackets.)
Output Commands
P (PRINT) Switches all output from the screen to the printer
(device 4) or vice versa. You must hit return TWICE after the P
before entering next command. Use P again to return output to
bSffPr’(Hp^ e J aSt -U" e ? f P r i ntin 9 is 'stuck' in the printer
buffer (delayed printing), switching output to printer and back
again should cause it to print.
OPEN filenum, dev [,s.a.] [."string"] :CMD filenum - (General
output; If the "P" command fails to work correctly with your
printer, exit to BASIC and enter this line. Use the correct
device number and s.a. (secondary address, if needed) for your
printer. If a string is specified, it will be used as a title
Reenter MICROMON and perform the desired functions. When you're
llSlilS?, Wlth the printer, exit to BASIC arid enter
PRINT#fi1enum rCLOSE filenum. This technique can also be used to
o*^ re Th« tp + t - 1n a -il S c fl1e » by giving the appropriate device,
etc. The string will be used as a file name. Be sure to open the
file for writing by putting ",W" in file name after the file type
(r , b or U) . r
Debugging Commands
G [addr] - (GO) Restores the values of the registers, etc.
that were saved when MICROMON was entered (see R command) and
^ < . e + u exe i U ^ eS - an ^ r 0 u t i n e • ^ [addr] is given, execution begins
at that location. Otherwise, execution begins at the location
given by the saved program counter. The ML routine must end with
a BRK instruction in order to return to MICROMON.
V [addr] - (WAiv) Restores th n saved values nf the _reois±ers
etc. and begins executing ML code one instruction at a time!
Prior to executing an instruction (except the first), the
following values are displayed: the status. A, X, and Y
registers; the stack pointer; the program counter (address of
next instruction); and finally, the hex and mnemonic for the next
instruction. If [addr] is specified, execution begins at that
location. Otherwise the saved value of the program counter is
used. Pressing anykey (except J and STOP) will execute the next
instruction. Pressing the "J" key will execute a subroutine
uninterrupted, until an RTS instruction is encountered. Executing
S T ;2LnI! StrUCtion or hittin 9 the STOP key will return to normal
MICROMON command mode and save the current register, etc. values.
Q [addr] - (QUICK TRACE) Exactly like the "W" command except:
execution is continuous; the instructions executed are not
displ a yed; use STOP and "=" keys simultaneously to return to
MICROMON; the "B" command can be used to set an optional
"breakpoint".
8 ad 2 r 1( £ hhhh J ‘ (BREAKPOINT SET) Sets up a "breakpoint" for
the "Q" command. When execution reaches the address given, a BRK
instruction is executed to return to MICROMON. If [hhhh] is
specified, the BRK is executed only after the given address has
been executed that number of times.
Exit Commands
X - (SOFT EXIT) Exits MICROMON to BASIC, leaving the BRK and
IRQ vectors as set by MICROMON. This allows you to 'hot-start'
MICROMON by executing a BRK instruction from BASIC, using SYS 8
for instance. The "X" command will leave PROMOS enabled.
E - (HARD EXIT) Exits MICROMON to BASIC but restores the
previous contents of the BRK and IRQ vectors (set by PROMOS).
MICROMON must be cold-started to reenter it. This command will
leave PROMOS enabled.
K - (KILL) Exits MICROMON to BASIC and restores the power-up
values of the BRK and IRQ vectors. Same effect as
RUN/STOP-RESTORE.
G FCE2 - (RESET) Totally resets the computer.
File commands
L [alt. addr] "file" [,dev] - (LOAD) Loads a file from disk
(no tape). If [,dev] is omitted, device 8 will be selected. If
[alt. addr.] is specified, the file will be loaded at that
address rather than its normal load address. This is very useful
for EPROM work. After loading, the ending address of the program
( + 1) will be printed .
shift-L [alt. addr] "file" [,dev] - (Dummy LOAD) Same as L,
but does not actually load the file. Used to find the ending
address of a program (+1).
V "file" [,dev] - (VIEW) Prints the load address of the file,
but does not load it.
S "file", start, end+1 [,dev] - (SAVE) Saves an area of memory
to disk. Note that the end address you give must be 1 greater
than the actual end.
Memory Commands
A addr instruction - (ASSEMBLE) Assembles one ML instruction
into memory starting at the specified address. All addresses in
the INSTRUCTION must be preceded by a $. Also automatically
inserts an "A" on the following line to prepare for assembling
another statement. Hit return or move to a blank line to end
assembly.
N code-start code-end offset ref-begin ref-end [W]
(NEW LOCATION) Used to relocate a section of ML code - sort of
like a RENUMBER command in BASIC. After moving the code with the
"T" command, this command will adjust absolute memory references
(not branch locations) to reflect the code's new location. The
area specified by code-start and code-end will be searched for
any (three-byte) instructions which reference the area specified
by ref-start and ref-end. Any references found will be adjusted
by adding the offset value. To calculate the proper offset,
subtract the original start address from the new start address,
using the command. The [W] option specifies that a table of
two-byte vectors (Words) is being searched rather than ML code.
See the chapter on reusing the tape routines in the KERNAL for an
example of using this command.
0 instr-addr target-addr - (OFFSET) Used to calculate the
offset for branch instructions. Instr-addr is the address of the
branch instruction itself and target-addr where you want it to
branch to. This command is pretty useless since MICROMON
automatically calculates the offset for you when you assemble a
branch instruction. Don't use this command for calculating
offsets for the "N" command.
$ hhhh - (HEX CONVERSION) Converts the hex number hhhh into
decimal, ASCII characters and binary.
# ddddd - (DECIMAL CONVERSION) Converts the decimal number
ddddd into hex, ASCII characters and binary.
% bbbbbbbb - (BINARY CONVERSION) Converts the binary number
bbbbbbbb into hex, decimal, and ASCII characters.
"a " (ASCII CONVERSION) Converts the ASCII character a into
hex, decimal and binary.
+ hhhh hhhh -
(HEX
ADDITION) Adds
the
two
hex
numbers
and
gives a one-byte
the low byte is

result. If the
result

SUBTRACTION)
•
Subtracts

hex
& start end - (CHECKSUM) Checksums an area of memory by ADDing
together all of the bytes. The result is limited to two hex
bytes.
