- *** Ram Tools ***
-
- The ultimate utilities program that stays in RAM!!!!
-
-
-
- So what is this program all about???
-
- Ram Tools is a RAM resident utility program that sits ABOVE
- CP/M SO IT DOES NOT ANY TPA SPACE. When this program is
- installed, with the touch of a key, you get the following
- commands: Screen Saver(This is the Screen Saver program
- available to you in RAM, anytime[Screen Saver will be
- discussed later in this document]), Turning the cursor into
- a solid block, clear the screen, cold boot(It asks you if
- you want to reset the computer before it does it), and send
- chars to the printer. ALL THIS WITHOUT TAKING ANY TPA
- SPACE!!!
-
- System Requirements:
-
- Kaypro 4'84 running plain CP/M, or ZCPR3. This will also
- work on the EPEX operating environment. THE ABOVE ARE THE
- ONLY COMPUTERS/OPERATING SYSTEMS THAT I HAVE TESTED THIS
- PRODUCT ON. IT MAY WORK WITH OTHERS TOO. This may work
- with other 84 kaypros, so long as the BIOS entry point is
- F400. HOWEVER, AS FAR AS I KNOW THIS PROGRAM WILL ONLY
- WORK ON THE KAYPROS THAT HAVE GRAPHICS CAPABILITIES. The
- code is included, so you can make your own changes. IF
- Ram Tools is found not to work on your computer/CP/M
- operating system replacement, write me a letter with the
- address of the bios, the type(name) of the computer, along
- with the following screen commands: Clear screen, status
- line on/off(a permanent 25th line), remember last cursor
- position, return to remembered cursor position, clear to
- end of line, turn cursor on/off, and I'll see what I can
- do. (THE ABOVE VIDEO COMMANDS MUST BE AVAILABLE UNLESS YOU
- DON'T CARE ABOUT GARBAGE ON YOUR DISPLAY SCREEN)[owners of
- '84 Kaypros do not need to include the video commands]
-
- Invoking RamTools:
-
- getting RamTools(RT) installed in memory is quite easy.
- All you have to do is rename the proper installation of
- RamTools to RT, Then just type RT. So far, there are only
- 2 versions of RT in this library: RTCPM, and RTZCPR. If
- you are using plain CP/M, use RTCPM. If you are using
- ZCPR3, use RTZCPR.
-
- Once you have RT renamed, all you have to do is type "RT"
- at the A0> prompt. It will tell you that it is ready, and
- put a little command summary at the bottom of the screen(IF
- THE COMMAND SUMMARY GOES AWAY, IT DOES NOT MEAN THAT RT HAS
- GONE AWAY TOO... IT JUST MEANS THAT SOME PROGRAM NEEDED
- THE STATUS LINE FOR SOMETHING).
-
- Note: when you run RT, the cursor will also turn into a
- block automatically, because I hate blinking cursors, and
- if I have this program do it, I don't need to put another
- program on the disk to turn the cursor into a block.
-
- You may wish to put RT in your startup batch file/program,
- or make it an autoboot program(I'll tell you how to do that
- later...)
-
- Removing RT from memory:
-
- You may remove RT from memory either 2 ways: do a cold
- boot(press the reset button) of the computer(this may also
- be done by pressing the key which activates the cold boot
- feature in this program). OR, you can just run the RT
- program again... it toggles itself in and out of memory
- (running RT the first time would put it in memory, running
- rt the second time would take it out of memory, running it
- a third time would put it back in memory, etc)
-
- OK... ALL THIS IS GREAT, BUT HOW DO I USE THE PROGRAM???
-
- NOTE: AFTER ACTIVATION OF ONE OF THESE KEYS, AN ADDITION-
- AL KEY MAY HAVE TO BE PRESSED IN ORDER FOR THE PROGRAM YOU
- ARE CURRENTLY RUNNING TO GAIN CONTROL AGAIN. ALSO, DURING
- THE OPPERATION OF THESE UTILITIES, THE PROGRAM EXECUTION OF
- THE PROGRAM CURRENTLY IN MEMORY WILL BE SUSPENDED.
- However, when using the internal modem, the modem will
- still emit the "carrier", so you can use the utilities
- while on-line.
-
- Once you have RT in memory, the following keys may be
- pressed to do the following actions:
-
-
-
- Ctrl-@: Screen Saver... this is used to save your crt
- (^@) screen from being "burned in" from stuff being on
- the screen for long periods of time. After you
- press this key, the screen will clear (including
- the status line), and the cursor will be turned
- off. This computer will then wait for a key to
- be pressed. After a key has been pressed, the
- cursor will come back, and control will go back
- to the original program.
-
- Ctrl-^: Pressing this key will turn the cursor into a
- (^^) solid block. The reason I put this command in is
- because I have always hated a blinking cursor.
-
- Ctrl-_: Cold Boot... Pressing this key will cause a
- (^_) message to be displayed on the status line asking
- if you want to reset the computer(do a cold
- boot). Pressing 'y' or 'Y' while the prompt is
- displayed will cause the computer to do a cold
- boot. Pressing any other key will abort the
- attempt.
-
- Ctrl-]: Clear the screen... Pressing this key will just
- (^]) clear the screen--nothing else
-
- Ctrl-\: Pressing this key will put a prompt down at the
- (^\) status line that looks like this: "Print>".
- At this prompt, anything you type will be echoed
- to the printer. You could use this to send
- control codes to your printer(note: the above
- keys still have the same affect, so pressing '^^'
- at this prompt would only turn the cursor into a
- solid block, and NOT send anything to the
- printer.). You could also use this feature to
- write notes to yourself when you don't have any
- paper handy.
-
- Modifying Ram Tools
-
- The source to RamTools is in two files, because my Public
- Domain Z80 assembler(Z8MR) will not do phased code. IF YOU
- CHANGE THE BIOS ADDRESS, BOTH FILES NEED TO BE CHANGED!!
- So, in order do change the files, you must make the neces-
- sary changes and assemble BOTH files(the code is in Z80
- code, so any Z80 assembler should be able to do it(I used
- Z80MR). AN 8080 ASSEMBLER WILL NOT WORK, EVEN IF IT IS
- CONVERTED TO 8080 CODE, BECAUSE IT USES THE "LDIR" COMMAND,
- WHICH IS NOT SUPPORTED BY THE 8080.). After that, all you
- need to do is place "EX.COM"(supplied), RT.SUB(supplied),
- DDT(not supplied), and the two hex files(RT.HEX and
- RT1.HEX) [made from assembling rt.azm, and rt1.azm] on a
- disk and place it in drive a. THE HEX FILES MUST BE NAMED
- "RT.HEX", AND "RT1.HEX". Then type "ex rtcreate". This
- will make a program called "RTN.COM", which can of course
- be renamed to whatever you like.
-
- NOTE: There are only three bytes left until you hit the
- top of memory, so to make any additions to the program, you
- will have to shrink it a lot!!
-
- Please send any changes to this program back to me, at the
- address below.
-
-
- MAKING THIS PROGRAM "AUTO BOOT" WHEN YOU TURN ON YOUR COMPUTER
-
- Note: As far as I know, this little patch will only work
- with plain CP/M. I made this really simple... all you have
- to do is put dumpx(a file dumper AND sector editor)[this
- file is supplied] onto a disk with RT, "RTBOOT.SUB" (SUP-
- PLIED), and "ex.com"(supplied). Then, all you have to do
- is type "EX RTBOOT". After it is done, reset your
- computer, and see what happens. If you do not get the
- sign-on for RT, it is suggested that you re-copy the system
- onto that disk, because the system may be messed up, and
- could mess up other things too.
-
- FINAL NOTES:
-
- Although this program has not crashed, or caused any other
- program to crash yet on my system, it is possible. So
- please test this with your software before you use
- it(especially if it is RAM-Resident). I WILL NOT HOLD ANY
- RESPONSIBILITY IF ANY DATA OR A PROGRAM IS LOST DUE THE
- USAGE OF THIS PROGRAM. If you do run into a problem,
- please notify me of the problem, and please include any
- information which you may think helpful to solve the
- problem.
-
- As far as I know, the only problem this program will create
- is messing up the screen(some programs really look weird if
- you clear the screen without it knowing you did. Also, I
- know that this program will not work with dump10(a ram
- resident screen to printer dump), because this program uses
- the same memory space(that's where I got this idea to put
- it above CP/M).
-
-
-
-
-
- For The future:
-
- For the future, I intend to have a "patch bypass" key, so
- you can enter the control chars that this thing uses for
- it's commands(being able to press "Ctrl-^" and get
- "Ctrl-^", instead of a solid cursor. I will also attempt
- to CRAM more useful commands into memory. I would also
- like to find a way to make it "patchable" so any computer
- can use the commands.
