DigiDOS
The Ultimate DOS enhancement
Package for the 64!


DigiDOS is 4 powerful DOS systems all integrated into 1
powerful package.
Speed up your 1541 2000%. You used to load programs at
less than 2 blocks per second, now load them at almost 40
blocks per second! (DigiDOS speeds up all disk functions.)
The real time monitor feature allows you to examine any
program while it resides anywhere in your 64!
The hardware-software combination of the GCR Nibbler makes
it the most powerful copier available!
The DOS wedge reduces commands down to 1 or 2 keystrokes,
without using 1 byte of C64 memory.
We know you will agree — DigiDOS is the ultimate DOS
package (and with the flip of a switch you can return to the
original unenhanced DOS).

Introduction

Welcome to DigiDOS, the powerful DOS enhancement for
your C-64! DigiDOS is a powerful utility and versatile aid.
DigiDOS will provide you with a DOS wedge, a real time
monitor, GCR Nibbler and the fastest disk loading speed of
any DOS enhancement system on the market. To top it all off
- for single file programs we present the special DigiDOS
format that will increase loading speed 2000% (an incredible
40 blocks per second).

-----

The DOS Wedge

Perhaps the Most useful feature of DigiDOS is the DOS wedge.
This wedge is designed to make loading, saving, reading
directories and other DOS functions as convenient as
possible. In this section we will examine each of the
enhancements.

Loading a program is much easier with the DigiDOS wedge. You
can load a file simply by typing LOAD “filename” (return).
You do not have to type in the ,8,1. The SAVE command works
in the same format. If you want to load and run the first
program on the disk, you can just press (SHIFT) (RUN/STOP).
You can also load programs with the Function Keys. It is a
matter of preference.

Function Keys
(Fl) = List Lists a basic program
(F2) = ML Monitor Enters ML Monitor
(F3) = Run Runs program in memory
(F4) = Off Disables the DOS wedge
(F5) = Load Loads first file on disk or file name on selected line.
(F6) = Save Save a file in memory
(F7) = Directory Displays a fast directory
(F8) = Switch Switch the DOS wedge from drive 8 to 9 and vice versa. If you switch to drive 9, then all the DOS wedge commands automatically are active on drive 9 until you switch back.

Other DOS functions
@R:newname=oldname Rename a file
@S:filename Scratch a file
@I Initialize Drive
@V: Validate Disk
@N:name,id Fast Format a new disk
@* or @$ Read Directory. Same as F7
@T:filename Lock/Unlock file toggle
@8 or @9 Assigns wedge. Same as F8
@ Read Error Channel

Special Commands
CTRL-(English Pound) = Text screen dump to printer
! = Unew BASIC

-----

While reading a directory (or program listing) you can
stop the listing (for good) with the Run/Stop key. You can
pause the listing with the C= key. This will pause the
listing until you release the C= key. If you want to pause
the listing for a longer period of time, you can mash the
CTRL key and the C= key at the same time. To resume listing
in this instance, press the CTRL key.

Reset Commands

If your 64 crashes, you can normally rescue the program
with all the variables intact by holding down the Run/Stop
key while you hit the reset button (either your own or on
the DigiDOS cable).
Some programs do not allow you to reset the computer.
However, with DigiDOS, you can reset them by holding down
the space bar while hitting the reset button.
Also, by pressing the C= key and the reset button, you
can jump DIRECTLY to the DigiDOS monitor with the program
still intact.

CTRL Ins/Del - Escape Quote mode (same line)
?$xxxx - Hex convert (Example: ?$1000 will give decimal equiv of $1000)
?%xxxx - Binary convert (?%011 will give decimal equiv of 011)

-----

The Utility Disk

Included in your DigiDOS package is the DigiDOS Utility
disk. This disk is not copy protected and we suggest that
you make an immediate back-up and put the original away for
safe keeping.
To load any of the DigiDOS utilities, insert the
Utility disk and smash F5. The Main Menu will load, and from
there you can access any of the utilities on the disk.

The Nibbler

The DigiDOS Nibbler is for making archival backups of DOS
protected software. Although the DigiDOS nibbler appears
very simple in design, it is actually a very powerful copy
program. Using the special parallel routines of the DigiDOS
system, the Nibbler will archive programs that others
cannot.
The Nibbler is a single disk copier and all other
peripherals should be disconnected when attempting to
archive a disk. Also, be sure to have your source disk write
protected. The DigiDOS Nibbler will not read the source disk
until you have write protected it. This is done because the
Nibbler writes very fast, and there is not much room for
error.

Single Disk Copier

Also on the DigiDOS utility disk, you will find a
single disk copier. It is for making copies of unprotected
disks and some protected. It could not be easier to use. If
you only have one drive, we think you will find this copier
very useful because it is very fast for a single drive
copier.

Setting up a special DigiDOS formatted disk

I have the need. The need for speed...

— An Anonymous 64 User –

DigiDOS will load multi-file programs and commercial
programs faster than any DOS available for the 64, but for
single file programs we have a special DigiDOS format. Using
the DigiDOS parallel system and our special software, you
will be able to achieve loads that have never before been
imagined on the 1541 drive. You will be able to load a 200
block program in just a few seconds, and a 40 or 50 block
program almost instantly. Setting up a DigiDOS disk takes
only a few minutes, and is well worth the effort.

The Formatter

The first thing you must do is to format a blank diskette
with the special formatter. Any information previously on
this disk will be lost.

-----

Program Copier

This program is for copying single file programs to a
previously formatted DigiDOS disk. Once you have copied them
over to the specially formatted disk, they will load with
amazing speed every time you stick the disk in the drive.
Once a file has been copied to the specially formatted disk,
it will read "0" blocks. That is because a DigiDOS disk uses
a special directory format. Once you have loaded the special
copier, insert the disk that contains the program you wish
to have load fast. The directory of the source disk will be
on the screen. Simply scroll to the program you wish to copy
over, and select it. The copier will read the program into
memory. When prompted, insert the specially formatted disk,
and the program will then be written to it. Now, reset your
64, and stick the new disk in drive 8. The program will now
load at amazing speeds. Once you have copied the program
over, you never have to go through this procedure again. You
can put as many programs on the specially formatted disk as
space will allow.

NOTE!

It should be noted that the DigiDOS formatter and copier are
only for setting up a DigiDOS disk. The formatter is NOT a
regular formatter, and the copier is NOT a regular file
copier. Also, DigiDOS disks are only compatible with 64’s
that have the DigiDOS system installed.

Monitor Commands

 
M 1000 ff - Enters the hexadecimal value $FF at
memory location $100
M 1000 - Displays memory in hexadecimal starting at location $1000
S"filename" 1000 2000 - Saves the contents of memory from $1000 to $2000
L"filename" 1000 - Loads memory starting at $1000
G 1000 - Execute the program starting at $1000
@ I0: - Sends the command following the @ to
the disk drive
Scrolling

Fl    Scroll current screen backward in memory 40 bytes
F3    Scroll current screen forward in memory 40 bytes
F5    Scroll current screen backward in memory 16 bytes
F7    Scroll current screen forward in memory 16 bytes

How to use the Monitor

You may enter to the monitor in the direct mode by pressing
the F2 function key. After entering the monitor you can
examine any byte from $0000 to $FFFF by using the function
keys. You can switch off all the chips except the Kernal
ROM. You will also notice that in addition to the
hexadecimal dump at the top of the screen there is an ASCII
or text dump at the bottom of the screen. This scrolls from
left to right so that you can read any ASCII text that may
be in memory. If you wish you may shift from upper case to
lower case by using the commodore and shift key. To exit the
monitor you press the X key this will put you back in the
normal mode.

Debugging with the Monitor

One of the most powerful features of this monitor is the
ability to enter the monitor from a running or crashed
program. You may enter the monitor from a running program by
depressing the reset switch while holding the commodore key
then release the commodore key after the monitor comes on
the screen then you may examine, save, load or alter the
memory contents of any area of memory other than the ram
under the Kernal ROM. To exit the monitor press X.

-----

Example

Program "x" loads with an autoboot then proceeds to load
files to several other parts of memory then waits for key
press after the files are loaded.

You wish to combine all of these parts into a single
program.

Step l

Load autoboot and wait till program is in memory

Step 2

Stop program by pressing reset and the commodore key.

Step 3

Examine the memory and use the s command to save the portion
of memory that contains the program.

Step 4

Exit the monitor using the X command. You may then load the
program you saved for disassembly and debugging.

Special Notes

Using DigiDOS with a second drive

To use a second drive with DigiDOS, just connect it in
the normal way. Although, your second drive will not have
the speed your enhanced drive 8 will have, it will function
as a normal drive 9 within the DigiDOS environment. Even
though it will not have the speed, you can use the DigiDOS
wedge on drive 9. For more information on this, see the
section on the DOS wedge.

DigiDOS and modem use

Because of the special routines that DigiDOS uses on
the User Port, it is not compatible with a modem or any
terminal programs. To use a modem/terminal with DigiDOS, you
must disconnect the drive from the User Port, and also
return to the normal 64 mode by resetting and flipping the
switch.

Compatibility

DigiDOS works with 99% of all software. If you do
happen to find something that will not load under DigiDOS,
try a few of the following ideas. Remember, you can always
make DigiDOS disappear by flipping the switch and resetting,
and in some cases disconnect the parallel connector. Try one
of these first however.

1) Load "filename",8

It could be that the program you are trying to load
must be loaded with a ,8 only. DigiDOS attempts to load
programs with the
,8,1 extension.

2) Load "filename",8,2

The ,8,2 extension in DigiDOS means to load a little
bit slower than the normal DigiDOS mode. You can slow down
one more notch with the 8,3 extension.

3) It is possible that the DigiDOS wedge (not speed
routines) could interfere with some load attempts. You can
turn the wedge off by hitting F4.

Try these hints before turning off DigiDOS completely.
DigiDOS works with 99% of all software.
