Here are directions for using the
MMC64 with RR-Net to make backups of
Commodore 64/128 disk libary. See
below for a link to get most of the
files you'll need.
NOTE:
You will need to turn the C64 off and
on after each successful image
extraction. I am looking for a way to
avoid this, so far nothing I have
tried works. For this reason, it might
be best to use a C128.
1. Purchase a MMC64 and RR-Net from
http://protovision-online.de (In
Germany) The MMC64 fits into the
cartridge slot of the C64 (or 128).
The RR-Net attaches to the MMC64. It
has an ethernet jack.
2. Format SD-memory card, FAT 16 or 32
3. Download "Warp Copy." The software
contains 2 components. One is
WARPCOPY06.prg which is to be run on
the Commodore c64. The other component
is warpcopy.exe which is to be run on
a modern Windows PC.Together they work
to perform a special kind of TCPIP-like
network. I moved WARPCOPY06.prg to the
SD card. I installed the PC version of
the warpcopy program. You may want to
add warpcopy to your firewall rules,
allow data to pass through your
ethernet card. 3.5 Get a copy of
MMC64_Recovery_V110.zip. With this
file you can perform a MMC64 Bios
upgrade to V1.10. You will
need this to make the TCPIP connection
and to extract D64 files using the
card. Unzip and install recovery.prg
on your SD memory card. At this point
you should have warpcopy06.prg and
recovery.prg on the SD card.
4. Set up your C-64 with a 1541 disk
drive. Test everything to make sure
your drive and cables work, etc.Insert
a known-working diskette with a
program(s) on it.
5. Carefully attach the MMC64 with
RR-Net and SD card installed into the
cartridge slot of your C64. Carefully
connect an ethernet cable to the RR-
Net jack, and connect the other end of
the cable to your PC. I have two
ethernet cards in my PC to allow me to
leave the systems connected
indefinitely.
6. Activate the PC software. Change
the IP address from 192.168.0.64 to
192.168.0.101 and hit enter. This is
necessary for Windows XP because IP
.64 is not available. Experiment for
yourself.
7. Turn on the C64. If everything is
working two things will happen
1) The RR-Net's right-hand light will
shine, the left-hand light with blip
every 3 seconds or so. If it does not,
this is a clue that your network
connection may not be active. I went
into the "Network Connections" and
turned on "allow other internet users
to connect through this internet
connection" in the advanced properties
section. You should notice that your
"Local area connection" icon will have
activated if you've been successful.
2) The MMC64 Interface Bios 1.0
screen will show.
8. From the interface menu, select F1
-Start Filebrowser. Use the menus to
locate and run recovery.prg. This
program will upgrade your bios to
1.1. There has to be an easier way,
but I can't find one. There in an bios
upgrade file available, but I could
not get it to work.
9. Resart the C64/1541 drive. Enter
the MMC64 filebrowser again, this
time start up WARPCOPY06.prg.
10. Once in the program, hit N to
change the IP address. Use Inst/Del
to backspace over the "64" and replace
with 101 so that your IP is
192.168.0.101, (port 6644) just like
your PC's Warpcopy is using on the
other end. In theory at this point you
have created the connection between
the two systems.
11. Verify that there is a commodore
disk in the 1541. Using Warpcopy on
the PC
click on the "directory" button. The
program should return a diretory of
the
diskette. The time to read a disk is
about 5 seconds.
You may wish to take a few minutes to
reflect to yourself of the
possibilities!
12. Lastly, click on the Read Image
button. Warpcopy will ask for a
filename, and then perform a disk
image extraction from the diskette in
the 1541 drive to the destination file
on your PC in about 20 seconds! Here
are some useful files, plus the
start of what will be a massive D64
library, more on that later.
