Using only a computer and a tape recorder you can copy the old datacasettes on to your computer. Then you can either distribute the information on the datacasette or copy it on to a new tape.
Step 1: Supplies
A tape player/recorder
A male to male mini sound cord
A Commodore 64/128
A datacasette reader for the Commodore
2 cassette tapes (or 1 cassette and 1 tape adaptor)
Step 2: Make a Program and Put It on a Tape
On the Commodore, make a program. If you don't know how just type this:
10 PRINT "HELLO WORLD"
20 PRINT "I LIKE THE COMMODORE 64"
It will then tell you to press record on the tape. Make sure a tape is in, then press record. The screen will go blank for a while. When it comes back the tape is done.
Step 3: Get the Computer Ready to Record
Now you will need your computer and your tape player. I use Window Vista. It is still possible to do with a different operating system.
First, connect your tape player's headphone or speaker jack to the computer's microphone or line in jack.
Next, open up a sound recording program:
Windows Vista - Sound Recorder
Other versions of Windows - Voice Recorder
If you can set quality in your recorder, set it to the highest.
Step 4: Start Recording
This step is pretty easy to figure out what to do.
Put the tape in. Press record on the computer. Press play on the tape. Wait until the section of the tape that you want is done. Press stop on both tape and computer.
Now you have a copy of your tape in digital format.
Here are mine:
Step 5: Copy It to Another Tape
Now you will take the headphones or speaker jack on the computer and plug it in to the microphone jack on the tape recorder.
Play the new file on your computer and press record on the tape recorder (make sure a new tape is in). When the file is done playing press stop on the recorder. Then put it in the Commodore and type LOAD. Then press play on the tape reader. When it is finished loading type RUN.
Put the file on a computer or mp3 player. Connect the digital device to a tape adaptor (or CD to Tape adaptor) and put that in the Commodore tape reader. Type LOAD and press play on the digital device at the same time you do the tape reader. Click pause as soon as the tape player stops. Press play again as soon as the tape player starts reading. When it is finished loading type RUN.
Step 6: Congratulations Your Done!
You now have three copies of the program you made. Two tape copies and one digital copy. This method allows you to make programs and email (or file share) them to your friends. Then they can use the second part of the intructable to copy them into their Commodore.
