Commodore 64 using audio-in to record tapes on 1530

In the previous post I used audio-in on a datasette 1530 to load t64 files from the internet. Well, thats nice, but I want it a little bit more retro, I would like to record tapes from the t64 files, and then load the game from tape.

If you have the audio-in, it is easy to record that audio to tape. Watch the schematic:

To record from the audio in, we simply connect the output of IC2-2 (pin 12) to the input of IC2-6 (pin 11). I have used a switch, so i can decide if i want to record from the c64, or if i want to record from the audio-in.

So I have an audio-in and a switch on my Datasette 1530. The N stands for normal operation, the R stands for record from audio-in operation.

Well, lets see if this works. Using the same Stix game again :-)

Commodore 64 adding audio in on datasette 1530

I recently bought a Commodore 64. Also a 1541 II diskdrive (and a 1541) and a lot of floppies with games. But it is a hell of a job to search al those floppies for one game… I would like to play Stix.

Also bought a datasette 1530. And searching the internet i came across this. A way to download a t64 file from the internet, than play that t64 file with a phone (Android, tapDancer), and send the audio to the 1530, so the C64 will load the file.

It seems no guaranteed succes reading the discussion. But i gave it a try. Found a schematic.

My 1530 is slightly different, IC1 is splitted in two IC’s (LS204CB). I connected the audio in (with 100kOhm resistor) to IC1-4, pin 12 (the non-inverted input) in above schematic.

And made a RCA-connector in the case of 1530, to input the audio.

Let’s see if it works! I downloaded stix.t64, and installed tapDancer on my Android Phone.

To check the volume setting of tapDancer i’ve used a head alignment tool. Just increase/decrease till you get nice lines. I’ve used this on, Minimal Head Align.
