1530USB Datasette to PC Adapter / Re: Share your results

If you want to use your computer for watching videos etc. while recording software to cassette tapes there is a trick.

Convert the TAP file to WAV file and play it with VLC media player.Go to audio options and audio device,choose the RECORD.

That is what I used.Just an ordinary superglue.I just checked the cassette in the video.It seems it is still holding fine.Glue didn't eat through the magnetic tape.

Best way to backup your tapes is capturing the audio with the Audacity.Save it as wav file and convert it to TAP using audiotap.You don't need to change any settings at all.

Test the TAP with FinalTap or Tapclean.Tapclean is more upto date and recognizes more loaders.

Thanks to Flavio web for making this video.

If you don't speak Italian,try the subtitles,works pretty well.

I can send you another one free of charge.You don't have to return the faulty one.(Chuck it in the bin)

Or I can give you a full refund.Let me know.

That's great news.I'm glad to hear that it worked well for you.

Interestingly I only need to go as far as volume 2 for reading tapes.

That is one of the minor issues that I need to look in to.Datasette is too loud,needs attenuation.

recorded it back to a new cassette

Hello Steve,

That whine sound is normal,turn down the microphone (READ) to level 2.

It seems like adapter is not making a good contact with the datasettes read pin.

Please check your connector to see if there is any bent ones.

I've done a bit of research.Step down voltage regulators are usually one single chip.But step up boosters needs a coil and few more chips.I want to keep the original casing for this adapter.I want to keep it simple and cheap.I don't want to reinvent the DC2N.

And also I don't think 1 volt can make a huge difference,as long as it can draw the current it needs.

If you don't want cables coming out of your datasette or you don't want to drill holes,you can install a bluetooth adapter inside your datasette.I will write up the instructions when I find some spare time.

Thank you for the feedback whodan.

There are a few Italian C64 community members using the 1530USB.They preserve multigame cassettes similar to Input64.

Check out this one.

But it seems Input64 is not just games,it has magazine,apps and games so more complicated.

Did you try to extract games from the tap file using the tapclean?

I found these tap files but I couldn't split them.

This mod requires some soldering skills.

You will be able to load games to your C64 using a PC,phone,tablet or MP3 player.
You can backup your original cassette tapes to your PC.
You can record games to blank cassette tapes.

These instructions for the datasette with the board code HCT-4 94HB NP-090B
If you have a different board,post a picture of it.I will have a look if I have the same one.


Line out mod is for backing up/dumping cassette tapes to your PC.You can save it as wav with Audacity or convert it to tap with Audiotap.
You need to plug this into your PC's microphone in port.If you have a Line-in instead you might need to lower the resistance.
You will need a 100nF capacitor and a 22K resistor.If you open up an old radio,PC speakers or any audio equipment,you can salvage these parts.


Line in mod is for loading games to your C64 from an audio source.
You can plug in to your PC's speaker out and use the Audiotap or WAV-PRG  to load sotware to C64.


This mod is for recording games to cassette tapes.Straight solder on job.No components needed.
Plug this into your PC's speaker output port.

If you want all above mods on your datasette,there will be 3X3.5mm audio jacks coming out of it.
If you have a newish laptop with mic and speaker combined;

You can use a 4 pole 3.5mm connector for Line-out and Line-in for loading.But you still need another connector for the Line-in for recording.
A simple SPDT switch can be installed on the datasette marked as LOAD and RECORD.I will try to find other solutions to avoid drilling the datasette.

Two buyers reported that they had problems while backing up 45 and 60 minute tapes.

Near the end of the tape,datasette slows down,struggles to rotate.

First thing to do is change the drive belt and clean the heads+pinch roller.

If there are screws on the tape,unscrew it little bit,it might be too tight inside.

I checked the voltages and the adapter is supplying around 4.5 volts to the DC motor on the datasette where it should be 6 volts.

I will redesign the PCB and add a voltage regulator to the adapter to supply full 6 volts to the DC Motor.

That should fix this problem.

Fingers crossed.

You can use the audiotap to record tap files to cassette tapes.

Select "Convert from a TAP file" and click on "to a sound" same as the picture above.
Click OK and choose the TAP file.Press record and play on the datasette.

If you want to record T64,PRG,P00 images,you need to use WAV-PRG program.

Check out Giuseppe's video, (This video is in Italian language and you need to be a member of EDICOLA 8-BIT

Download Audiotap and WAV-PRG HERE.
Download Audacity HERE.
Download FinalTAP HERE.

For the first time you plug the adapter to your PC,you will need to setup the settings below,

1.Right click on the speaker icon and select recording devices.

2.Set the USB microphone as default and go to properties.Change the device name to "READ".
3.Custom tab,untick the AGC.
4.Set the recording level to 0 (We will adjust this setting later on.)
5.Advanced tab choose the 48000 Hz

Right click on the speaker icon and goto Playback devices.Find USB Speakers and click on the properties.

1.Change device name to "WRITE"
2.Set the volume level between 75 - 80.
3.Enhancements tab,tick the box says "Disable all enhancements"
4.Go to advanced and choose 48000 Hz
5.Spatial sound tab - set it to OFF and click on the OK below.

Adjusting the READ volume and backing up a cassette tape to PC:

Insert a good condition,original copy cassette game to the datasette and press play.

Start Audacity and click the RECORD button.

Find the microphone volume setting and slide it to the right untill it fills the screen.

After recording that side of tape save it as WAV.

Start Audiotap,click on "Create a tap file",tick "from an audio file",tick "Inverted waveform"

Click OK,choose the WAV file,OK,give the tap file a name.

Drag and drop the TAP file to Finaltap

If you get Recognized 99% you have done a perfect backup.Click on Repair & Optimize to clean it up.

After the should show all green and Recognized 100%

Click on the save as (disk icon) to save the clean tap.

Keep in mind,you don't get these results with all TAP files.It depends on the loader.You might try Tapclean program aswell.

Drag and drop the cleaned TAP to winvice emulator and check if it works.

Recording software to blank cassette tape:

TAP Files:

Start AudioTap.
Select "convert from a Tap file" and "to a sound" click OK and choose the TAP file you want to record.
Press Record and Play on the datasette.

Turbo LOAD T64,PRG,P00 Images

Browse through this website and download T64,PRG,P00 Images.
Unzip those files to a folder on your desktop.

Start WAV-PRG and choose "Convert a PRG,P00 or T64 file to a sound"

You don't need to change any settings.

Click on "Sound Card" and higlight the files,drag and drop it to WAV-PRG.

Press RECORD and PLAY on your datasette.

This is it.

Good luck.
