|  How do i get a tap file back onto tape so i can load it onto my plus4??
Hi wonder if anyone can help me?
I have a working plus four and am desperate to play icicle works on it again, old tape won't work any more so I downloaded the .tap file and converted it to a wav file, then played that out onto a shoebox stlyle cassette recorder but when i tried to load the tape it didnt work.
Have tried inverting the wave as well an still no good, any one any ideas where I am going wrong?

It is possible that the recording level is not set correctly, or the head alignment is not consistent (quite common with the Datassettes) and need to be adjusted.
By the way, I use a simple circuit that allows sending the sound output of the PC to the tape input of the Plus/4, so that programs can be transferred directly without recording to a cassette.

Some questions: does the Datassette actually work (i.e. can you record a simple basic program with it, and then successfully load it back) ? Are the programs not even found, or have load errors ?

yes the datasette works but never finds the program . I am recording the program onto a old shoebox style cassette player.
Whats this circuit you use to input the sound from the pc straight into the plus/4.

Well, then it could be different head alignment, as mentioned above, but also some simple reason like the recording having too low amplitude.
The circuit I use is basically just a simple amplifier (with one NPN transistor and a few resistors) to convert the soundcard output to TTL level; it is quite hackish, and obviously not the best method for data transfer, but it works. I use the tape signal to sound output feature of my Plus/4 emulator, and a ROM tape turbo that allows a speed of about 550 bytes per second.

Out of interest how do you convert a .tap to a .wav file. Sorry if this has been discussed before.

I'm using a program called audiotap

Audiotap does not seem to work with half-wave format .tap files, although that is probably not your problem, as trying to open a file in unsupported format results in an error message, rather than creating a bad .wav file.

| Ok what am I doing wrong.
I have saved a basic program as .tap file using Yape. When I try to convert it to a .wav file using audiotap I get the error message ".tap has unsuported TAP videotype 4294967232". So what I am doing wrong ?

You could use plus4emu instead, and record directly to a .wav file (the file need to be an already existing one, however, it can be basically any non-compressed sample format and any sample rate), without having to use Audiotap. You can also set if the signal should be inverted or not.

Hi. Ok I have installed Plus4emu and I have a dummy .wav ready to use. How do I save/record as a .wav file ?, I cannot see the option. Thanks

You can open tape files by pressing F6 and selecting the file in the dialog that appears. The tape controls (play etc.) can be accessed in the Machine/Tape menu, but some commonly used controls also have keyboard shortcuts: Shift+F9 (or F5) is play, Shift+F10 (or Shift+F5) is stop, and Shift+F12 is record. Tape emulation settings like inverting the signal in .wav files, sending it to the soundcard output, etc. are configured in the "Tape" tab of the Machine/Configure window.
