BTW I have tried it on the eightyone emulator using wave loader bot It does not seem to work unless I am doing something wrong
By the way, sirmorris, have you also the program which leaves the file name, in order to use it in a zx81? please post it here
BTW, there was a guy here asking for more info on the tapes of the ZX80, In this page you can find some more on the format used: http://www.microwave.gr/giannopk/zxcomp ... nclair.htm
• Firstly I load the .o into EO, then 'save' it to a wav file.
• I then load this wav file onto a real ZX80. The problem here is that for some reason after the wav has finished, the ZX80 will not drop back into BASIC. It's as if it's expecting something to tell it that the program has finished loading. If I start playing the same, or another .wav file after a short time the computer will drop back to the BASIC prompt with the program loaded.
• I then re-save the program from the real ZX80 back to my computer as another .wav file. I then boost the amplification using Audacity (what a great program). This file when re-loaded into a real ZX80 has no issues and drops back to basic and runs flawlessly.
I really wish there was a program that could do the opposite and make .wav into .o files. Something similar to the ZX81 tape utils Java app.
It worked ok for me on the emulator, it should work ok on the real zx80 too.
The other program presented here had these issues you refer to and did not work ok. I also noticed a difference in the tones frequency
No this does not generate the correct wav files (zx80) wy the drag and drop option. However it works perfectly fine when it runs from the command line
If I remember I used audacity to play it back properly; for me from the PC headphone jack to the real ZX80 direct cable was important to amplify really a lot the signal (I think I wrote the full procedure with details here in the forum somewhere, but again by heart was 2x the waveform at 150% gain playback volume)...
