Thanks for everyone's help. Hope to get this solved.

Re: Loading a program to my Minstrel 3

Loading a program to my Minstrel 3

Hi, I cannot load a file to my Minstrel 3. I am playing them from my iPad. I verified that the audio cable is good by connecting a speaker to the end of the cable. The original .p file and .wav file are here: http://isdi.com/ZX81/ I used a copy of p2wav.c, I had to do some fixes to get it to compile...

TZDuino

Is anyone familiar with this build:

Cable for ZX Keyboard

I hope this is useful to others.
