Tape back-up David Brankin, Thombury, Bristol. [Acknowledgement next to the listing: Idea by J. Evans.] I have created the ultimate tape back-up program for the ZX Spectrum. It is very reliable and can copy any program. It can even copy music. It can back-up any length program - 1000000K+ - and only takes up nine bytes. It works by taking in a signal from the mic and putting it out the ear to another tape recorder. The only disadvan- tage of this system is that you have to pull the plug upon finishing. Note that the border doesn't change colour. [Of course, if you have two tape recorders, why go through the Spectrum in the first place? Just plug the one straight into the other and off you go.]
