ZX Spectrum coding experiment

I had never programmed the ZX Spectrum before so I thought I would have some sort of a quick go.

I read up lots of reference for existing Spectrum code and this is as far as I got. No fancy masked sprites or scrolling.

The graphics used in this I must add are NOT by me. They are taken from existing Spectrum games and were used purely for this coding experiment, so relevant copyright acknowledgement to those concerned.
