He has relisted that many times... ZX80s normally sell for upwards of £150 - but that one is in excellent condition I must admit - they are normally yellowed cases, with cracks and corners missing...
As for mine, it was previously used by a water company for calculating flows.
It is yellow (apart from 2 white stripes where something has been attached to it!).
It also has a few chunks missing on the corners and cracks.
It also has some extra holes in the top case (where something was obviously screwed to it!)
Andy did repairs to get it working for me.
I have also made a replacement heatsink for the machine (as it was missing this!)
I've helped people from Portugal, Spain, U.K. and the Netherlands get items shipped from here to them. If you ever need help, you know how to reach me.
