I am looking for the name of a magazine that was mainly for computer projects. I started some improvements for the

ZX81 in the early 1980's, of which, one was for inverse video( white text on a black background) this still works.

Another one I believe, was for producing a tone when any key was pressed, this does not now work. The projects was

very easy to understand with photo's of them mounted on a PCB. I would now like to finish these projects. The

magazine was printed too a high quality on gloss paper of about 30 pages with little advertising and was quite

expensive for that time. I remember buying only the 1st 2nd and probably the 4th issues and they were purchased on

one of London's railway stations. I think they soon ceased publication after a year. Mine got thrown out when moving,

old age comes round so fast. Can anyone help with the possible name, or even perhaps the circuit diagram of these

It might take a long time before he gets a reply over there. If someone here has any suggestion please post here or at

Thanks.

    I have had quite a few magazines regarding hardware (ZX81) . As said in previous posts im stopping selling items.But i have quite a bit of ZX81 hardware left and in the previous post (above) it mentions this "ZX81 in the early 1980's, of which, one was for inverse video( white text on a black background) this still works" . I have one of those boards allready made up and fully working :)

    Could it be "Sinclair Projects" which was a spin-off from Sinclair User and Sinclair Programs?

    Edit: probably not - I've just read the link in the OP.
