Re: Looking foir a TS1500

I have bought two. And since there are so few of them they are more expensive. I think that the fact that they are the "better" TS-1000 design points to the reason they are more valuable. In my opinion , this means that if Timex had come out with these first, they would have caught on and possibly c...

Re: How bad was the wobble on the zx81

My opinion, having owned one in 1982, was that: If Timex had introduced only the Timex Sinclair 1500 first which had a "workable" keyboard, and 16K memory built onto board, it may have fared far better.

Re: "Mageco" disk controler. [infos, Docs wanted]

I think we are missing a piece on the back of ZX81...no?

Re: "Mageco" disk controler. [infos, Docs wanted]

Would I be in error to say that the electronics use a 3.5" PC floppy disk drive?

Would I be in error to say the only electronics necessary is the previously published schematic?

Re: Improving Timex/Sinclair Tape Loading

I am going to see if I can make a PCB for the people in the States before anyone else gets further on this...

Shipping is cheaper on the continent.
