Improving Timex/Sinclair Tape Loading

[Lardo Boffin]

I never make mistakes. Once I thought I'd made a mistake, but it turned out I was wrong.

Seriously though, I'm glad to hear another dubber is on-line. Can't wait for Lardo to turn it loose on those "unrecoverable" tapes and see how many can be rescued.

It will probably be May before I can try anything. Most of the stuff in my house is going into storage while I move. Argh.

Well I assume the thing's working, but I admit it's only by trial - I haven't scoped anything out. I notice that I can make the LED light if I poke my fingers near certain components - I guess it's quite finely tuned?

* update - and a flick turns it off and on again. I think there's a screw loose. The board might have a fault too.

* update (2) - it's the cable. Sigh. Broken or intermittent conductor.

Sinclair games tape 1 - no hope for this.

Input at the top in yellow, output belue.

It'll be interesting to compare to another working board.

That is a big difference. Is there a program to manually construct a file based on a human visually inspecting the original file and losing a week of his life.

Hi Mark

Just wondering if you have had chance to look at my mess, sorry dubber attempt to see where I went wrong?

What is snow?

Oh yes, I dimly remember snow in Texas in 1969, 1981, 1989, 1998.

We get it about once every 10 years whether we need it or not. And some people get their car replaced at the same time...

No worries. Know what you mean about the snow. Nearly three hours to do 25 miles. That will teach me to own a BMW.

So after looking at it for far too long, I discovered a big problem. It was staring me in the face.

So can anyone tell me what is wrong in this picture:-

CPC part number SC13781

(The IC pictured came out of the bag in the photo with the CPC part number).
