Sinclair ZX80 / ZX81 / Z88 Forums

Thanks for all the encouraging words and your time Mark! Also a rather impressive de-solder and bit of socketing there!

The new socket will help when the rest of get sent the wrong chip...add it to the parts list for the kit. In fact I am adding sockets to everything I have!

It's been a while. Is there any movement on this?

Yeah, I've been distracted with other things.

Hopefully at the weekend, I can do some more. I'll then post an update here.

Good to know I am not the only one!

I just used the "slave tape" output on my 1980's prototype (pictured at the beginning of this thread) to copy an entire tape for a friend. The clone seems to load even more reliably than the original! Can't wait to see these kits distributed, once they pass muster.

Afternoon ‪Lardo Boffin‬

Okay first, sorry that this has taken a while. Too many distractions

So after repairing my audio sine wave generator (a PP3 leaked and corroded all along one of the connection leads) I have completed some bench testing.

Along the way, I discovered another track break. Now repaired. I also tidied up a couple of other connections.
So as far as bench testing is concerned, it works fine . I'll post the results a bit later (need to convert to a forum friendly format).

Now just have to find a ZX81 cassette tape...

Also can you please send me your current address via PM so that I can return it to you.

Thanks Mark.

That's great work Mark, thank-you.

The table seems to show the unit very stable once the "lit" threshold is reached. It never occurred to me to quantify it like that; I just know the darn thing works.

Here's hoping for your problematic tapes Lardo,...
