Hi all

Any progress on the PCB? I have ordered all of the bits, although CPC have only delivered about half of my order and are telling me I have had it all, so am nearly ready to go! Well, except for the shielded cable but I suspect I may just steal a cassette cable for that...

TS 1000 iss 3, ZXPand AY, ZX8-CCB & ZX-KDLX

sirmorris?

There are 3 "firm" hats in the ring, and my wishy-washy expression of interest which I will now firm up. So that's:
  • Lardo Boffin
  • Dim_75
  • gammaray
  • TMAOne
Is the diagram capture from the article usable, or do we still need someone to design a new board?

I have a heck of a time finding mono shielded cable. Everything today carries stereo or better. I finally found a couple of long mono patch cables at a hamfest, so I currently do have a limited supply, but sheesh.

If "in the hat" means interested in getting a pcb then I'm definitely in. I need four pcbs. One for me and three for friends.
Kind regards Paul
In theory, there is no difference between theory and practice. But, in practice, there is.

Will a cassette cable for the ZX81 do the job?

Dim_75 picked up the glove I thought. I was waiting to see what happened there!

Sure it would, it's made for that after all. It's just a shame to carve up a vintage Zeddy cable.

I've managed to find some Chinese ones on eBay Canada now. (I looked for "mono shield mini plug".) I'll buy a couple of 3' patch cords and cut them in half.

If you don't want to source cables, an alternative would be to install female sockets in your project box, which would allow you to connect and use your trusty ZX81 cables without the knife.

I just found these on UK eBay

https://m.ebay.co.uk/itm/MONO-3-5mm-Min ... Ciid%253A2

No mention of shielding that I could see but probably no worse than the original ZX81 cables.

I like the idea of female jacks so you can use the ZX81 or other cables you want... I seem to have plenty.

As a kit you can mod like you want?

But do we have to use batteries... then the power jack "should" be different and an option. :twisted:
