That picture is amazing Karl it even looks brilliant zoomed up.
I'm gonna invest in a few of these bad boys.😋

Has anyone ever installed one of these inside the modulator of a ZX80 ?

Yes!

I did exactly this for a forum member. I removed the existing PCB from inside the modulator (that's the hardest part). Then fitted a ZX8-CCP. I connected the black wire (0V/ground) to the inside case. Connected the red wire to the +5V supply. And threaded the yellow wire out through to the outside via the existing hole, and connected it to the video signal pad.

I see if I can find some photos.

Ditto what Mark has just written
Fitted in the same manner as described along with a switching regulator and a ZXpand kit makes it eminently more usable,(now my football manager clone doesn't take half a day to load!!)

Great product! As suggested, I gutted the modulator box and put the CCP circuit board inside with some double-sided tape. How convenient, GND, SIGNAL, and +5V are sitting just outside of the box!

BTW, for US models the Channel 2 / Channel 3 switch can be removed now.

Hi Pokemon
do you think that there will be a ZX81CCP video output for ZX81 available in the near future again? I 'd like to use one in my ZX81 too.
