That picture is amazing Karl it even looks brilliant zoomed up.
I'm gonna invest in a few of these bad boys.
ZX81CCP video output for ZX81
Re: ZX81CCP video output for ZX81
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.

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb

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.
