ZX80 video improvements

Post by Lardo Boffin » Thu May 16, 2019 5:24 pm

Hello all

I am finally the proud owner of a ZX80. :D It works but the output on my telly (even an old CRT) is predictably poor.

Are there any non-invasive methods of improving the output? Its is such nice condition I don’t want to open the case.

By way of example there is the Chroma 81 for the ZX81 - is there anything similar for the ‘80?

ZX8-CCB can be used ;)
I upgraded the ZX80 that Richard owned. I put the ZX8-CCB in the modulator can as that was what was requested. But you don’t have to do that.

Chroma 80 interface (coming soon) according to Paul’s web site...

Thanks Mark. I will wait for the Chroma 80. I really don’t want to make any changes to this one.
