Just in case that somebody need or want to improove his picture at home.

I'm always looking for more crystal clarity

Payment sent.

Maybe you can get a ZX81 fortune teller with this circuit.

Just wanted to say WOW and thanks! I put one your boards in one of my ZX81 and the picture was incredible!

Now it's back - better than before.
ZX81SCP synced picture version beats the ZX81CCP (crystal clear picture).

Oh rats... AFK and missed it. Are you going to do another run at some point?

Yes, shortly.
Planning to do a cheap (simple) version of it without inverted picture and without sync generator but with the amazing picture quality.
And plan a new luxury version which keeps the picture content - not just an empty synced screen.
That would be fun and that would be a nice add on for all ZX80 around to have a stable picture during running program.

Hi!!, any pieces on sale?

The new (more simple) board ZX81CCB is coming.
In about one week or 10 days ...

After the early death of my first TV ( 35 years of age , bought from my first pocketmoney) I need this device too to make my ZX81 run on newer TV's!
