... taking risk of unsold boards ...
As if ;) :lol:
Maybe they will be sold but if so, I have to do the next batch and need to collect for that batch too in the meanwhile ...
And there will be an end of this, but nobody exactly knows when. :shock:

I'm having trouble tuning a 1.2 board using a TS1000 host. The K is razor sharp but I can't get the ZXpand banner text to display properly. If I tickle the pot I can just about get vaguely formed characters but the background is grey and noisy. Has anyone had success getting a TS1000 working with a 1.2?

Do I need to mod the board for NTSC? Going PAL isn't an option.

No the board works with NTSC or PAL same.
What if you invert the picture (jumper J7) ?
Does it work properly without ZXpand connected and when writing the screen full with a program ?

So the new ZX8-CCB-SYNC is available at sellmyretro.
It offers a sync generator which avoid black screens with ZX80 or ZX81 using FAST mode.
There is no display contents but a blank picture shown with a small line in the top of screen.
It does support stripe patterns for LOAD/SAVE as well.

See the video published here with ZX8-CCB-SYNC in action. ;)

The price for the ZX8-CCB-SYNC is EUR 14.90 and there is also an upgrade kit available with just the micro controller to be soldered on existing ZX8-CCB. This requires the latest ZX8-CCB version V1.2 and medium soldering experience to handle the smaller pitch with 1.27mm or 1/20 inches.
