Sinclair ZX80 / ZX81 Forums

I have got some rough guide prices based on a 1KG package but they are quite high! DPD £24 Parcel force £20 Hermes £15 B2c Europe £12 I normally use DPD but they are very expensive. B2C are showing as the cheapest but I have never heard of them before so have no idea how good they are. Hermes are no...

I’m sure a moderator will be along to enable your PM but in the meantime I will look at postage costs from the UK to Hungary.

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

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 ...

I eventually sent this off to be repaired. It turned out IC4 was faulty but my diagnostics software didn’t show it. Hey ho. Working nicely now thanks to Mutant Caterpillar Games.

Blimey. One or two tapes there!

Hi all I have a very nice condition ZX81 up for adoption. I fairly regularly buy zeddies on popular auction sites to refurb and sell on to help pay for stuff I want to keep. Sometimes I come across interesting ones and put them on here first. This is an issue one but is in very nice condition indeed...

Do you have other chips from other zeddies you can try in it? It would probably be worth being certain the Z80 and ROM are ok.

The 32K mod certainly looks interesting.
