DO NOT USE DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time it is unfortunately not possible to white list users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!
So, yet another replica build is about to unfold - A ZX80!

And yes, it has jumped the queue, but it should be easier to build than the Cosmac Elf II, for which I am still missing some parts. I have almost everything for the ZX80, including keyboard membrane, case and all but 3 IC's and a resonator.
Those are all coming and should be here by the time the bulk of the build is done, and I now have a ROM image too, so looking very positive. I'm hoping to have it ready for CL4

Very nice.
It'll be even better when it's finished

Back in 1980 me and my brother ordered a ZX80 and Sinclair wrote back saying would we mind waiting because they had the cheaper and better ZX81 coming out.
Ive got a ZX81 knocking around somewhere. I found a PSU for it the other day.
Cool. Oddly the ZX81 I have came with a ZX80 PSU which also works perfectly with my 2600 light sixer and 2600Jrs. Oh, and the ZX81 too

I never did see a ZX80.
I was slightly late to the ZX80 game and had a ZX81 instead. Mine came ready assembled, and I think by that time the sale of kits had waned somewhat. That little machine gave me a lot of joy until I got a Spectrum.

Good start, all the diodes and about half the resistors installed.

Having a coffee and custard tart break while I watch Usagi Electric on YouTube, then back to it

Well, a couple of hours building and I'm nearly there:

Just waiting on some missing parts to finish the build and then I can do a smoke/voltage test before I install the IC's. I was going to put a Traco voltage regulator in it, though I do have lots of spare 7805's if I can't find one.
