Re: My zx80/zx81 clon is working

It is Eva rubber.
This type of material is sold in sheets in paper shops or craft stores.

But they don't burn 25 and 27 volt Eprom.
G540 can burn 25V EPROM.

Re: What is the going price to have EPROMs burnt?

I think it's not worth making an EPROM programmer. A new one for 8-bit EPROM is worth around € 30 on ebay.
I have this (G540):

But this other one I think still works better and cheaper (TL866CS):

Re: My zx80/zx81 clon is working

Good job. It has more chips - did you integrate the NMI generator ? So it is not a plain ZX80 ? ;) Not, it is something more, you can convert it in a zx81 with the selector in the bottom side. I think you will like the next pictures. ;) https://lh3.googleusercontent.com/C0irD_NNqt6NFz0AH4WDAwH8p2lR...

Re: My zx80/zx81 clon is working

In my case, it is not only a zx80 clone, then it is not possible to replicate exactly route of the board, and due to it, there are not reason to make a exact replication of the board. And the board in red is nice :D

Re: My zx80/zx81 clon is working

Looks nice - although anyone else spotted there is only one W button (it is upside down!) and 2 rivets used instead of the other 2 W buttons.... Thank you for your comments. I have not access to any zx80 with the rivets/W buttons, and it is really dificult to find any picture of a complete zx80 in ...
