My zx80/zx81 clon is working
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....

Re: My zx80/zx81 clon is working
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 the internet.
My assumption was that rivets were used in the original one, inserted from above to facilitate their insertion / extraction.
In any case, it is easy to change.
Re: My zx80/zx81 clon is working
I like the red board. Most clones try to replicate the look of the original board and while I appreciate this I also think the red board is more ... honest!
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

Good job. It has more chips - did you integrate the NMI generator ?
So it is not a plain ZX80 ?

For longest time I thought the rise in the top of the ZX80 case was where the rampack would insert into the bus...
If it was redesigned maybe this would be an aesthetic improvement. Put power and video on left side and ear mic on the right.
