A Newton Apple 1 Replica?

I have recently come across this board with NTI logo and golden edge connectors. I think it's a Newton-made because it is the only replica with NTI logo and golden edge as far as I know. Can anyone help identifying it please?

 

Thank you

I recently assembled a NWTON

I recently assembled a NEWTON replica board. The green color of mine is different and the color of the silk screen letter B too. The NTI logo is also on a slightly different position. But maybe  your board is from an older batch? Where did you get it from? Is something written on the back side? If I am not mistaken there is Newton written somewhere. But i am not sure.i cannot check at the moment because I am on travel

I don't have the boards in my possession. Here are some more pictures and I'll ask the owner to send more of the back side.

The funny aspect of this Apple-1 clone is ...

... that is based on 74LSxxx ICs much as my most recent build which was subject of this thread:

 

https://www.applefritter.com/content/whats-issue-lsttl-apple-1

 

So others had the same idea to use LSTTL and were not discouraged by the naysayers. I still wonder who brought up the rumor that a 74LS161 won't work in the Apple-1. (Note this is not the same thing as the 74161 vs. 74161A issue as dicussed by Mike Willegal in his Apple-1 blog).

 

I also wonder how the builder of this clone got the ageing effect. Except for a few givaways any expert can immediately recognize as being clone-ish, it really looks old like an original.

 

Maybe he kept it outdoors for a while, exposed to the elements ?

 

If so, do the cheap stamped contact sockets still give reliable contacts ?

Pretty sure it's a Newton

Pretty sure it's a Newton based on the way the traces are layed out.
