I could do a calculation, think the board has approx. 75x75mm size, double sided.
So how much boards are sure to be sold ?
Are the 13 guys from brazil sure with the latest changes ?
Minimum 10 boards would result in EUR 15,00 per board (board only)
Minimum 15 boards would result in EUR 10,00 per board (board only)
Minimum 25 boards would result in EUR 7,50 per board (board only)

Well, these are about the same price I got here, I'm still negotiating with suppliers and hope to get better conditions to manufacture the boards. Once I have a firm position I'll let you know. Thank you very much.

So I think the best is if you do the production of the boards and send only boards to Europe on a per customer base in a simple or padded envelope.
So there wouldn't be a problem with customs and shipment is cheap.
I think programming of the GALs could be done here as well as many in the forum have programmers.
But I wonder why you choosed the 6116 RAM (2k x8) on your board ?
This is hard to get and a little bit expensive in comparison to the 6264 (8k x8) - even if you don't need all of it.
For me is okay as I yesterday accidently bought one over eBay for about EUR 7,00.
But I can buy the 6264 RAM for EUR 1,50 on nearly any electronic shop of the world.
So for a new design I would be careful in using old chips if not really needed ...

I think that maybe I can send tha GALs and the SRAM with the boards in envelope without extra cost.

I'm sorry, probably you have not seen this:

No have not seen but the seller seems to be (temporarily) not listed (no items) due to to many negative feedbacks.
Or maybe you did buy all 6116 from him.

Any news about the Joystick interface ?
I want to have one to start playing on my ZX81 ...

I would be interested in any hardware for the ZX81/TS1000! I'll buy one - let me know.

Hello to all!
Lately I have not had time to Zeddy activities, so my silence. Sorry.
20 interfaces were built, 17 of which were sold in Brazil. I still have 30 boards available and sufficient components to assemble at least 10 more intefaces (If I can make time for this
).
Next weekend I'll check the conditions to shipping the interfaces to EU. Until then, see some pictures:

Hi kmurta,
I want one too
Maybe You can offer the pcb and the parts (incl. pre-programmed GAL) - so buyers can assemble and solder this themselves.
Best regards from Germany
