This VAT limit of 15 GPB is for UK, and in the rest of EU how it work? And if I send to someone outside of the UK and then he send it back to the final destination in the UK? I do not know if it's a good idea, but is just an idea
And there would be no problem in keeping the price of JOY81 in 15 GPB but plans have changed, sorry.
I will not produce the ZeXtender and the JOY81 in slot card format anymore

. Due to the low number of people interested (only 13 in Brazil) and the high cost of production of the two boards, I decided that I will produce the JOY81 only in the traditional format with the edge connector and the piggyback extensor (see picture below). Production costs will be lower and the risks involved will be dramatically reduced for me.

I'm not a business person and I do not expect to make money with it, but I hope to get enough to pay the production costs. I developed this interface and would like to share it with other ZX81 enthusiasts because it is very clever and functional, now there is no game that I can not use the joystick to play it
I sincerely hope that we can find a solution that satisfies everyone.
