Thank you all for your interest and feedback on Retrotronik products.
Unfortunately, a small batch of 5 cards was sold from which at least 2 cards shells were manufactured using a wrong (older) printing file.
Because of this, sales are suspended until we can make sure this will not happen again and until we have complete and perfect feedback from both buyers and testers.
We’re getting good feedback so far, so I’m confident we will resume sales soon.

I want to thank Bob and Kiwi for their positive attitude, care, and availability.

Once we have any news on the sales, we'll announce it here.
Meanwhile, feel free to ask any questions about the products or to make any suggestions.

Thanks for the detailed update João. Much as I only require a 128k card, I will probably purchase a larger card too once you have production up and running again.

The main reason I don't use cards larger than 1Mb is that I currently have a preference for Filer48 as my device browser as this makes use of covered ports no different than using a typical desktop file/folder explorer. It also integrates well with SpeedUI as it uses some of SpeedUI's 'technical plumbing', which means that the overall storage utilistion is reasonably efficient. Unfortunately it doesn't function with Port 2 storage lager than 1Mb, and it has to be installed to Port 0 or Port 1.

All of this is academic as I currently have to swap between SpeedUI's matrix utilility and Filer48 as having both loaded with the rest of my SpeedUI modules in Port 0 only leaves approx 30k of OS RAM, hence my my need for a 128k card for Port 1.

The reason I'm providing this use-case information is in the hope that you're not priortising larger format cards over the 128k cards (as I suspect these are the bigger seller). For power users, a 128k card in Port 1 is essential if you want to use Meta Kernal or SpeedUI. And using a 48 without either of these OS options is akin to swimming in a pool of honey!
