The displays (Toppoly) are no longer in production but we have some in stock.
And, the GTA04A5 board is designed to use them. So it is just about producing
again based on the existing design.

Changing the display to a model that we can buy in any quantity from running
production needs to redesign the PCB and test and qualify that for production.

Sometimes, companies buy components and after 2 or 3 years they end production
of the devices using these components. And then, they try to sell their overstock.
There are component brokers who are experienced in getting such "old"/"obsolete"

That has not been researched - and may change every day. I can't tell if it is
easy or difficult before someone starts to really buy them. It may be just some
Alibaba search or a search for a needle in a haystack.

But *I* will not start this research before it is clear that we need them, because it
would be waste of my lifetime...
