There is nothing unique to Terasic in the DE-10 apart from the PCB layout which isn't copied even though Terasic publish the schematics for it

The DE10 is just a Cyclone V FPGA by Altera, some DDR3, a few controller chips and the rest is just noise, it's a cheap dev board

The DE10 was used for the project as it was cheap and plentiful. It was designed for Intel's FPGA college program originally and why they offer academic pricing. Terasic has never had anything to do with the MiSTer project, using a off the shelf board saves the costs of developing hardware just for the project apart for the add on boards which are cheap and simple in comparison

The idea of using the new DE25 nano whenever it arrives is for the same reasons, price, availability and resources but that all hinges on Intel's fabs really which isn't looking too promising

Terasic can't do anything about what Taki or QMtech are producing

Don't forget Heber is making MMS 2 which is a all in one solution with everything on a single PCB and they are an established UK electronics company of over 40 years

Neither Takis or QMtech cyclone V boards break any of Terasics IPs they are not 1:1 copies of the PCB even
They are simply MiSTer compatible boards with removed hardware and functionality that the project doesn't use

The DE10 is just a collection of off the shelf parts with nothing proprietary to Terasic

The QMtech board is even open source with schematics available on GitHub

The MiSTer project has a commercial license and Taki has even donated to the project direct

Terasic has no stake in the MiSTer project, The DE10 was a cheap off the shelf dev board that was released at the right time.
The MiSTer prototype used a different board

If Terasic brought the price back down to what it was early 2021 there would be no need for the cheaper compatible boards, they created the gap in the market

Robert Peips MiSTer PS1 core has a commercial license too like the rest of the project
