The RCade Display Adapter is a hardware device that allows driving an
Arcade CRT display via the GUD protocol. Currently it spoofs an
existing GUD VID/PID pair. However, now that it has its own pair
assigned, it makes sense to add this to the list of pairs that GUD
supports natively.

That's pretty cool. Are these devices somewhere available for purchase?

Hello,

They are not. I used to sell other hardware devices a few years ago but
found it took just a little too much time. Since they're open source,
maybe someone else will sell them eventually.

Thanks,
Sophie

Hi,

Sorry for any delay

Looks like Thomas got to it before I could, which is great

It's quite exciting that other people are using the gud driver, since
until this point it has tended to be a lesser-used one, so I am glad
people are using it.

Thank you for the patch

Ruben
