Well, the best remote control for retro windows systems, accords to own, prefered taste and gusto.
Already at home. Already in use
bluetooth and infrared is supported too..
Somebody show me this panel:
Stream Deck.
In my opinion, too much.
If you have an Raspberry PI in use, you can still make something similiar with it.
Using Amazon Dash Buttons with Raspberry PI has style too.
HereReally retro to control an retro windows computer : wireless keyboard or bluetooth keyboard with multimedia buttons
