I made a card that turns the GBS 8200/8220 into an internal upscaler for the Amiga 2000. It fits both GBS models. It solders directly to the back of the board. A jumper selects RGBS or RGBHV. A 3D printable case aligns it with the back of the case and has a holder for a D1 Mini Pro ESP8266 and antenna for access to GBSControl via WIFI to change settings. It works great. Add a clock generator too for best performance: https://github.com/ramapcsx2/gbs-contro ... e-Hardware
