Newsflash, Rodrik Studio is presenting the PicoCPC which was made with FreddyV (PicoMEM's author) who announced it on Twitter.

The PicoCPC features :

• ROM, so can change a 464/664 in a 6128
• RAM, all mode except the mode C3 (important for at least CP/M+ and Fuzix) at the moment)
• keyboard remapping to EN/FR/ES
• Floppy disk Controleur (only work with 464 and 464+
• MEA8000 emulation used in the Technimusique vocal synthetizer (french product)
• Reset bouton

This PicoCPC is using the Raspberry Pico 2, so it could be possible to get more features in the future, like we can see what can be done with the Pico 1 used in the PicoMEM card with a PC XT. The sound of a Gravis Ultra Sound on an Amstrad CPC o.O ?
