Bryce, well known for his great hardware projects (MegaFlash ROM box, RGB to SVideo converter, MegaROM board, etc…), released a description on how to move the ACID protection chip into the CPC Plus. If you do this modification, you won’t need the ACID protection chip in the cartridge anymore and you can just connect cartridges without an ACID protection chip to the CPC Plus.
You can find the howto in the [[AcidInside|CPC Wiki]].

A replacement possibility for the ACID protection chip was also released last year, too.
