A new hardware interface by TotO the hero which should be available for Christmas on Cent Pour Cent. See below, it's just a copy and paste of this site about the X-mass.

Shown at the ReSeT #18 event in France, the X-MASS is actually work in progress.

This last MX4 expansion is a mass storage. It embed a 128MB turbo flash drive for storing thousands of files into your CPC and definitively make it autonomous as no PC is required to configure and use it.

Developers will be able to work on more ambitious projects requiring megabytes of resources and code to be compiled, breaking the floppy limitation. Used in conjunction with X-MEM, the cross-dev will be no more the only issue for the future.

Last but not least, users will be able to copy, load, save, run files faster than ever !

By the way, the X-Mass can already be used with SymbOS.
