Like you know, I have open pre-orders about a new memory expansion for ALL CPC, some weeks ago.
The X-MEM is an all-in-one ROM/RAM board measuring the half of a 3" floppy disc!
It's compatible with the MotherX4 multi-slots. (can be used with your existing ribbon cable)
The ROM part is a flash memory than can be programmed from the CPC for adding common resident programs
The main advantage is to allow to customize the boot by replacing the Lower/Upper ROM 0 for a full softwares compatibility.
- 464 with switch to BASIC 1.1 and FW3.0
- 6128 with switch to BASIC 1.0 and FW 1.0
- 6128 with switch to BASIC 1.1 and FW3.x
The RAM part is compatible with Amstrad / DK'Tronics / Dobbertin expansions.
The main advantage is to allow to handle all the PAL modes (RMR) over the 512K of memory (C0-FF).
The memory should be used as a RAM Drive C and can be shared with CP/M. (here boot from FW3.13 and CP/M ROM)
The X-MEM push all CPC to the same level of compatibility.
The package includes:
- X-MEM board
- Get started! notice
- 3" tools floppy disc

I will try to add informations to this post if you ask nice questions.
I would like to thanks SyX and gerald for their precious help and support.
