The '''Y-MEM''' expansion made by TotO from ACME is a similar expansion as the X-MEM. The difference is the addressing of RAM and ROM

While the X-MEM addresses the lower ROM, ROMs 0-6 and 8-31, the Y-MEM addresses the ROMs from 32 to 63.

The X-MEM allows to access 512 KB RAM using the port &7Fxx. But the Y-MEM addresses another 512 KB using the port &7Exx.

Using the X-MEM and the Y-MEM together provides 1 MB of expansion RAM and 1 MB of Flash-ROM for the CPC or Plus computers.
