=== X(RS)-Modul
The X-drives for the CPC 664/6128 are connected directly to the floppy port. To provide VDOS, a "X-Modul" had to be installed. This was a single-ROM board with VDOS 2.0-X and came in two versions, one of which providing an additional RS232-C interface ("XRS-Modul"). The version for the CPC 464 came with a chunky housing in which both the X(RS)-Modul and the DDI-1 had to be installed.

==== RS232 I/O Ports ====
The RS232-C interface of the -XRS modules are suspected to be at least partially compatible with Amstrad/Pace interfaces.
