This short video displays the text file for PD(?) software utility RAMdisc 2. This utility will give (with a hardware memory expansion) a memory drive on the CPC - Drive M - which could be used in a similar fashion to a physical disk drive.

I don't remember that too. Usually, RAM Disc is drive C. (shared between BASIC and CP/M).
He must have been familiar with the PCW - the memory drive on that computer is also Drive M.
Disc'O'Magic (DSK or ROM) use RAM Disc with C letter, but I have not tested if it support on M too?!
