The CF drive has a 16Mbyte CF card in it and is attached to the Masters 1 MHz bus. On the right the RFS HDINIT CF_FORM ROM is installed in a Care Electronics Master ROM cartridge. I keep it in a cartridge because it is only needed when a new CF card is formatted. On the screen you can see the contents of the CF drive (copied from the 5¼" floppy disc and the output from *FREE showing 7+ MB free space. Because the interface is 8 bits wide it can only use half the capacity of the CF card. The CF drive can take 2 CF cards as drives 0/1 and 2/3.

I am planning to use the CF drive with a 1GB CF card to back up all my BBC era floppy discs.
