DOSXFER is designed to bootstrap transfer of files between an Amstrad PCW or
Spectrum +3 with a 3.5" disc drive and a computer which can read DOS discs, such
as a PC, Macintosh (with PC Exchange, not Apple File Exchange), Archimedes, NeXT
or SPARCstation.

1. Format a DD disc to 720k.
2. Use RAWRITE, dd or a similar utility to transfer the image file DOSXFER.P3D
  to the disc. DOSXFER.P3D has been ZIPped - UNZIP, PKUNZIP or gunzip will 
  decompress it.
3. The disc will now have a CP/M filesystem. PCW users should examine the file
  EDIT.ME using LocoScript; +3 users should run the file DISK.
4. The software on the disc will convert between 706k CP/M format and a DOS 706k
  format which can be read by most computers.
