*** CP/M Plus Master Disk for CPU280 ***

This is a basic CP/M Plus system disk.  It contains all of the
CP/M Plus files normally provided by Digital Research as well as
a few supplemental files to format disks, edit files, etc.

Notes:

- The 1.44MB format works much faster with a physical interleave of 2:1.
  FORMAT.COM format #63 will do this automatically if you format the disk
  using the CPU280.  If you format the disk with Windows/DOS, you are
  probably getting 1:1 interleave which is sub-optimal.  Ideally, you 
  should format the disk using the CPU280 using format #63, then write
  the image to it using RawWrite or dd via Windows/Linux.

- The original v1.13 ROM Boot Loader has a bug that prevents booting 
  directly from floppy disks.  The RetroBrew Computers releases 
  correct this bug and should allow booting directly from the disk.

- The "Boot Drive" and "Drive Search Order" settings in the CPU280
  ROM setup are propagated to CP/M 3 at boot.
