- Formerly, the floppy controller buffered an entire diskette image
in memory using the unit buffer, and flushed it out on detach or
shutdown. This worked well enough, but it's better to have the
device use the SIMH disk sector read and write routines and
behave like a true disk.
- Read Only (Write Protect) logic has also been enabled in the
floppy controller, allowing users to mount images that do not
have write permissions.
- The IF (Integrated Floppy) and ID (Integrated Disk)
device names were poorly chosen. They conflict with built-in
scp commands and mess up the help system. This commit
changes them to IFLOPPY and IDISK, respectively.
NOTE!! THIS IS A BREAKING CONFIG CHANGE!!
