Occasionally, when using Versaterm 4.0, I have found that the
cursor keys on my Mac Plus do not send the correct codes to the
host.  When I asked the Versaterm folks about this, they told me
that this problem is due to a bug in the Mac Plus ROM - machines
with this ROM will occasionally fail to identify the keyboard
type.  The recommended fix was to reboot or disconnect the
keyboard to force the Mac to re-read the keyboard ID.

Now I know that there were several versions of the Mac Plus ROM,
and that the oldest version had at least one famous bug (Mac
would not boot with an unpowered SCSI device attached).  My Plus
has this oldest ROM version, and I would like to know if any of
the later ROM versions also fixed the keyboard recognizing
problem.
