There is one other known bug that I consider serious: using the KGET
to get a zero-length file from a PC (via the serial cable) will clear
the machine!  Fortunately, one can get around this by using RECV
instead.  Also, I believe this is only in revision A (forgive me if I
have gotten the details wrong; my bug list is not in front of me).

My hat is off to HP!  I don't think the bugs will stand in my way,
although it is nice to know that HP will replace the machine if it does.
