Never mind, I asked for help in the series80 Yahoo group, and this is
actually the right package. My problem came from elsewhere (issues in making
an error-free 5.25 HP-formatted floppy, its fixed now). The disc image below
has both the HP86/87 and the HP83/85 versions on it. Works great, now my
HP85 can be a cute serial terminal. Thanks Jay W. for the pointer to the
software package, I had been trying to do this for a while.
