Hp-85B is really an HP-85?

There are more differences... the ROM in the 85B seems to include
some of the mass storage rom functions, while the 85A can't talk
to hpib drives; there is even a TRANSLATE command in the hp85B
that will modify a program created in an hp85A without the mass storage
ROM so that the program can access disk-based files; otherwise,
it will be only able to access tape-based files when run in the 85B.

Also, memory architecture might be different; I infer this from the fact
that hp explicitly warns not to use the 128K memory module in an 85A,
only in an 85B.
