but, the tape cartridges can still be bought new. The
HP-85 uses
QIC-40 tapes, the brand name being "DC-1000".
Are you sure DC1000 cartridges will work? It's supposed to use
DC100 cartridges, which are not QIC-40. I didn't think DC100,
DC1000, and DC2000 cartridges were interchangeable, despite being
the same physical size. But I haven't tried it.
