HP 88780 9-track tape drive

G'day,

Yesterday four geeks (including myself) had tried to convince a HP 88780
9-track SCSI drive (cleverly disguised as Tandem 5160) to accept 6250 bpi
tapes. It works OK at 1600 bpi, but refuses to admit it knows about 6250:
"mt setdensity 3" on a Linux box results in "Incompatible media installed"
error (when the tape written at 6250 bpi is loaded.)

The problem is: no docs. By playing with front panel buttons, we
discovered lots of interesting knobs to turn (CONF 40..199), but weren't
inclined to try them all. What CONF will allow 6250 bpi density to be
used? Or is it permanently disabled by Tandem-customized firmware?
