John,
I have a lead here on a TF86-BX that I'd like to
take up
but while the seller says it is indeed a TF86 (DSSI), the
drive has labels on it that say TK86.
My question is: are these in fact the same thing?
I can't recall hearing of a TQK8x controller, in support
of his claim.
Yes, this is a DSSI drive. There is a SCSI version of it, the
TZ86, which basically includes the SCSI-to-DSSI board. I have
several TF85's of both types... very nice drives. The 86's and
87's are higher capacity- I believe *but am unsure* that the
87 is SCSI-only.

When the T?8x series started out each drive had three
"personalities". So you had the TF85 (DSSI), TZ85 (SCSI)
and TK85 (typically attached to HSC - I cannot remember the
exact interface used).
The Tx85 and Tx86 could read TK50/TK70 media but
could not be used on the earlier controllers (so
there is no TQK85 controller).
I don't think the DSSI drives went beyond TF86.
The Tx87 was the last drive to have read compatibility
with the older TK50/TK70 media. The TK87N lost that
ability (basically a cost-reduced TK87) and the 88s
and higher continued the trend.

I haven't heard of a TK85. If it attached to an HSC, and it
wasn't DSSI or SCSI, the only other obvious choice would be
STI. Most STI tape drives had models of the form TAxx, such as
TA79, so I would have expected an STI model of the Tx85 to be a TA85.
But perhaps it's an exception to the rule.

That 3rd personality could well have been a TA85 (rather
than TK85). I don't have the relevant Sales Update
articles to hand, and they seem to have vanished from
the HP website (or just hidden themselves well).
