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=20
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.
