I have a drive that is identified on the front as a TZ85
and on the top as a TK85-AX. The drive has a non-standard
interface one the back. The interface is a high-density
40-pin connector in two rows of 10.
Does anyone know what kind of connector is on this
drive?

How familiar are you with DLT drives? I think in the case of a DLT7000 and
DLT4000 drives you've got a board that clips onto the back that makes it a
SE or Diff drive. Since a TK85 drive could be either SCSI or DSSI, could
it be that it's missing the board that makes it one or the other?
NOTE: This is just a WAG, I've not really taken a close enough look a DLT
Drive to know for sure.

There were some odd variations in the power plugs in the TZ87.
The model intended for use in the warm swap SCSI Storageworks Building
Block had a main logic board with a standard 50 pin SCSI connector and a
non standard many-pinned power input.
In comparison, the tabletop version had a main logic board with the
standard 50 pin SCSI connector and a standard four pin D power plug or the
5 pin DSSI.
Later DEC badged DLT drives I have seen had both D style and many pinned
SBB power inputs on the one main logic board so the unit could be used in
either scenario. It made me wonder why they had separate boards in the
first place since it seemed to make things needlessly complicated.

My Quantum DLT4000 has both sets of connectors and the loader
connectors, although the label says "Standalone Only".

This is an example of an early DLT drive (its the one that came after the
TK70) it takes CompacTape III carts and does 1.2GB/tape IIRC.
The connector goes to a "bridge board", one does SCSI and one of them does
DSSI. Yours apparently was hooked up to a SCSI board when installed in a
chassis because it calls itself the TZ85, if it had been hooked to a DSSI
board it would be called a TF85. They were fairly common in the 4000/xxx
series. I think I have a DSSI bridge board somewhere from a drive that had
been in one of those.

A DSSI bridge board would work for me. Do you want to sell yours?
