Just for clarity, it's not for sale, just acknowledging that there is one around.

I don't know why the DSSI interface was dropped, but I guess the SCSI drives sold better especially to the Alpha customers.
This was about the time DEC sold off DLT to Quantum. As for other applications of DSSI, DEC was going through a lot of big changes in the mid-1990sresulting in them adopting a lot more industry standards, like SCSI and PCI. It was likely cheaper and more effective to adopt newer SCSI tech from QLogic, Symbios or Adaptec than develop a newer higher-speed DSSI standard. SCSI was al-round faster than DSSI also and new Fast SCSI-2 blew it away. Guess it was just progress?

TK50Z is a SCSI version as the TZ30 is as well.
I have never seen a TK70 drive with another interface than the QBUS controller TQK70 or the BI bus controller TBK70.
The two generation of DLT drives after TK70 has had either SCSI or DSSI interfaces e.g. TZ85/TF85, TZ86/TF86.
Then the DSSI interface was abandoned and all the rest of the DEC branded DLT drives had a SCSI interface only i.e. TZ87, TZ88, TZ89, TZ90.
I don't know why the DSSI interface was dropped, but I guess the SCSI drives sold better especially to the Alpha customers.

Tape leader is fine on this drive. The problem with this cartridge is the spool inside the cartridge jammed and wouldn't rotate causing the drive to not rewind.
Ok. Cartridge failure, then. Could it have been accidentally dropped? I've seen several times DLT cartriges fail after been dropped on the floor.
You can also read a TK50 tape with a newer DLT drive like TZ85, TZ86 and TZ87.
Is this true? According to Wikipedia http://en.wikipedia.org/wiki/Digital_Linear_Tape a CompacTape I can only be read by a TK50 and a TK70.
Can anyone confirm or deny this? I have some newer generation DLT drives, but none of them admit to being backwards compatible that far.

I'm not sure if others than DEC branded DLT drives (TZ85,TZ86,TZ87) can read TK50 tapes, but DEC drives sure do.
Even the front of the drive has leds which indicate which formats the drive can handle.
Like Johnny said, Wikipedia articles aren't always the complete truth of the topic.

It's in the naming scheme. TK = DEC interface, TF = DSSI, TZ = SCSI,
TU = massbus, TA = SDI, etc. I've personally never seen a TZ85/86/87,
but if they exist, and conform to the naming scheme, they're SCSI.
Oh wait, duh, I'm half asleep. I have indeed seen them, at least the
TZ86 and TZ87, as I HAVE some here in those nice little half-width tape
changers. They are indeed SCSI.

Some of the later TZ8x drives can be found banded as other brands under a DLT model rather than a DEC model number. For example, I have a Compaq DLT4000 20/40 GB drive that's exactly the same hardware as a TZ88 but the badge on the front is different. It works just fine with OpenVMS :) Alas the 88 is too late to read TK50 cartridges... I think.
