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.

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.

In those days, DAT and Exabyte tapes were more portable until DEC spun the DLT group out to quantum. But for a very long time 4mm and 8mm were a lot cheaper/meg. I still have a couple of working 9-track, 8mm and 4mm drives, but nothing from DLT.
I don't know why, but I'd really love a 9 track drive for one of my DEC boxes..

It is true. If you search for TK85,86,87 documentation, you'll find that
they can read TK50. Wikipedia is (unfortunately) not nearly as correct
as you would wish, lots of times...

I don't have prices right now, but I know where to find them.
Are there others here at HECnet who might need them?
I could check if we could get a good bargain if ordering several.
Yes, I could use a few.

Hello!
Why? What ate them? The snowmen outside don't. The Daleks and Yeti
don't. The Cybermen have other issues. But any of them especially the
snowmen are outside and watching you now.
