We're any of the other DEC drives released in a scsi version?

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.

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...

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.

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.

Fair enough. We had DLT in our lab in MRO, but I personally tried to stay away from it as I preferred 8mm and 4mm [i.e. my Alphas that I used had them and a TS08 -- although IT used Legato to DLT behind the scene.

By the time I grew out of using tape, I switched to DVD and finally just enough RAID/JBOD with replication to not bother with tape except for readonly.

The Wikipedia page specifically lists items as read/write and read/only. TK70 appears to be the highest read-only for a TK50.

IIRC you could >>read<< them, just not write them.

I could use some for TK50, TK70 and TZ87, don't (yet) have any others.

Didn't remember to tell that anyone who wants takeup leaders, please
specify for which drive type (TK50/TZ30, TK70, TZ85, TZ86, TZ87, etc) you
need a takeup leader. They are slightly different depending on the drive
type.
It would be good to know how many you want as well.

Kari
