Digging around in my junk tonight, I come across a DEC TZ875-TA 5-slot tape changer. Some googling shows it can *read* TK50 tapes! I'm playing around with it on a Linux box using native DLT IIIXT tapes on it to make sure it's operating correctly, then I'll give it a try reading a TK50. I hope it works!

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.

Its outer end which grabs the tape from the cassette is arrow-shaped. Is the "arrow" quite in order? If not, the takeup leader should be replaced. 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. Ian . 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.
