Definitely wouldn't throw anything like that away. I'll see about imaging
them sometime, or if someone has an immediate need, feel free to contact

Thanks for the link. That's unfortunate to hear, but I suppose the TK50s
wouldn't do me much good anyways. Imagine how many it'd take to back up my
two 1.2 GB Seagate Sabre drives!
IIRC, the way I did my VAXen backups was to use the standalone BACKUP

Yup, I'm aware of the owner's manual, but my question was more aimed at
"What are the common failure modes of this drive?" rather than how to
operate it. I'll see what it'll take to get my VAX connected via Ethernet.
Looks like I've got the hardware, but not sure about the software just yet.
Sounds like they're reliable enough, so I may see about reading some tapes
in sometime. A friend says I can take some of his TK70s, and another one
said I can take as many 8mm tapes I can carry. Not sure if the latter is
worth it... :)
