And all of them DEC. No IBM, CDC, UNIVAC, etc. As to what it inspired,
I can't say.
Similarly, is DLT a "dead end"? It was

isn't LTO clearly an evolutionary variant of DLT?
But DLT was used in systems made by various manufacturers. Yes, it
originated at DEC, purchased by Quantum and used on various systems. In
fact, Quantum probably made the bulk of the drives, not DEC. Being a
cross-vendor interchange medium, I'd include it.
The same for DDS and 8mm (Exabyte) media. Exabyte didn't make computer
systems, so it necessarily had to be cross-vendor. DDS is, of course,
How about the 2mm Pereos tapes? Never really took hold and used Sony
audio mechanisms. I'd call that a dead-end, not being aware of
