Anyways... I could be wrong about the TZ07
designation, but I
was pretty sure I remembered it right. Can anyone tell me if a
TZ07 is in fact a 1/2 front loading mag tape drive, and was it
typically a given set of densities or was it frequently only
one or two densities?
As others have said, you probably saw a TSZ07. This is a
1/2" magtape with SCSI interface. It can do up to 6250bpi
(the TSZ05 does 1600bpi IIRC). It is one of those front-loading
drives that likes to remove the tape container itself (again,
IIRC - the manuals are on Manx).
The TLZ04 would be a DAT drive (the first generation DEC did).
60m tapes only - 90m and geater will wear the heads excessively.
Easy to distinguish from a TSZ07 as your back is unlikely to
hurt if you try a "clean and jerk" style lift :-) There are
more advanced drives in the series (TLZ06, TLZ07 etc.). They
all provide higher denisties (to be expected) and like to
feed on tapes (ditto in my experience :-) [1])
Just for completeness, the TZ85/TZ86/TZ87/TZ88 drives are
all DLTs with SCSI interface. I lost track of the native
capacities over the years! I was given my TZ87 because
it was "broken" - just needed the leader slipped back
where it belonged!

[1] Both my 8mm camcorders have done this too. Is it just
me ... my TK50s and RD53/54s never gave me any problems
when they were in daily use!!
