Hello again,
After my summary posting I received these follow-up comments. I'm
still going with the Compaq 35/70 because of the price. The price I got
was with educational discount so I don't think I can do much better with
3rd party vendors, but thanks for the vendor list, I always need those.
I'm sure I'll be down this road again, so next time, I'll take a look at
used equipment. Thank you for the information and advice.
Diane

Part of the price difference is almost certainly history,
but part is the amount of qualification performed. The
classic Compaq design center is Intel based PCs and servers
running MicroSoft operating systems. In that space device
vendors are expected to do all the device qualification
necessary to make sure it works. The reseller may ask
for their own Vendor and Product ID, and may some particular
features, but little in the way of firmware changes.
Digital, on the other hand, did its own device qualification
to ensure that we could guarantee it worked. This work is
more expensive and (hopefully) justifies a higher price.
For a lot of customers, this guarantee is worth the extra
price. Others don't mind the extra work to do their own
integration and will buy the original vendor version of
devices.
In a more perfect world, the Houston (Compaq) groups
responsible for devices like the 35/70 would have
shipped a few to the operating system and hardware groups
for qualification and integration as soon the merger was
complete. And, the price of the original Digital version
would have been adjusted to be better balanced. But,
perfect worlds don't exist...

Quantum manufactures all DLT drives, just as Extabyte manufactures all
8MM drives. The other vendors simply OEM the drives from them, and frontend
them with their own electronics.
The DLT7000 is supported directly under Tru64, always has been.
The 35/70 is the same drive as the TZ89.

The 35/70 drive is aimed at the PC market and is therefore cheaper.
It apparently has differnt firmware when it's being a TZ89.

According to Compaq the TZ89 has "enhanced" firmware over the generic 7000
unit. I'd suggest getting prices from a few Compaq resellers,
http://www.enterprisesalesgroup.com/default.asp
http://www.es.avnet.com/
http://www.compaqused.com/index.html
You should receive a significant discount over the Compaq price. You might
consider purchasing a used unit as an option.
Best regards,
Ed Murphy

I think you will find the only difference is the firmware. If you talk to
your friendly engineer next time he is a round he can load the Digital
firmware into the drive. I have used ATL tape libraries which Digital
rebadge, and when the ATL engineer replaces faulty tape drives he has to
update the firware to the Digital version.
Good Luck,
Viktor
-------------------------- first summary ----------------------------
Hi,
Sorry for the delay, but it took a while to research some of the
information provided. As usually, I received enough information to get it
all sorted out. Most responders said the Compaq 35/70 and Quantum DLT 7000
were pretty much the same thing. However, Alan gave me the part no. for the
DLT that is supported for Tru64, the Digital model for this DLT (TZ89). I
really didn't want to bother with modifying the ddr.dbase to get it to work
so this is the way I really wanted to go but it turns out the Digital model
is ~$1900 more expensive than the Compaq version. (I got both prices from
Compaq). Go figure. I guess I'll have to purchase the Compaq 35/70 and
spend the time to get the ddr.dbase working correctly.
Thank you to all who took the time to help me (original
responses at bottom),
Diane

-------------- original posting -----------------------------------
Hi,
I'm hoping to purchase either a Compaq 35/70 or Quantum DLT 7000
drive and I've browsed the archives and compaq web site looking for
information. I would like to attach this unit to an DEC Personal
Workstation 433au (V4.0d). So far, information appears to indicate that
this unit is not supported on my workstation. However, the real question
is, are any of you out there successfully using either the Compaq 35/70 or
Quantum DLT 7000 on any DEC workstation running tru64 unix? If yes, do you
have a working ddr.dbase entry for this unit?
Will summarize.
Thanks,
Diane

They are the same drive. The Compaq 35/70 is a rebadged Quantum DLT 7000.

The Digital version of this drive is called the TZ89. If
you can still get a DS-TZ89N-xx from us, then prefer that
version since it is the supported one. The DDR entry for
one of the others would borrow heavily from that of the
TZ89 with appropriate changes to Vendor and Product ID
strings and possibly Inquiry and Request Sense lengths.

they are the same drive (pretty much). use the DEC TZ89 template to get
best results, compression and all.

From: "Notari, Ed" <NotariE_at_usa.redcross.org>
What you have there is a TZ89, at least that is what DEC/COMPAQ calls it. It
is in the ddr.dbase. I have one (DLT 7000) and it is in my T64U 5.0a
ddr.dbase.
