I recently acquired a clean TTI (Transitional Technology) 8510 8mm SCSI tape drive. I've searched Google extensively - but have found no manual or even a switch settings guide.
It emulates an Exabyte EXB-8200/EXB-8500, a DEC TK50Z, an IBM 2.3 GB or the native TTI 8510 (from Google). It has twelve dip switches, three of which I've found to be the SCSI address - the others are a mystery.
Does anyone have a manual or guide to the switch settings for this tape drive?
Cheers,
Lyle

"Black holes are where God is dividing by zero"
I was just trawling through some of my file archives and found my old
email address when at University:
mwickens at vax2.luton.ac.uk - from 1993 to 1996
At the time I wasn't really into VAXen, but subsequently have wondered
about the VAX that handled my emails during that time. In the last year
a new Alpha system came online, and new email accounts were set up on
that box.
Anyone had interested email addresses in the past, or an email address
which represented a nostalgic time in their life.
The fluidity of email addresses interests me academically and
professionally - I work on systems which traditionally have involved
postal communication, but are moving over to email based communication.
This represents a challenge due to the fluidity of email addresses over
the course of the years.
Regards, Mark.
Last weekend I promised to enable rsync access to the archives
(and mirrors) here.
I've set up the following rsync (no password required) archive sets here:
ftp : Public rsync access to ftp://ftp.trailing-edge.com/ area
pdp-10-tape-images : public rsync access to the PDP-10 tape images,
i.e. http://pdp-10.trailing-edge.com/
bitsavers-mirror : public rsync access to my local bitsavers mirror,
i.e. http://bitsavers.trailing-edge.com/
Suggested rsync commands would be, for example:
mkdir ./pdp-10-tape-images
rsync -rlptu -v www.trailing-edge.com::pdp-10-tape-images ./pdp-10-tape-images
mkdir ./ftp.trailing-edge.com
rsync -rlptu -v www.trailing-edge.com::ftp ./ftp.trailing-edge.com
mkdir ./bitsavers-mirror
rsync -rlptu -v www.trailing-edge.com::bitsavers-mirror ./bitsavers-mirror
Realistically the pdp-10-tape-images and ftp sites don't change often,
butm my bitsavers mirror is kept up to date.
I like to think my outgoing bandwidth (20 Mbit) is pretty much infinite,
this looks like a good way to find out :-)
ftp racks up to 3.5 Gbytes. PDP-10 tapes racks up to 2.2 Gbytes. And
bitsavers-mirror racks up to 126 Gbytes.

A good source of Model M info is geekhack.org. There are some guys there with experience restoring/salvaging these keyboards.
They should also be able to tell you where you can find parts, etc.
I guess most of us on this list appreciate old and original copies of things. I have a small collection of old doc (although most of it is inaccessible to me at the moment) and record albums, photo albums etc. Things just seem to become unmanageable as the years go on and what was easy to find today can quickly disappear tomorrow.
I echo your sentiments and Chuck's. A huge thank you to Al and all the archivists who keep things available to others in this world of vanishing code, doc, etc.

I guess that's how I manage to only need a tiny (by modern standards)
hard drive. Manuals and books are on paper, photographs are silver images
and audio recordings, well not 8-tracks, please... 1/4" recording tape.
> probably won't ever be again.
I think it's a well-known fact that you never have enough disk space (or,
indeed, physical space for uour machines, test gear, tools, etc).
Joking aside, biutsavers is a tremendous resource from both the
historical and practical standpoint. It is much appreicated here. Long
may it continue!

The car manufacturers certainly do their best to prevent their
customers
from servicing their cars. Somebody I know had a Volvo V70 that just
refused to start one morning. Nothing obviously wrong, it just would
not
start. It had to be towed to a Volvo dealer. IIRC the problem turned
out
to be that two of the car's computers decided they didn't want to talk
to
each other. A software upgrade fixed the problem. It may even have been
the case that none of the computers had to do with engine management.
The owner of the car is very clueful about hardware, software and cars,
but it would still have been a major undertaking for him to even find
the
problem, let alone obtain the software upgrades.

Because they want you to either buy a new unit, or send the unit to one
of their own facilities to be repaired? In case of car manufacturers I
believe a significant portion of their profits comes from spare parts
and
service.
Do you have a mobile phone? Modern ones seem to be designed to break
down
slowly after about 18 months, they are full of custom parts, and the
people who repair them do their best to drive you mad. My work phone is
(hopefully) being repaired right now. It is 17 months old, the display
went permanently blank around August 6th, and the repair people have
most
likely not started working on it yet. I shall probably have to wait
another
2 weeks for it.

You guys and your extravagances!
I couldn't mirror it on one of my Sun boxes, the biggest drive I have is 73G...

So you'd need to expand, what, 20-30 times to fill an inexpensive
consumer-level hard drive? :)

Amazing, I didn't realize any were still running. Last time I saw PLATO was in the 1970s. The terminals were touch screens, they blew everyone's minds.
I'm convinced that my house was built over an Indian burial ground. Or
it was owned by someone heavily invested in everything but DEC...
I powered up my AlphaServer 1000A last night and it looks like it has
problems too. It powers up and the drives & fans spin up. The lcd
showed 'ec.' only once, every other time it is blank. Nothing out of
serial port 1 and the onboard VGA never initializes.
I tried setting the 'failsafe boot' jumper and I put a blank floppy in
the drive just to see if it would try to read the floppy and it didn't
even try :(
Any ideas at all?
So now it looks like both of my alphas are shot (the PWS500au never
initializes video, does anything with serial, and turns off all diag
lights) and my DECStation 5000/120 has a bad power supply.
On the plus side, all of my terminals still work and both of my vaxes
(MicroVAX 3100/90 and VAXStation 4000/90) boot to VMS without
problems.
It brings me to a question: are the alpha systems inherently fragile?
The dead DECStation is an obvious hardware issue due to (probably) a
leaked capacitor which is understandable due to its age, but the Alphas
are just hosed in a software kind of way.
