I picked these up as part of an estate liquidation, but I don't have a
Unibus setup to run them off, and they are large and taking up space. They
now need to be gone. The condition is unknown but they are intact.
If you know what one is, you probably know how to hook it up and use it. If
you don't, they are NOT VAXen -- they're more like overgrown graphics
terminals that connect over Unibus. They are not like other VAXstations.
Take as many as you like (greater Los Angeles area). However, units that
are not spoken for, or haven't made other arrangements regarding, will go
to the recycler this weekend. E-mail me offlist if you are interested.

Hello everyone,
It's been about a year since I last asked around, so I figure it's
time for me to put out another call for help.
My AT&T 3B2 emulator sits unfinished due to lack of internals
documentation. If you or anyone you know might have access to
internals documents -- schematics, timing diagrams, etc. -- please let
me know.
These docs are very hard to find, and may never have been released by
AT&T. Maybe you know a former AT&T engineer who managed to squirrel
some away?
I have many resources already, so I'm NOT looking for user manuals,
SVR3 source code, or the IO Bus specification. These are pretty
easily available online, and they've given me their all.
Many thanks in advance,
-Seth

Dave,
I am interested. I have an HP 2647 with two restored tape drives, and have
been looking for this exact tape set. I have some "new" Athana tapes. Step
1 would be to copy them to a new Athana master tape. Then step to could be
to make copies available to the group. Step 3 would be to transfer them to
an archive format, but in essence it's already been done by the hpmuseum
(in 5.25" 2647 disc format, LIF I presume?). But I don't have that rare disc
unit and interface card to connect it to the 2647 (if I had, I could
indeed recreate the tapes). That said, I first need to work on step 0, which is
lots of practicing recovering DC100 tapes reliably: baking them, changing
the belt, cleaning the guides... Fortunately I have lots of DC100 tapes that
I need to recover before touching yours. It might take me a couple month
to get there. Contact me off list if you want.

Hello,
I have a couple of HP 2647A tapes:? BASCI/AUTOPLOT47 and DEMO.?? They look to be in good condition.? I have had them in a climate controlled lab since acquiring them as part of a sizeable lot of HP tapes last year.
I am curious if there are any known good copies of these tapes out there.?? Are these the same as (i.e., can be created from) the floppy images available on hpmuseum.net?
If these are not already archived, I would be interested in preserving them.? I realize that reading tapes this old may be a "one-shot only" process, and I don't have the expertise or equipment to be able to archive these tapes.
Is there anyone on this list with the interest and ability to archive these tapes and make the images available to the community in a useful format?
Thanks,
Dave

I've been looking for LED replacements, but I haven't seen them; I'd have
thought that that would be a pretty popular item, but I haven't seen them in
any local stores. Are they only available as an online option?

Definitely - ballasts are such a pain. Actually, let me be more accurate: the
ballasts in 4' (40W) lights (where they put the two bulbs in series) are a
pain.
The new ballasts for the 8' lights (a couple of decades back, in the US,
regulations mandated a change) are actually a delight; you have to re-wire old
fixtures a bit to install them (since the new ones no longer run the lights in
series), but the upside is that 8' bulbs now either work - or don't.
This is distinctly unlike the 4' ones, where bulb X will work when paired with
bulb Y, but not when paired with bulb Z. (Because 40W bulbs are wired in
series pairs, and as they age, their characteristics change.)
I don't suppose there are ballasts for 40W bulbs that _don't_ wire them in
series?

Does anyone have (a scan of) a manual that covers programming the MV-era
MTB tape controller?
I have a 1980 "Peripherals" manual (014-000632-01) from the
"Programmer's Reference Series" which covers the MTA type, but it seems
that the MTB behaves a bit differently and I am missing some information
for my current project.
Thanks,
Steve
