Thanks Jon, I'll save his name and try to look him up. I'm slowly working on a

I'd love to have a copy of it. I'm slowly working on a G-15 emulator, and it 
would be interesting to see one for Intercom 1000 as well.

I might be interested in the Ultrium LTO fibre-channel drives and tapes.

I'm getting ready to move so can't do anything soon.  However if nobody 
else raises their hand in what you consider to be a reasonable amount of 
time, I hope to be in a better position and would happily pay shipping.



I have two Fujifilm 200/400 GB Ultrium 2 LTO tapes.

I have a 5.25" floppy drive.

Any of these are yours for the price of shipping; local pickup is OK
too.

Hi, Mike,

I forwarded the original post to Keith Perez, the engineer who did the
restoration at LCM+L, when it arrived in my mailbox.  I haven't heard from him
to know if he contacted the poster.

Keith had the machine working very nicely.  In addition to the actual
restoration, he created a device which fit into the tube (Brit. valve) holders
to report the health of the tubes (which are not visible when the computer is
assembled) and report via edge-visible LEDs; these were easily 3D-printed and
cost effective.

We actually had two G-15s; Keith worked on getting the second into running
condition as well.

I wrote an emulator for Intercom 1000. Happy to send it to anybody who
wants it.

The folks at the Living Computer Museum + Labs in Seattle were working on a 
restoration of one of these, or another, similar Bendix machine.  They remain 
closed (who knows if they will ever reopen), but there might be a way to find 
some of the people who were doing the work.

There's a Rob Kolstad in Colorado Springs who actually used a G-15 many ages 
ago, and has created a simulator for the G-15. He has some info on internals as 
he was hoping to eventually find one to restore.  I think he has a bunch of

[cctalk] Fwd: Bendix G-15 Documentation

Bendix G-15 DocumentationDear Fellow G-15 Enthusiast,
I'm Rob Kolstad, and I am sending you this little informational blurb
because I think you are interested in Bendix G-15 projects (sometimes
because I have seen someone messaged you about such things in the last
two decades). Feel free to send me an 'unsub' note to never hear again
about such things.
This note announces the beta test of the first set of the documentation
collection:
https://rbk.delosent.com/g15doc.html
The collection includes 161 source documents (some duplicates)
comprising some 10,566 pages (including blanks). I have broken some of
the source documents into their constituent sub-documents (e.g., the
Technical Application Memos) for easy access, yielding 1,414 documents
in total.
The collection is by no means complete (coming soon: good large-format
schematics and perhaps a search bar), but it's a good start. I'll try
to scan the rest before the year is out.
The fine folks at the System Source Computer Museum in Baltimore have
gained, at least for now, several Bendix G-15's (and peripherals) along
with more than two dozen boxes of Bendix documentation mingled with
documentation of a large highway engineering firm's projects. The
collection also has hundreds of paper tapes in fabulous condition.
I scanned a fraction of these documents back in June and combined them
with my personal collection (thanks to Bob Sander-Cederlof in Texas)
and the documents from bitsavers.org and the Computer History Museum
(among others).
This documentation section forms one of the main parts of the soon-to-
be-released (2022) bendixg15.com website for all things G-15, including
software, hardware/restorations, emulators, news, photos, and notes.
Please feel free to check out the documents. I'll let you know in a few
months when the general web-site is available. Comments, questions, and
suggestions are always welcome.

GCC does this in two steps.  One is that it's marked as obsolete but can still 
be built, you just get a warning.  The second is that the bits are actually 
removed.  If you want to run something old, it's probably still good until that 
final removal.  But given the lack of maintenance that triggers removal, it is 
certainly possible that there are some "bit rot" bugs before that point, 
possibly even before the first warning stage.
