Thanks Wayne, I'll do some more digging. Anything helps.
[cctalk] Re: Bendix G-15 Restoration
Thanks Jon, I'll save his name and try to look him up. I'm slowly working on a simulator as well, but the paper tapes are real treasures!
[cctalk] Re: Bendix G-15 Restoration
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.

Thanks Rich! Keith did contact me, and I expect he will be of great help along the way. Steve

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. Rich

[cctalk] Re: Bendix G-15 Restoration
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. -mike -Original Message- From: Jon Elson via cctalk Sent: Thursday, October 6, 2022 11:40 AM To: Jon Elson via cctalk Cc: Jon Elson Subject: [cctalk] Re: Bendix G-15 Restoration On 10/5/22 22:00, Jon Elson via cctalk wrote: > On 10/5/22 16:14, Stephen Buck via cctalk wrote: >> Hi All, >> I wanted to let the group know about a Bendix G-15 Restoration >> project I just launched: >> https://headspinlabs.wordpress.com/bendix-g-15-restoration/ >> It's a pretty intimidating restoration (do no harm and all), so I'm >> reaching out to related sources, such as this group, for any >> suggestions or interest. > > WOW!

[cctalk] Fwd: Bendix G-15 Documentation
Forwarded Message From: rob.kols...@gmail.com To: van.sny...@sbcglobal.net Subject: Bendix G-15 Documentation Date: Mon, 3 Oct 2022 19:09:34 -0600 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. paul
