Folks, In going through my archives/basement I found three HP 12747H 64K Memory boards. I have no idea if they work or not or if anyone is interested in them. I received them around 12 years ago when a former customer was decommissioning an HP/3000 and they were giving out the internals as mementos to the staff. Shipping would be from 46219. -- -Jon Jonathan Katz, Indianapolis, IN.

Unobtainium obtained!

by ggs＠shiresoft.com

I just thought that I'd let folks know that I scored a bit (ok quite a bit) of unobtainium in the form of Unibus receivers and transceivers. It wasn't cheap but I just received 100 DS8640Ns (Unibus receivers) and 500 DS8641Ns (Unibus transceivers)! I would have gotten some Unibus drivers too if they were available. I think I'm now set (including the stock that I had previously) for the projects that I need them for (now I just need the time to actually work on those projects). Before anyone asks, these were obtained through a supplier on the secondary chip market. They only deal with commercial entities (one of the reasons I have one) and aren't interested in "small" quantities. It's hard to get them interested in an order under $1000 (and my total order for the above parts was well over that). TTFN - Guy

Nuclear Data ND-812 info...

by jim.mainock＠billjacobs.com

Josh, I just seen your post on the BR2412 and thought I might be able to shed some light on the ND812 Computer. I worked for Nuclear Data when they designed and started production of this computer. Nuclear Data prurchased DEC PDP8 and PDP11 computers to to process data from their nuclear instrumentation products and decided to build a system simular to the PDP but with an enhanced instruction set and floating page. The software developers created a point of sale demo and tried to sell it to McDonalds Corp. They laughed and said no thanks. The sales people then show the system to Jewel Foods and they decided to partner with Nuclear Data. Nuclear Data was loosing money and redesigned the system with the new spec 16 technology how ever the spec 16 was delayed for a year and Nuclear Data was forced into selling the point of sale division of the company to Bunker Ramo that is where the BR2412 model designation came from. I personaly trained most of the new technicians we hired on troubleshooting the BR2412. My last job at Bunker Ramo was running the test engineering department and then I went back to work another year after the sale at Nuclear Data. Nuclear Data was one of the best companies I have worked for. If I can aswer any questions you might have on either Nuclear Data or Bunker Ramo feel free to contact me via email. Thanks, Jim Mainock Jim.mainock at gmail.com

I'd also like to offer my thanks to those involved. It's good to see a happy ending to this saga. Just an FYI, it looks like I will have to download the file at home, because when I try at work, the anti-virus software in our SonicWall firewall appliance blocks the download, saying it detects the "Dos.Cursor" trojan.

by emu＠e-bbes.com

Hi all, never noticed that before, but my version chokes on disk > 2GByte. (OS works, but "SHOW DEV" gets confused) So, what is the newest version of the PROMs? What I have here, is: KA49-A V1.1-06B-V4.2 Cheers

Old Unibus VAXen (was Re: eBay VAX-11/780 has a few minutes left...)

by tshoppa＠wmata.com

Ethan writes: > The 11/730 wasn't so bad if you used it like a single-user workstation. Indeed, if you look at its internals, it has a lot in common with the never-marketed PDP-10 Minnow (AMD2901 bitslice, RL02/R80 support board) which was thought of as a desk-side or desk-top PDP-10. Tim.

Old Unibus VAXen (was Re: eBay VAX-11/780 has a few, minutes left...)

by elson＠pico-systems.com

It's been more than 25 years, so my recollection may be hazy, but I think we had 208V 3-phase. I don't recall if it was delta or wye configured, but I tend to think it was the former. CPU from one phase, disk and tape drives from the other and our two big CDC line printers from the third. But as I said, it's been over 25 years since the electricians installed the stuff. We just went by what they recommended. Chuck Yes, our 780 was 208V 3Phase, and I'm PRETTY sure it was 5-wire, so it had a neutral and a ground pin. I think some of the outlets are still in the wall at work, so I'll check the twist-lock to see. I think the power supplies could run off 240 V as well, but possibly the whole machine was slightly different for that option. I know our big data center with IBM 370s was all 208 V also. The multiple H7800 (I think) power supplies each ran off a single phase bridged between two hots, but they were distributed around the phases. The LSI-11 and maybe a few other things ran off 120 V, and I think there was a scope/etc. 120 V outlet there, too. The big cooling blowers were each across two different phases. Some of the larger disk drives had 3-phase motors, and the high-end tape drives (TU-76, TU-77) had 3-phase power supplies and vacuum blower motors. I think the Vax 11/750 was single-phase 220 V, and the 730 was 120 V. Jon

I had no idea these are still in demand; I will have to get all mine tested and posted on the website. A few are there, but not too many.
