Hi My employer is moving house and need to clear out some old stuff. We have ported to many, many Unix systems over the years and have kept some of the machines. Available is: 1x IBM RS/6000 big and beige 1x Bull DPX/2 1x Concurrent Computer Corporation in rack 1x Sperry unix machine 1x NCR (same as above, other label) Possibly 1 VAX 4000 and possibly one Alphaserver 2000. Pickup only. We will remove hard drives since they contain source code. In a few weeks, this will be gone. A few pictures here: http://www.update.uu.se/~pontus/slask/jobb_vind/ Items are in Uppsala, Sweden. /P

Still wanted: Symbolics Gear

by lists＠loomcom.com

Hi folks, This is as always a tremendous long shot, but I figured I would put it out there anyway. I am still eagerly looking for any and all Symbolics systems. I know very well how rare these things are, and how much money they are worth. If you have any systems you would be willing to let go of, let's talk. I'm happy to entertain trades if that's something you're interested in, but I'm also happy just to pay fair market prices. For reference, I am located near Seattle, WA. Best Wishes, -Seth P.S.: I also know how difficult they are to care for and keep running! I'm all too familiar with dying ESDI drives and bad power supplies.

OT: Come watch me install Linux on the IBM z890 Mainframe!

by connork＠connorsdomain.com

Come one come all! Its the day of reckoning. I finally have some storage on loan from a company called Funsoft! Hopefully by the end of the night I will have Linux installed and a portal to the internet to which people can connect and play on it! http://www.twitch.tv/conmega -Connor Krukosky

Circuit Design Aids / Unix Circuit Design System

by mark.kahrs＠gmail.com

In the original Unix BSTJ of 1978 Sandy Fraser described a system he called "Circuit Design Aids". Schematic capture was done on a 4014 and conversion went all the way to wire wrap. CDA was rehabbed and rewritten by many people over the years. It became known as the Unix Circuit Design System (UCDS) and it was available from Bell Labs under a separate license as I recall. UCDS was used to design many projects including the 5620, Belle and others. When Plan9 arrived, UCDS was converted to Plan9 (not too hard...) and renamed back to CDA. The code was released in the first Plan9 CDROM. So. It occurred to me that I could back port it to Linux. I did so with help from H. Trickey and the Plan9 compatibility library. I put all of this code on https://github.com/kahrs/cda. The interested and curious can find it there. I make no promises about full functionality, however, it is available for those who want to tinker.

BA23 fan noise

by Mark＠Misty.com

Hi, I've been messing around with my PDP11/83 and a Microvax, both in BA23 boxes here. These fans make too much noise for my home office area, and I cannot possibly need the original airflow. Even with the internal jumper set for 10V to power the 12V rated fan motor, these are still noisy. It's not even just the noise of the air moving, but largely a whine from the fan motors. One box is worse than the other with the wine. I've unplugged the front fan, since instead of spinning drives I have solid state CF cards and SCSI converters -- no heat in the front of the box at all. I have some 24V fans in my junk box that fit and make almost no sound at 12V, but at half voltage might not move enough air to keep the power supply, CPU, memory, SCSI, and ethernet boards happy. My guess is so long as there is some air movement over the boards, the biggest issue of concern is cooling the power supply. Does anyone have any suggestions for figuring out how much airflow I actually need, and achieving it with either stock fans at further reduced voltage, or some kind of replacements? I don't need an accurate solution, or something with complicated compensation for varying temperature, just something quieter, moving less air, but still enough air. Mark -- Mark G.

Vintage Computer Collectors - TV Special Inquiry (fwd)

by sellam＠vintagetech.com

Does anyone want to have their children exploited for profit and entertainment? "I'm currently Producing a show for TLC that features children who have a passion for collecting. I was wondering if you know any kids who have a sizable collection of vintage computers? If you can think of anyone who would be interested in appearing on our show, I would greatly appreciate it if you could connect me with their parents to discuss the show further." If anyone is interested e-mail me privately and I'll give you all the contact details for this producer. -- Sellam Abraham VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap.

PDP-11/03, LSI-11 KEV11-C CIS option

by spacewar＠gmail.com

Does anyone have a PDP-11/03 or LSI-11 with the KEV11-C CIS (Commercial Instruction Set) option? It may have also been known as DIS (Dibol Instruction Set). It apparently consists of two microcode ROM chips (MICROMs), 23-004B5 and 23-005B5. Last month I posted here about building a circuit to dump the contents of MICROMs: https://www.flickr.com/photos/22368471 at N04/albums/72157662054690240 I've dumped the base LSI-11 instruction set chips and the EIS/FIS chip. I've partially disassembled the former: https://github.com/brouhaha/lsi11uc and verified that the latter matches the EIS/FIS microcode source code provided with the KUV11 writable control store support software. I'd like to dump the CIS microcode ROMs as well. The resulting dump would be usable by anyone with a KUV11. I'm contemplating developing a MICROM replacement board, which would be useful for those without a KUV11. I've made more progress with the WD9000 Pascal Microengine microcode than the LSI-11 microcode because someone provided a photomicrograph of the CP2161 control chip and I was able to dump the PLAs. I should be getting a photomicrograph of the CP1621 control chip of the LSI-11 soon, and will be able to do the same for it.

Looking for Solaris 8 patches

by nf6x＠nf6x.net

I'm looking for a bunch of OS patches necessary to get Firefox 2 running under Solaris 8 on my Sun Ultra 60. The patch mirror I used previously appears to have dumped the Sun patches in 2014, and the only up to date references I've seen to Sun patches now appear to be locked behind an Oracle cu$tomer $upport login. Perhaps Oracle bludgeoned any open mirrors to death with stacks of C&D letters? Are there any open mirrors of old Solaris patches lurking out there? Or maybe somebody has a private stash of patches? The ones I need are these ones (or later versions): 108434-17 108435-17 108652-79 108773-18 109704-03 111721-04 114542-01 I have older versions of all but the last one already, which I fetched a few years ago. But the older versions won't allow Firefox 2 (which is the latest browser I've found for Solaris 8 so far) to run. I have Netscape 4.76 on the machine, which is too old to deal well with the modern web. I'm not sure how much better Firefox 2 will be, but I'd like to find out! -- Mark J.
