I now have over 40 recyclers across the country looking for items for collectors. Below is a list of what is being asked for. If you want to add to the request list, that is fine. The scrappers are asking for pictures. Remember that to them, this is just junk to be parted out; they are unfamiliar with the equipment. If at all possible, PLEASE send me a LINK to a site that has a clear picture, maybe some discussion about the machines in question. The stuff I look for is very general terms...ESCON and FICON are the names of the interconnects used to connect the machines to their disk arrays. ESCON is older (but still common) and FICON is current. The earlier one, called "Bus and Tag" or "Parallel Channel", is also something I can use, but they're very old and much less common. Models to look for are 3880, 3990, 3390 (much older), and "RVA". These will typically be biggish, very heavy cabinets containing drives and a controller. MicroVAX 3400, 3500, 3800 HSC50, HSC70 Any whole or parts of VAX 11/780, 11/785, 11/725 VAX 6000 RA9x, RA60, TS11 drives Any software and manuals for VAX machines If you don't know how to test, they request that you NOT even try to power the equipment on; they will buy it as-is. IBM PS/2 Model 70 A21 (specifically) IBM PS/2 Model 90 IBM RT PC 6150 IBM XT 370 Sun 386i SGI Prism Memorex 1270 Terminal Control Unit (used on IBM mainframes as an alternative to 270x TCUs) Memorex 620 (2311-11 equivalent), 630 (2311 equivalent), 660 (2314 equivalent) or 3660 (2314 equivalent) disk drives or the DEC OEM versions, the RP01, RP02 or RPR02 disk drive One terminal I have been looking for specifically for quite some time is the Ann Arbor Ambassador I'm always on the lookout for a Durango Systems "Poppy" PC It's unlikely because they were unpopular, but a specific Amiga I'm casually looking for is the CDTV - the one in the black "audio component" case. It's essentially an Amiga 500 with CD-ROM that looks like a VCR or stereo receiver. If you didn't spot the Commodore logo, you probably wouldn't notice it was a computer if you saw it in a stack of stuff. I am looking for scientific and industrial minicomputers from the 1960s and 1970s with "switches and blinkenlights" front panels. Digital Equipment Corporation (DEC) PDP-4, PDP-7, PDP-9 PDP-8 and older PDP-11 models with the blinkelights Data General Nova, Honeywell, Modcomp, and others as well. I'm specifically looking for these machines from Computer Control Company (3C), likely labeled Honeywell (after an acquisition): DDP-24, DDP-124, DDP-224, DDP-416, DDP-516, H316. These are large machines in 6-ft racks or 4-ft cabinets. Also Datacraft 6024 and early Harris machines. Probably a longshot, but I'm still on the hunt for JC80 series equipment that was made by Johnson Controls. The JC80 was a building automation "computer" that was made in the 70s/80s. I also wouldn't turn away other old Johnson Controls stuff from the 1980s or 1990s such as JC85, DSC, old Metasys, etc. My father once serviced these systems so I'm very familiar with them. They are not the kind of thing that anyone who collects old computers would likely want, so I suspect that 99.9% of them have been scrapped long ago. I'd be willing to pay scrap value plus 10%, which probably wouldn't be all that much anyway since these things are big heavy steel boxes and racks with a lot of empty space inside. Because this sort of stuff is so specialized, I wouldn't expect anyone to test it, and in fact it would probably be safer not to try to test it since it would need repairs and maintenance before it would even be safe to power up. For me, non-PC keyboards are important - pre-ADB "Classic Mac" keyboards or Amiga, especially Amiga 1000 keyboards in particular. I'm big into Commodore, so anything pre-C-64 is also interesting (PETs, VIC-20s, disk drives, some printers). Old external disk drives (single-sided Mac and any Amiga) are also useful and interesting. a complete Royal AlphaTronic PC system - with monitor & at least one of the floppy drives. This is what it looks like: http://vintagecpu.files.wordpress.com/2011/10/royalta.jpg IBM 3174 desktop controllers Any VAX mainframe computers, or any old DEC 6' cabinets that are populated.

PERQemu Source Release

by derschjo＠gmail.com

Just in case anyone's interested, I've finally gotten around to cleaning up the PERQemu source to the point where Idon't feel too ashamed to show it to others. (It's still a bit messy.) I meant to do this years ago but kept putting it off. I'm releasing it under the GPLv3 in the hopes that maybe some other PERQ fanatic can finish what I started (or at least use it as the basis for a different implementation). These days I have too many other projects occupying my time to spend much time with it, and I kind of got burned out on it a few years back. http://yahozna.dyndns.org/projects/PERQemu/source/PERQemu-source.zip (And you can read more about the project at http://yahozna.dyndns.org/projects/PERQemu/index.html) And a big thanks goes out to our own Tony Duell for his extremely patient help with this project; the answers he provided to my questions when I started on this project back in 2006 could fill a small book :). And thanks to Al & Bitsavers for the scanned documentation and archived software. Without these this project never would have gotten started. Thanks, Josh

Old UNIX Systems

I used to run Sun gear all the time at home. I just don't power it up anymore, so the strict answer to your question is "keeping the shelves from being empty". At one time, old Sun gear was a great gateway to learning "real" Unix and a foot in the door for a "real" job. It's been far, far less true for coming up on 10 years. And then, around 4 years ago, give or take, if the job postings said "Solaris experience required", it was Solaris 10 or nothing, something you can't do with SPARC hardware from the 1980s. I've turned down more free Sun hardware in the past 2 years than I've kept. It's still elegant, and it still runs DNS and web servers, and plenty of other things, but I personally don't care to spend that much on electricity for those sorts of services at the bandwidths I require - an old laptop running Linux can do everything I "need" at home in the way of services and suck up 90W or less. I also have VAXen that I only turn on for special occasions - too hungry to leave powered on all the time like we used to do back in the day. Of course, in the winter, it's "electric heat", so no harm there, but it's summer up here now, so most of that stuff stays off except for a few hours here and there. -ethan

Can we point you to web sites with pix? For DEC gear, you might look at http://research.microsoft.com/en-us/um/people/gbell/Digital/timeline/tmlnho…. There's likely a taker for many of what is pictured. People have mentioned VAXen and PDPs. If something is found pictured in the 12-bit section there will certainly be *very* interested takers, and if they find objects in the 18- or 36-bit sections, they may want to post guards. KJ

Pre-unicode Swedish character set?

List: I'm working with some old media that has Swedish text on it. (8" SS FM disks with 4 sectors of 1024 bytes per track--no OS or file structure on it).

My Epson TF-20 booting (but not on YouTube)

This list gets long if so) a license. Things run slower, by a factor of about 100, but they still generally run. Because: I own machine and Mathematica license, so am pretty sure no upgrade/license server issue is going to stop me calculating. As long as my laptop is on the 'net somewhere, I can VPN to the NeXT and get numbers back over the terminal interface (or retrieve plots via sftp). Newer hardware for backup Mathematica is not hard, new license is expensive. 1b) as above, running distributed.net.

Because: machine is always on (see above), might as well put those CPU cycles to use. No power-save mode like on my laptops. 2) Powerbook 3400, drives an HP flat-bed scanner (which is SCSI interface) and plays games. Because: Scanner quality rocks, don't want to buy new scanner, no SCSI interface on any new machine I own (and not sure about drivers if there were). Don't want to buy new scanner; new scanner linearity probably is not as good anyway. 3) (?) LaserJet 4M+, only working printer at home. Because: per-page cost is very low, print quality is fine for everything we need at home. House wired for ethernet, so no problem with connectivity; even laptops speak 802.11 to DSL hub which puts packets on ethernet to the printer. Printer is paid for and even a "cheap" new printer will chew through toner faster than I like. 4) iMac G3, secondary web-surfing machine at home If wife or kids are on the iMac flat-screen, I can still do my banking/book club/check weather radar on TenFourFox (THANK YOU, Cameron! 10-4-Fox-ROX!) http://www.floodgap.com/software/tenfourfox/ 5...n) Education/Nostalgia machines *Finally* beginning to understand machine language, thanks to the TRS-80 Color Computer's 6809.

(Yep, I know I'm talking absolute nonsense physically, but you get what I mean...) I have both a E3000 and a E4000, as well as a couple of U450s. These are my largest systems right now, with a HP 9000 K100 (PA-RISC) as a close follower and a HP LH6000 NetServer (dual x86) coming next. For the record, none of these is in active duty with me right now. The E3000 (equipped with the "Creator3D" UPA-capable I/O board no less!) blew the switcher transistor in its PPS1 (peripheral power supply) with a loud bang when I last tried to power it up, burned out two inrush limiter resistors and tripped the circuit breaker. The supply is optional, so I think I could still run the system (with not too many SCA disks in it) right now. I remember doing a test install of Solaris on my SparcSERVER 1000 (two processor boards w/ one processor each) in my upstairs bedroom at home and being already quite impressed by the amount of heat that put out. The K100 has two impressive-looking radial fans in the bottom and I'm curious for their noise alone when I'll be powering up that system! So long, Arno

Not too noisy, and a very convenient form factor. Particularly with multiple heads, older SPARCs could still be useful as X terminals (the Solaris X server just works, whereas configuring X on random PC hardware can be frustrating even in these modern times). Also, if you're writing code where portability is important, it doesn't hurt to have on hand machines with "weird" (relative to x86) CPU architectures for testing. (of course, there's always emulators) But to be honest, I keep mine primarily out of sentimental value, and not for a practical purpose. I still have this crazy notion of someday acquiring an Ultra Enterprise 3x00 or 4x00 to run at home for real work, though.

Supporting System Collections -- Media, File Systems, Booting

by pbirkel＠gmail.com

Have any of you with "machine farm collections" set up any sort of file-system-server to manage disk images, "serve" disk images, or direct-boot across your collections? For example, see this moribund thread: http://www.pdp11.co.uk/blog/2008/11/17/building-reliably-modern-storage/ ----- Building reliable modern storage For many years I?ve been pondering the problem of how to provide a reliable long term storage solution for my PDP-11 and PDP-8 machines. Whilst I have plenty of period drives which are still operational it is apparent that in the long term it is unlikely to be possible to keep them all running. It also a sad fact that many more CPUs are being saved from the scrapheap than drives leading to a lot of collectors having a CPU unit but no storage to boot them from. I?m therefore kicking off a pet project to build a versatile solution using modern hardware to provide a long term storage solution for our machines. The key objectives of this project will be as follows: - Provide a reliable solution that as far as possible is not tied to any technology that is likely to become obsolete in the next 10 years - Ease of installation and operation. - Provide adequate storage capacity for all of the common PDP-11 operating systems - Make as much use as possible of pre-existing efforts to crack this problem My initial plan is to develop this solution in two phases: 1. Would involve a server running SIMH, a TU58 emulator, vtserver and an RX01/02 emulator. The server would operate under Linux operating system (Centos4) and would have a web based interface for managing the various components. Installation would be via a yum based repository allowing users to install and update the setup on their system from a simple set of commands. 2. Much more ambitious, but where I think we should ultimately reach will be to develop custom Unibus/Qbus/Omnibus controller cards for interfacing directly to the bus. This will allow us to provide a solution with a good level of performance without any requirements for pre-existing controllers (such as RX11s). -----

Still looking for a home - RA81 parts

by aperry＠snowmoose.com

I (still) have parts from a DEC RA81 HDD that I took apart years ago that I would like to get rid of. I posted them here a while ago, but figured that I would try again since I am trying to clear out space in the garage for a car project. I am primarily concerned with finding a home for the two larger parts. 1. The HDD minus the HDA. It is 28" x 18" x 10" and is fairly heavy. It has all of the boards. It is everything except the platters and heads. I imagine that, if you powered it up and hooked a tty to the serial port, you run diagnostics on it. Though, without a HDA, not many tests would pass. 2. An empty HDA. This is the aluminum housing that the platters and head assemblies once occupied. Located on Bainbridge Island, across from Seattle. Probably too big/heavy to ship. alan

Any Top Tips for ddrescue?

by steve＠stephenmerrony.co.uk

As I haven't been able to source the microcode for my MV/2500 I am attempting to rescue bits/bytes/words from it's 330MB system disk. Naive use of ddrescue has yielded about 80MB of the disk - does anyone have any suggestions for improving that ratio? Also, are there any tools out there for examining partial disk images in strange formats? :-/ Steve -- /Stephen Merrony http://stephen.homedns.org/dg/ /

Power supply for HP9845B/C option 200

by dfnr2＠yahoo.com

Hi all, I'm looking for a power supply for an HP9845C option 200. I was fortunate to acquire an HP9845C.? I am in the process of moving, so I haven't had a chance to examine it fully.? I did open up the base, and it has the option 200 CPU set.? It looks pretty clean inside, although the power supply is missing. I do have a couple of working HP9845B's, but these use the hybrid processor, and my understanding is that the option 200 machines used a beefier supply. Does anyone know if the regular 9845B supply will work in an option 200 machine? The schematics are pretty complicated.? I'm wondering if the power supply has any special qualities that would prevent my putting together a switcher to supply the needed voltages, via an adapter. If I can't find a supply, I may try to "downgrade" the unit to a hybrid processor, by swapping out the CPU from a 9845B, with a replacement ROM board loaded with the 9845C image; or, swap the monitor and keyboard over to a 9845B, and add the 9845C ROM image.? Can I expect either or both of those options would work? Right now, we are in the middle of moving, and I don't expect to have a lab for a few more weeks, but when I do, I would love to try to get this machine up and running. Many thanks, Dave

IBM 082 Card Sorter has found a new home

by j＠ckrubin.us

The card sorter will be heading off to Binghamton, NY where it will become part of an IBM 1440 restoration project at the Center for Technology and Innovation. Chances are pretty good that the sorter was actually built in Endicott, NY so it will be returning home after a 50+ year absence. Thanks to all who made an effort to keep this relic from the crusher!

Jnet for VMS

by saquinn624＠aol.com

>I wonder that since Quest is now owned by Dell, would Dell be more open to this? > >Thanks, >Brad Arnold The problem (from the point of view of the owner) is that any sort of release requires a time commitment to ensure that they're not opening themselves up to claims for royalties from licensors, creating infrastructure, vetting licensing terms, setting up download servers, etc. - and the net return is about zero, as the software isn't sold anymore. Nice in theory, but hard to justify for the company on business terms. MultiNet, TCPware and OVMS are still sold, so there's a publicity motive - that and originally hobbyist overhead was taken over by the openvmshobbyist/Montegar group.

Power Supply restoration for Xerox Star 8010 and PILOT OS needed

by nick.allen＠comcast.net

Hey everyone, I recently acquired a Xerox Star 8010, I now have panels for it (Thanks Jason Timmons) and am now working on the power supply. It is missing the transformer, does anyone have documentation on the power supply? I know it outputs 5v/12v and therefore I am looking at a 8v/16v transformer. Any recommendations on AMPS? I can find a 20A/30A transformer or a 80A/120A transformer, any suggestions? Also, anyone have a digital version of PILOT (the OS for the Xerox Star) or know where I can get a copy? Thanks! Nick

Q-bus chips

A while ago someone was looking for various Q-bus chips. I don't remember who or what the chips were. If there are usable chips on the DEC M8044, I have 25+ of them that the chips could be removed. If anyone one is interested, please contact me off list with an offer. I can knock off a few bucks per board if you don't want the fingers. shipping is from Illinois, 61853. I'm still clearing out items, trying to make pathways. Thanks, Paul

LA180 / DecWriter I

by quapla＠xs4all.nl

Hi, After being kept in a corner, I unearthed my LA180 aka DecWriter I. After powering it up, no magic smore, but some humming from the fan. The selftest went ok, but the ribben needs replacement, the characters were faint. Now, I want to hook it up, so I opened the backpanel to locate the serial line, only to find out is is not having the converter board which is an LAXX-NY for EIA signals according to the user guide. So, is there someone having this board and is willing to sell it? Thanks, Ed -- Dit is een HTML vrije email / This is an HTML free email. Zeg NEE tegen de 'slimme' meter.

We currently buy delay lines from Rhombus. They have limited stock of many items for prototyping and repairs. Digi-Key has a wide range of pulse transformers from about 5 manufacturers. If the transformers are 1:1 winding ratio, there should be a huge range of parts available, and the exact inductance may not be very important. Jon

Sourcing DIP Transformer replacements

by derschjo＠gmail.com

I've started looking at what it's going to take to get the memory in the Imlac running again. There are two core assemblies in this machineand they're both in pretty bad shape as they were exposed to moisture for a long enough period that they accumulated quite a bitof corrosion on the control logic. (The cores themselves seem to be OK). I went over the better of the two assembliesand cleaned the legs of every socketed IC. In the course of doing so I found maybe 10 chips with legs that were falling off. I took alook at a random sampling of chips from the worse of the two assemblies and every single one of them has legs that are corroded through. So I'm going to be replacing a lot of chipsif I want to get these running again. Most of these are 7400-series logicand aren't hard to find. However, there a set of components that I'm not too familiar withand I'm not having much luck finding replacements. Now that I have the schematic I at least know what they are(had no luck looking them up based on the labels on the chips), they're described as "Transformer, 60uH", "Transformer, 6uH" and "Transformer, Square Loop" and have part numbers of 517A0024, 517A0023, and 517A0021. The chips themselves that are in my machine are labeled as follows (for the 60uH variant): 14201 NPIPA-2581 <date code> These are in 16-pin DIP packages. I'm going to need to replace quite a few of them. Any ideas of a modern replacement? (Any idea where to source NOS or used ones?) I can provide pictures if that'll help. Thanks, Josh

Perhaps another way to try to understand it is like this: when Hatfield bought the computer from Apple, his *intent* was likely merely to purchase the A1 and use it; his purchase was likely innocent; he likely had no idea that in the future, it would be worth 60x more. In other words, his 60x gain was a fluke... a bit of luck.. not something he *knew* about in the back of his mind when he bought the A1 from Apple. Now the next guy. Here's the key difference: he bought the A1 for $40k full well knowing he could turn around and sell it for at least $300k. His 12x gain was no fluke, no luck, but something he *did know* about when he bought the A1 from Hatfield. What McGuire is saying, is that a moral person neither ellicits gain through deception NOR that other perverse way of lying: not telling the whole truth.

Bad Bernoulli Box media - ideas?

by mbbrutman-cctalk＠brutman.com

I just ran through all of my 5" 20MB Bernoulli Box cartridges and a lot of them would not format using the Iomega tools. The media itself looks fine, but it might be worn out or magnetically compromised. This media uses servo information that I don't think can be written by the drive. So bulk erasing to try to clear up errors is out of the question. I tried it just for grins and what was a marginal disk now never comes ready. Aside from making sure the drive and heads are clean, is there anything else to be done with these? (In the event that they are dead, I'm looking for ideas for an art project using them. ;-) ) Mike

A friend of mine is being forced to vacate his building at the end of the month. He has a nice Model 83 Card Sorter that has been well stored but unused for years. It must be removed before the end of the month. This is BIG - approximately 5 feet long, 4 feet high, 500+ pounds. If you want it and can come and get it (lift gate truck a necessity), please contact me _directly_ ASAP. It will be junked if not taken this week. Thanks, Jack

Looking for Arraid AEM-1 SMD drive emulator operation info/commands

I need SMD drives on my machines because the legacy OSes I run don't support MSCP, and I need large capacity (relative to RK/RL) disk. Now that I've acquired some of these AEM-1 units to replace my ailing SMD drives on my PDP-11 systems, I'm confident I'll keep my machines and OSes running for quite some time. I've got two units running now, with only a day's worth of effort primarily due to the unclear documentation, and both are working great with Emulex SC31 UNIBUS controllers (and also with UD33s). If anyone is looking to keep an SMD disk-based system running and concerned about failing media, I highly recommend looking into these used Arraid devices.? The prices have come way down compared to new, and they've been showing up on ebay regularly. Just thought I'd share my success. -scott
