Current Do Not Buy/Bid list (eBay) - STOLEN VCF Archives Items

by sellam＠vintagetech.com

David, To answer your question: the truth of the matter is no. My affidavit contains their soul response: an illegible (legally invalid) notice to sell my property that came only after I noticed them of their deficiency in process and did not meet any of the statutory requirements and was undated (hence, illegible). As it was merely intended to cover their asses, it was not really a serious notice, as even when I exercised my right to reclaim my stuff per their notice they still refused. I will post that particular exhibit with the rest of the exhibits as soon as I can get them scanned. The landlords did finally respond to the complaint, which I received in the mail today. I'll scan and post that as well, for what it's worth. It's filled with stuff attorneys get paid to write. -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.

HP terminals

by sales＠elecplus.com

There are 5 HP 700/96 terminals with keyboards. The keyboards are complete. 1 of the terminals has significant screen burn in white mode, but not in black mode. 4 terminals come up crisp and bright white, no screen burn, no scratched glass. Cases are very dirty right now, but I can clean them. Make offer? Prefer to ship within the US; I don't know how well these will do going overseas.

Jumper settings / docs on AVIV qbus card needed

by p.gebhardt＠ymail.com

Dear community, I dropped over an AVIV card (model number 50-860), which seem to be a qbus tape-controller for drives with GCR-encoding. Two 50pin pin connectors typically used for PERTEC-systems are sitting on the front. Except for thirdy or so shops, google does not show up anything about this board. Bitsavers does not contain any AVIV-related documents, either. Does anybody have docs or at least jumper specifications of this board? That would be of great help in order to make use of it ! Kind regards and thanks in advance, Pierre ? ------------------------------------------------------------------------------- Pierre's collection of classic computers : http://classic-computing.dyndns.org/

PDP-9 Restoration at the RICM

by michael.99.thompson＠gmail.com

The PDP-9 will now execute the built-in diagnostic described section 3.7.7.3 of the maintenance manual. This diag copies the contents of the AR register go through the ADR to increment the value, then to the MB register and then back to the AC, AR, and PC registers. This means that much of the I/O bus logic, the CP timing, the registers, the ADR, and the Control Memory is working. Now we need to fix the core memory controller and start debugging the rest of the processor and I/O. -- Michael Thompson

CD-ROM drive "is offline. Mount verification in progress."

by spectre＠floodgap.com

Okay, VAX heads. I got an external SCSI cable for my VAXstation 3100 M76 and connected it to my old Apple SCSI CD-ROM that boots pretty much anything in my collection (Apple, SGI, you name it). At the chevron prompt, >>> b/r5:10000000 dkb500: -DKB500 [...] OpenVMS (TM) VAX Version X7G7 Major version id = 1 Minor version id = 0 [...] PLEASE ENTER DATE AND TIME (DD-MM-YYYY HH:MM): 13-JAN-2013 16:14 [...] %SYSTEM-I-MOUNTVER, DKB500: is offline. Mount verification in progress. It just sits there. So I tried it without the /r5 bit: >>> b dkb500: -DKB500 [...] OpenVMS (TM) VAX Version X7G7 Major version id = 1 Minor version id = 0 [...] PLEASE ENTER DATE AND TIME (DD-MM-YYYY HH:MM): 13-JAN-2013 16:20 Configuring devices . . .

Update to PDP-8 Spacewar to resolve VC8/E issues

by lbickley＠bickleywest.com

I had often run D.E. WREGE's version of Spacewar! on my PDP-12. But when I tried to run it on my PDP-8/E with a VC8/E and DEC VT01 (Tek 611), I would get flashing artifacts on the screen in addition to the normal display. I initially thought I had a hardware problem - but I could only get my VC8/E and VT01 combination to fail while running DEC's VC8/E diagnostics by setting the timing switch on the VC8/E incorrectly. When I initially looked over the VC8/E code in SPCWAR, it looked O.K. and I thought the problem was likely in the clock or interrupt code. After reviewing it extensively and not finding an issue, I tried multiple hardware clocks (EP, EC) and various VC8/E settings without success. Finally, I revisited the VC8/E code in SPCWAR - and the problem turned out to be a subtle bug in the VC8/E code. According to DEC's VC8/E writeup in the LAB 8/E manual, a "wait for done" should be given AFTER the last LOAD command (X or Y) is given and BEFORE the intensify command. In other words the code should be: TAD X /Get X coordinate DILX /Send to VC8/E TAD Y /Get Y coordinate DILY /Send to VC8/E DISD /Skip on done JMP .-1 /Wait until done DIXY /Display (Intensify) XY point ... The original SPCWAR code it was: Get X DILX /Send to VC8/E Get Y DILY /Send to VC8/E DIXY /Display (Intensify) XY point DISD /Skip on done JMP .-1 /Wait until done Because of the above coding error, the VC8/E analog output would not "settle" the correct amount of time (which for a VT01 is about 80 microseconds) because a DIXY command was given immediately after the DILY. This error created artifacts on the screen because the intensify command was in effect while the VT01 was still in the process of moving it's "beam" to the correct location. BTW: Slower displays, such as the VT01/Tek611/Tek613, do NOT need a clock to slow down Spacewar to an appropriate speed. If you would like a copy of the corrected SPCWAR.PA or a listing (SPCWAR.LS), you can get them via anonymous FTP to bickleywest.com or via your browser at ftp://bickleywest.com/pdp8_spcwar/ While I was at it, I also added an assembly option to start SPCWAR in Spaceship mode (per the original Spacewar!) as opposed to UFO mode.

OS/8 RK05 Disk Copy

server migration beginning

by jwest＠classiccmp.org

Yes, I'm running far far behind schedule with our new datacenter buildout. I'm finally to a point where I can start migrating classiccmp-related stuff. I'll be migrating the classiccmp-related websites that we host first (but not the main classiccmp.org site and subdirectories therein). That will start tonight probably. Anyone who has classiccmp-related websites hosted on classiccmp.org server, please do not make any changes to content over the next few days - that would make it easier on me. Also, while we provide DNS for most of the domains on that server, there are a few there that are using some other dns servers. If that is the case, please make an effort to respond quickly with regards to changes in A records. Several people contacted me a month or two ago about hosting additional classiccmp-related sites. I have those emails in a separate mailbox and will be getting back to each of you after the final classiccmp migration is done. After the websites are moved, but before I get ready to migrate the mailman/list setup, I'll post another update at that point so you're aware of the impending migration. Best, Jay

Looking for: IBM 5110/5120 I/O bus terminator

by derschjo＠gmail.com

Subject line says it all -- and I know this is a long shot. Anyone have one going spare? Finally got my 5120 working (after scrounging a keyboard, display, and an ROS board from a parts machine*) and of course I had no idea that a terminator was required in order for the internal drives to function. Iimagine these are hard to find, but I haveto ask... Thanks as always, Josh (*stillneed a Command/Language ROS board since it turns out my 5120 had not one but two bad ROS boards, but I've borrowed it from my 5110 for the time being. I'm assuming that it's pretty much impossible to repair these things...)

TRS-80 Model II Fixed Disk Controller Support

by ball.of.john＠gmail.com

>Some of the controllers also provided power on the control? Cable to power >on secondary enclosures. Technical bulletins state that yes the cabling for a second drive is modified to accomidate for the system to power on the external drives by means of a relay. If you didn't get the memo and you attached a second drive you would be greeted by a resistor on the drive burning out. :)

the Internet has turned 30 years old

by tom_a_sparks＠yahoo.com.au

" 30 years ago, at flip of a switch, the internet as we know it WAS BORN How TCP/IP nearly fell at the first hurdle By Gavin Clarke ? Get more from this author Posted in Networks, 3rd January 2013 08:59?GMT Thirty years ago this week the modern internet became operational as the US military flipped the switch on TCP/IP, but the move to the protocol stack was nearly killed at birth. The deadline was 1 January, 1983: after this, any of the Advanced Research Projects Agency Network's (ARPANET) 400 hosts that were still clinging to the existing, host-to-host Network Control Protocol (NCP) were to be cut off. The move to packet switching with TCP/IP was simultaneous and co-ordinated with the community in the years before 1983. More than 15 government and university institutions from NASA AMES to Harvard University used NCP on ARPANET. With so many users, though, there was plenty of disagreement. The deadline was ultimately set because everybody using ARPANET was convinced of the need for wholesale change. TCP/IP was the co-creation of Vint Cerf and Robert Kahn, who published their paper, A Protocol for Packet Network Interconnection in 1974. ARPANET was the wide-area network sponsored by the US Defense Advanced Research Projects Agency (DARPA) that went live in 1969, while Cerf had been an ARPANET scientist at Stanford University. The military had become interested in a common protocol as different networks and systems using different protocols began to hook up to ARPANET and found they couldn?t easily talk to each other, Cerf, who today is vice-president and "chief internet evangelist" at Google, announced the 30th anniversary of the TCP/IP switchover in an official Google blog post titled "Marking the birth of the modern-day Internet". The 1983 deadline?s passing was anticlimactic, Cerf recalls, considering how important TCP/IP became as an enabler for the internet. Cerf writes: When the day came, it?s fair to say the main emotion was relief, especially amongst those system administrators racing against the clock. There were no grand celebrations?I can?t even find a photograph. The only visible mementos were the ?I survived the TCP/IP switchover? pins proudly worn by those who went through the ordeal! >Yet, with hindsight, it?s obvious it was a momentous occasion. On that day, the operational Internet was born. TCP/IP went on to be embraced as an international standard, and now underpins the entire Internet. It was a significant moment, and without TCP/IP we wouldn?t have the internet as we know it. But that wasn?t the end of the story, and three years later TCP/IP was in trouble as it suffered from severe congestion to the point of collapse. TCP/IP had been adopted by the US military in 1980 following successful tests across three separate networks, and when it went live ARPANET was managing 400 nodes. After the January 1983 switchover, though, so many computer users were starting to connect to ARPANET - and across ARPANET to other networks - that traffic had started to hit bottlenecks. By 1986 there were 28,000 nodes chattering across ARPANET, causing congestion with speeds dropping from 32Kbps to 40bps across relatively small distances. It fell to TCP/IP contributor Van Jacobson, who?d spotted the slowdown between his lab in Lawrence Berkeley National Laboratory and the University of California at Berkeley ? just 400 yards and two IMP hops apart ? to save TCP/IP and the operational internet. Jacobson devised a congestion-avoidance algorithm to lower a computer's network data transfer speed and settle on a stable but slower connection rather than blindly flooding the network with packets. The algorithm allowed TCP/IP systems to process lots of requests in a more conservative fashion. The fix was first applied as a client-side patch to PCs by sysadmins and then incorporated into the TCP/IP stack. Jacobson went on to author the Congestion Avoidance and Control (SIGCOMM 88) paper (here) while the internet marched on to about one billion nodes. And even this is not the end of the story. Years later, in an interview with The Reg, Jacobson reckoned TCP/IP faces another crisis - and, again, it's scalability. This time, the problem is millions of users surfing towards the same web destinations for the same content, such as a piece of news or video footage on YouTube. Jacobson, a Xerox PARC research fellow and former Cisco chief scientist, told us in 2010 about his work on Content-Centric Networking, a network architecture to cache content locally to avoid everybody hitting exactly the same servers simultaneously.

HP 3000 microcode

by jdbryan＠acm.org

Does anyone have a copy of the "HP 3000 Series III Microprogram Listing Manual" (part number 30000-90136)? Bitsavers has the Series II microcode manual (30000-90023), and while that is helpful, it's not authoritative for the Series III. Thanks. -- Dave

Need help with a 11/23+ and a M8061 RL02 card.

by g-wright＠att.net

The system has M8189 cpu M8067 memory 256k M8029 RX02 M8061 RL02 M8639 HD controller Everything works except the M8061. Jumpers are set to Factory default. I did add the Q22 jumper just in case. There is always a chance its a bad controller card. The drive will come on line but that's about it. If I try to boot from it. i get an error, 'no controller' . If its running under RT11, booted off the RX02 , I get 'cant read directory ' Any words of wisdom out there Thanks, Jerry

TerminalsWiki: University terminal rooms

by legalize＠xmission.com

I imagine that UDel wasn't the only university to have a public terminal room. I created this page for UDel terminal history: <http://terminals.classiccmp.org/wiki/index.php/User:Legalize/UDelTerminals> If anyone else is interested in capturing the history of other terminal rooms at other sites (commercial, government, or educational), that would be a great addition to the wiki. Right now this is an article in my user space, but it could easily be moved to a more public space if others contribute similar articles. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

TRS-80 Model II Fixed Disk Controller Support

by ball.of.john＠gmail.com

>When this happens with a floppy drive, it is often due to the data cable having >being put on upside down, causing all the active signals to be grounded and >resulting in the drive being selected all the time. Perhaps a similar cabling >issue could cause this with an ST-225? I had the same idea until I switched the drive ID from 0 to 1. The BUSY light is now off and remains off on the drive until I tell DISKUTIL that the drive I want to work with is on channel 1 and not channel 0, at which point it probes for the drive (if it finds nothing it says the drive is not ready and asks to specify another drive), the BUSY light comes on and we get the same issue as before where it knows there's a drive but it can't format and says the disk is bad. The light WILL go out if the system reset is toggled which is probably because the controller is reset in the process. The cabling is keyed on the edge connector side and pin 1 is noted on both the ribbon cable and the header on the disk controller so there's no probable chance the wiring is wrong. I don't see why it could be trying to find an existing error map AFTER I specify what the factory had printed on it. It would make more sense to search for that BEFORE it prompted me to specify it. (http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/CRW_778 9.jpg) It could be ignoring it like you said but there's no way to try with a differently formatted disk at this time. Unsure if WRITE PROTECT is stuck. Seagate's own papers don't even mention a write protect jumper so I assume it simply does not exist for the drive. (ftp://ftp.seagate.com/techsuppt/mfm/st225.txt) I also don't see WRITE PROTECT listed as a pin on the ST506/412 interface cabling.

TRS-80 Model II Fixed Disk Controller Support

by ball.of.john＠gmail.com

According to this website (http://nemesis.lonestar.org/computers/tandy/hardware/storage/mfm.html) I finally managed to get hold of a Type 4 hard disk controller for the TRS-80 Model II/16/6000 family of computers (which looks like this: http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/CRW_7791 .jpg) Sourcing the external drive enclosures for Tandy systems is near impossible unless you have a lot of spare money handy so I instead did some research and mounted a Seagate ST-225 INSIDE the computer on a custom made mounting bracket over the PSU. (http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_276 9.jpg) The drive is a known good drive and formats and boots under MS-DOS. In order to run it under Xenix 1.03 I need to format it again using DISKUTIL. The controller can see the drive and seems to know it's ready but the problem is that the utility instantly fails the entire disk the moment you start the format. (http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/CRW_779 0.jpg) Tried with other ST-412 interface drives (full height, half height and 3.5") and they all do the exact same thing. Lonestar.org states that the '225 SHOULD be compatible with my controller. I looked up any documentation I could find and I see nothing about any sort of configuration the controller that needs to be set to support the drive. It should just plug in and work. The only thing I seem to find odd is the BUSY light on the drive is stuck on when the controller is attached which seems suspicious. Anyone here got a slue how I should be tacking this problem?

Recovering DC42 images?

by IanK＠vulcan.com

Hi all, This is one I've been working on for a bit without success, and I'm hoping the community has some ideas to offer. I'm attempting to recover the Lisa Xenix images on BitSavers so I can boot up a Lisa for an exhibit. I've managed to get the images onto a Mac IIci over the network (rather than through the dance of PC to Mac file formats), but DiskCopy 4.2 doesn't recognize them. I used the boot.dc42 image on LisaEm and got it to boot as far as it will (Ray acknowledges in the documents that Xenix doesn't work on LisaEm yet), but of course the emulation is likely written to the image: still, it suggests the images are likely OK. I found information that suggested it was necessary to use an older Mac to generate the correct disk format: I've formatted my 400K disks on a Mac Plus under System 6.0.3, and run DC on that Mac, too. Still no joy. Any suggestions? Thanks -- Ian

Difference between RSX-11M and M+ (was: What PDP11 OS in 20MB Disk Space)

Johnny (if he's montoring) > can expound. Since my name was mentioned... There are plenty of differences. Virtual terminals for one. Which also means that only M+ have batch queues. Named directories. Logical names. Variable send/receive. Secondary pool. Split I/D space support. Supervisor mode libraries. Accounting. Online reconfiguration. Mixed massbuses (probably not that big win today, when people run simulators anyway). Memory is managed slightly differently. I think that only M+ have disk shadowing and disk caching (also perhaps less used in emulated systems). Lots of tasks end up having more memory available in M+, which means they can handle more data, or have more capabilities. This also affects things like SYSGEN, which in M+ is rather more user friendly. There are probably more things, if I think some more. But this gives a fair idea. M+ is basically more. > I ran 11M (non-plus) on an 11/34 for many years. Rock solid, fast, > very nice OS. Agree. 11M is fine. It's just that if you can run M+, I'd recommend it. But it do require much more of the hardware. It takes way more memory, and it requires certain features in the CPU, that 11M do not. 11M can be run on basically any PDP-11, as long as you have atleast about 56K of memory (Better with more, of course.)

Wait! There's more including MS-DOS 1.25!!!! was Sanyo MBC-550 (Yuck!) software available

by rigdonj＠intellistar.net

I'm still digging. I found more 550 stuff. I think this is everything that came with the 550. Here's a chance for you 550 owner's to get the whole set at one shot! Original DS-DOS box and invoice. Original Sanyo Easywriter ver 1.3 disk Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4 are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1 Original Sanyo disk box with all three original disk of set A, WordStar and CalcStar and a backup copy of DS-DOS. Two card board dummy disks used to protect the floppy drives duing shipment. Joe > >A few weeks ago we were talking about the Sanyo 550 series and someone mentioned one of the alternates operating systems that supported 80 track drives in the 550. I said that was DS-DOS by Michtron. > > Today I found an old Sanyo disk package with four disks for the 550. One of them is DS DOS 2.11, one is InfoStar, one is MailMerge/SpellStar and the other is a disk of misc utilities. The first three are original disks. In additon, the InfoStar, MailMerge/SpellStar are Sanyo labeled disks that came with the 550. If anyone wants them, trade me something I can use and they're all your's. > > Joe

Sun 2/120 Front panel

by earl＠baugh.org

Howdy, I'm looking for a source for a front bezel / plate / panel for a Sun 2/120. Anyone happen to know where I might be able to obtain one? (I'd also be interested in the correct Mouse / Keyboard that goes with the Sun 2 series) I'm slowly working on restoring it, and the panel is the major missing piece. (I just recently found a replacement power supply, so I hope to be able to get it to boot shortly...) Thanks. Earl

SCSI over UTP, i.e. extender

by marcogb＠xs4all.nl

Purely out of curiosity, is anyone aware of the possible existence of LVD/SE SCSI (e.g. HD68) over UTP (RJ45) extenders? I'm aware that one normally goes for FC, or a SCSI<=>FC bridge, but those tend to be rather pricey. - MG

WTT/WTB: SGI IP59 quad-processor CPU board

by marcogb＠xs4all.nl

Does anyone have this, willing to sell or --- more ideally, for me --- willing to trade a SGI IP59 quad-processor CPU/node- board? (P/N: 030-1989-003) I have several (non-SGI) systems of interest, Alphas (PWS 500au's and DS10s), but also Sun SPARCs (e.g. Ultra 10) and also at least one HP Integrity rx2620 "Montecito" (largely maxed out, with 24 Gbytes RAM) to trade. All of the above are max'ed out, in terms of 'specs' & configurations, plus there are many (PCI, PCI-X, AGP, etc.) options available. I also have an IP53 dual-processor CPU/node-board, as a possible 'replacement' (in case an IP59 board would have to be removed from a working system) and may even have a quad-processor one (i.e. the one I currently have installed). I'd also like to emphasize, to avoid confusion, that these are things I have to offer. Not so much things I'd like (or deem sensible) to trade 1:1. The reason I'm looking for this part, as well as other parts, is because I'm trying to get as much out of my system as possible, as I'm working on my portfolio as a graphic designer. Either way, please don't hesitate to contact me. I'm open to ideas and offers. Thanks in advance. - MG

FS: 2× Compaq DS10

by marcogb＠xs4all.nl

Two Compaq AlphaServer DS10 systems, each with a 466 MHz EV6 processor and 2 Gbytes RAM (I can also reduce it to, say, 256 Mbytes). There are various options additionally, including SCSI RAID (e.g. Smart Array 5300 or even Smart Array 6400), GbE (DEGXA, original and/or modified), stock ELSA GLoria Synergy, various Radeon 7500 (also All-In-Wonder), NEC USB, audio cards and more. One of the two DS10s 'as-is', as it may have a faulty CD-ROM drive (it's also missing its 'badge/name plate' with "ALPHASERVER DS10" on it, below the "Compaq" logo, in case you should care). The skins are all intact, in good/excellent shape and included. I have various options to offer. In any event, please contact me for more information, offers or potential trades (I'm in particular looking for SGI parts). I can also show pictures and arrange a 'test drive' or 'tour' via SSH or Telnet. The systems are located in the Netherlands and I'm willing to ship (internationally). - MG

FS: HP AlphaServer DS15

by marcogb＠xs4all.nl

Anyone interested in a barely used, mint-condition, HP AlphaServer DS15? Equipped with a 1 GHz 21264C/EV68CB, maxed out with 4 Gbytes RAM, (*original HP*, active-cooled, noise-free) ATi Radeon 7500, (rare) DS15 audio option, DEGX2 (dual-port Gigabit Ethernet) and a hot-swap front access disk cage (I may also be able to include two disks and sleds, contact me about that). A nice touch, especially for those used to the DS10, is that SCSI (KZPEA) is on-board. Besides the on-board KZPEA, I also have a KZPDC (HP/Compaq Smart Array 5300, Ultra160 SCSI RAID HBA) and/or KZPEC (HP Smart Array 6400, Ultra320 SCSI RAID HBA), as well as an HP/Neterion XFrame 10GbE NIC.
