Now that I have a working PDP-11/23+ system, I find (as I should have known from many similar projects) that the "fun" was really in accumulating the pieces and getting it working. I don't really have anything I want to DO with it (although I suppose that is the whole point of classic computing :) but I have run ADVENT. anyway I was wondering if someone else would be interested. In brief, it's an 11/23+ KDF-11BA CPU (the chassis front panel is embossed "11/03" though) with max 4 Mb RAM, two RL02's, VT220 and a 16-line serial card. Has a pack with RT-11 v5.mumble up and running. I have what appears to be a TSX-Plus pack but don't know how to generate a working system. "Corporate cabinet" in decent shape. Paint on the RL02 fronts has seen better days. Can send pics this weekend. It's in West Plains, MO (65775), about 200 mi southwest of St. Louis, 100 miles southeast of Springfield, MO. If I could find someone to help me get it down the stairs I could deliver it to St. Louis (or I could disassemble it if necessary and carry the pieces down) since I work there every week. Let me know if there's any interest - contact me offlist and make me a reasonable offer. I hate to see it just gathering dust and my PDP-8/A system (two RL02's and ASR33 Teletype, running OS/8) is enough vintage computing hardware for now :) -Charles

hams on classiccmp

by shoppa＠trailing-edge.com

N3QE, formerly KA0BTD. Got my novice ticket at age 10. I was basically inactive for 20+ years from entering college until 2007 when I started dragging out the old Heathkits from my childhood and hanging wires in the trees. Ironically, it was computers and girlfriends in college that distracted me from radio; looking back I can see that compared to ham radio they were a waste of time :-). Especially in winter I hang out on 80M CW many evenings and manage to do something for many of the big CW contests/events. Even though I've got a lot of old rigs, my preferred rig is a lowly HW-16 and my antenna is a 130 foot doublet hanging between two trees, 90 feet up, and fed by ladder line. Tim

offer: old book

by rtellason＠verizon.net

Got this book here, maybe somebody would care to take it off my hands and offer a little something for it? Title is "Infor World PC Secrets", by Caroline M. Halliday. Copyright date is 1992. There seems to be a couple of 5.25" floppies in a sealed pouch inside the back cover. Front cover says a whole lot that I won't detail here but includes "Covers DOS 2-5 & Windows (I'm assuming they mean 3.1 here), MCA, EISA, 286, 386, & 486 PCs". Anyone interested please feel free to contact me offlist. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Without knowing what the items are, there's no way I could know how much it would actually cost to ship them to the UK. It may be that $30 is a reasonable _difference_ betweeen the UK and US shipping costs. The things that annoy me are sellers who have _ridiculously_ high shipping costs. There's a guy who's got some manuals for sale -- fairly thin manuals, no binders or anything like that. His shipping charge to the UK is something over \pounds 60.00. Now, I relaise that filling in tyhe customs form for overseas shipping takes time, and that it's reasonable to have to pay for that. But, darn it, that charge is excessive compared to the shipping charged by other sellers for much larger/heavier/more delicate items. As with others here, I get annoyed when things are not packed adeguately and arrive damaged. I would be happy to pay more for proper packing on a rare device. And I wish sellers would (a) get in touch if there's a delay in sending out the package, and (b) would actually let me know when they send it. If I am not in to receive the parcel, it gets taken back to the post office or sorting office then (a) I have to go and collect it and (b) it appears such packages are much more likely to be damaged. So I want to be in when it's delivered. On the other hand, I don't want to have to wait around for a parcel that's not even been sent yet. A short e-mail from the seller 'I sent it on $date' would be much appreciated. -tony

When I acquired my PDP-11/34, I also received a Centronics 503 printer, along with an entire case of ribbons for said printer. They have a part number of 63002293-5001. It's a black nylon ribbon on two spools. These are NOS. I haven't been able to identify anything that uses them - and I mean anything, because I can't find anything on the Web about the Centronics 503, either. Does anyone have any leads on this?

They have been cherry picking the incoming stuff for years. The big one around here is Computer Recycling Center, next to Weird Stuff (who is in the same biz). Most modern PC stuff they get goes to schools, they eBay the stuff they can get money from, and put the dregs up for sale on Saturday mornings. Feeding frenzy at 9:00 AM when they open. I wander by every once and a while to pick up cheap PCI cards, or the odd bit of old software no one else wants. Most of the store front junk stores around here disappeared as manufacturing left the valley, and the bottom feeders from bankruptcies go directly to eBay now with no retail presence.

offer - OS/2 for the PDP-11

by dgahling＠hotmail.com

Yes, you read that correctly. I have in my possession a TK-50 tape for the PDP-11 system which contains none other than OS/2 operating system. Many people have claimed this never existed. But I have the tape! I had done a directory dump of it and can supply it. One other person who's checked the directory listing has said it is authentic. I'm not sure what to do with it, and I believe IBM made OS/2 open source, so technically it should be "free" of it's chains maybe someone can turn it into something useful, or just run it and have the most unique PDP on the planet, I don't know... whatever :) anyhow, it's a really weird bit of computing history, and I'd hate for it to be lost. it should be in a museum :) Dan. _________________________________________________________________ Use fowl language with Chicktionary.

Take a look at item # 130281137792 -- an HP2647A terminal with no keyboard, some rust and a fairly bad case of screen rot. The seller listed it yesterday for $900 initial bid or $1500 buy-it-now. I politely sent them a note explaining that their prices were an order of magnitude too high, particularly considering the condition of the unit. So what did they do? Dropped it to $400 opening bid. Yeah, right. Terminals are getting scarce, but not *that* scarce -- its more likely that people's interest in serial terminals would dry up before they'd pay through the nose for a 2647A. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

A few newb/background questions about the XKL TOAD

by aek＠bitsavers.org

> 4. Do the freeware copies of TOPS-20 floating around TOPS-20 is not "freeware". There is nothing in the software distributions that claims it is so. XKL bought the rights when DEC got out of the 36-bit business. Not asserting your rights to something is quite different from an assertion that it is "freeware". This is also one of those rocks you really don't want to turn over..

How to tell differential scsi drives and cards apart

by teoz＠neo.rr.com

Is there an easy way to tell if a SCSI controller or HD is LVD or HVD? My understanding is that HVD was the first type used and was just called differential F/W and then LVD came out so the old standard was then called HVD. I have some SUN Symbios 22802 cards coming in I wanted to use in a SUN Ultra Sparc 5 and I think those are HVD (advertised as just differential and I didn't think to cross check). Everything I have is SE/LVD.

PDP-8 front panels

by pontus＠Update.UU.SE

PDP-8s has been used for just about everything and have almost as many different front panels. This is one of the more esoteric ones I've seen: http://www.flickr.com/photos/joachimschwanter/414790437/ Is this a one off custom build? Rebuilt by a PDP-15 lover perhaps? Appearantly it was showcased at VCF Europe in 2008, maybe someone was there and can shed some light on it. Hope this is tech enough for cctech :) Cheers, Pontus.

I don't collect PDP-10 stuff. I collect PDP-8 and PDP-11 stuff (along with some VAXen and other DEC things). Johnny Eriksson is also in Stockholm, but I didn't know he had taken care of the KA and KI systems. And as far as KI systems goes, Peter Lothberg still have KICKI, so Bygg don't have all of those. Admittedly a technicality since if they aren't stored at the same place, it's still in the same town. So on a "world" scale, they are perhaps all "here". But maybe Rich Alderson meant just "near" as in physically not far from, even if not in his possession. The only KA-10 system I know of, by the way, is KATIA, which was owned by Stacken. I had/have an account on it, but I don't think it's been powered on for close to 20 years now. (The name KATIA is a pun in Swedish, by the way.) >> > Oh. I didn't mention that, did I?

A few newb/background questions about the XKL TOAD

by madcrow.maxwell＠gmail.com

There's recently been a lot of talk about the XKL TOAD, and I, as an interested lurker had been holding my tounge, despite having some questions. No more. 1. How does the XKL compare with the Jupiter? Given that they both had features like an extended address space, was the XKL basically a "if DEC won't build it, we will" type of thing? 2. What the difference between the XKL TOAD and the various SC systems? Was SC a reseller/packager/intergrator or did they have their own seperate "Super KL"? 3. Does KLH10 support any of the XKL extensions? 4. Do the freeware copies of TOPS-20 floating around the internet have any support for these extensions or were those proprietary to the copies of TOPS-20 that shipped with TOADs? Thanks for answering this barrage of silly questions, Mike

As I mentioned the other night, I'm peripherally interested in an FPGA-implemented -10, but I have a definite budget - I'm willing to roll a lot of my own hardware (loose parts, soldering, etc), but I really can't justify more than a few hundred $$$ in total. I certainly can't assist with the VHDL-end of things. Once things get past the experimental stage and it's booting TOPS-20, I'm likely to be more interested. My requirements are pretty loose - if it runs one of the extant compiled versions of MDL Zork, I'm in. -ethan

Old Software Rights

On 15 Jan 2009 at 12:40, Paul Koning wrote: Copyright these days is a LOT longer than 30 years.

Copyright is implicit in all works produced today, whether or not stated. Almost all software published during the 1970s has a copyright notice embedded. After the Uruguay Round of the GATT talks, copyright for works published after 1923 whose copyright was in effect as of the URAA is 75 years, later extended to 90 by the Sonny Bono Copyright Extension Act (yes, he, or rather his widow, of the other half of Cher. Reportedly, Mary wanted to make copyright perpetual, but was informed that such a move was distinctly unconstituional). Read about the law at http://www.copyright.gov. Rules outside of the US may be substantially different. In particular, after the fall of the Soviet Union, legislation was passed in the US to allow works of Soviet origin to be removed from the Public Domain (so-called "restored" copyright. Who says you can't put the toothpaste back into the tube?). However, they may still be freely copied in Canada. Bottom line is that there is no such legal entity as "abandonware" and you promulgate the idea at your own risk. While economic damage is part of civil actions brought by copyright holders, it is not the whole picture. Unlike patent infringement, copyright violation in the US is a criminal offense under the DMCA. Just because no one seems to be using IBM 5160s to run Harvard Presentation Graphics from 360K diskettes does not make it legal to copy and distribute it. It's not up to the infringer to declare whether or not a work has any value. So you may have to wait until, oh, 2075 or so before you can legally hand out those old copies of Lotus 1-2-3, assuming that our Congress isn't goaded into action by the Empire of the Mouse again. As a musician, I'm continually frustrated by publishers of old copyrighted material (some stuff going back to the 1930s) who declare a work to be "permanently out of print" and will not authorize a copy (for a fee) nor provide me with a copy that they created from their archives. Currently, the only resort left is to pick some other work. There's nothing in copyright law to force the owner to publish or support his works, nor give permission to copy. And the notion of "Fair Use" is a very slippery slope--if you guess wrong, you're fully exposed. Cheers, Chuck

NCCC - Sunfire V100 / Solaris

by quapla＠xs4all.nl

Tom, Best way is to install Solrais 8, 9 or 10. Then install the SUNWlomu, SUNWlomr & SUNWlomm packages followed by patch 110208-22. Then use the lom tool to manipulate the lom config to your likings. BTW, the patch has the latest firmware for the lom, so you can also upgrade it if wanted.

"Tyrotek" analog computer

by hilpert＠cs.ubc.ca

I'm currently working on refurbishing a small analog computer from the mid-60's. It has the name "Tyrotek" on the front panel, in the middle of a sine wave curve. (My) web searches turn up zippo about this name (other than some guy using the word as a moniker). The only other clue to a manufacturer is "Non Linear Mfg." in the foil of the printed circuit boards. No model number, no identification plate. While it is smaller for an analog computer and appears to be intended as an educational or training unit, it is built to industrial standards, with a nice sizeable plugboard using standard IBM plugboard wires, fiberglass PCBs, discrete FET-input op-amps, etc., so it's not just some gimmicky thing. Eventually I'll have a web page for it, but right now I'm curious as to it's manufacturer origins. Just a guess, but one line of speculation I'm making is that "Non Linear Mfg." may have been the manufacturing arm of Non-Linear Systems of digital voltmeter fame, and Tyrotek was a subsidiary of, or otherwise associated, with NLS. Comments / clues / recollections?

Commodore Pet 2001 Troubles

by jason＠havnet.net

Dear Fellow Enthusiasts ... Firstly, I must admit to being somewhat of a 'lurker' here reading with great interest the postings and never failing to be amazed at the shear amount of amassed knowledge on the subject. My thanks to you all. Is there anyone here that can help me with a Commodore Pet problem that is really starting bug me !! It is a Pet 2001 32N with a Computhink Pet II Disk Controller Board and a pair of Dual Computhink drives (Model : DKH 642-I). The machine starts up just fine and you can enter DISKMON by typing SYS11*4096 However, upon entering commands like $LOD,1,"FOO" the screen turns to a complete screen full of small squares - chequer board style. Upon the command $DIR,1 the screen briefly displays a boarder around the screen where the directory content would normally appear and as soon as the drive activates the screen turns to chequer board. I have done the usual of re-seating the IC's, and I am hoping this isn't failed ROM. Another clue maybe that for some reason, when the drives are activated, BOTH drives activate together, which obviously they shouldnt. I haven't yet gone to the lengths of scoping the control lines but will start there tommorrow evening ... Does this sound like a problem that anyone has enountered before? Are there any 'Petsperts' out there that could help get this machine back on the road? Thanks in Anticipation Jason Fitzpatrick www.ComputingHistory.org.uk

Failed bit on 11/05 core memory

by toby＠coreware.co.uk

Alas having got my 11/05 working, its developed a problem. Bit 5 on the lower 8KW of memory (it has two sets of G110/G231/H214 8KW cores) has failed and is always set to 0 Does this indicate a failure in the X/Y drivers? I have a spare set of G110/G231 cards, so I'm guessing swapping out the failed card will provide me with an immediate fix, although I would like to get the existing card repaired. How is the base address of core memory set? Are there jumpers on the boards or is it position in the backplane that determines its location? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Hi there, My TAXAN KS12R101S colour monitor for my Apple IIe is dead. A capacitor has exploded a long time ago, and electrolyte has corroded several parts. I have washed it in water, scrubbed the stuff off, dried it, and replaced 2 electros, but a resistor has corroded away to nothing, and I do not know its value. The monitor powers up, I can hear he EHT start, but no display. Does anyone know where I can get a circuit please. Regards Ray

Flexicord cables get bent... and stay that way

by aliensrcooluk＠yahoo.co.uk

This is cool, or is it just me? Anyway, I suspect there might be uses for these special cables should they cross-breed with a parallel cable or other retro cables :) Regards, Andrew B aliensrcooluk at yahoo.co.uk http://www.engadget.com/2009/01/13/flexicord-cables-get-bent-and-stay-that-… | Comments Ever have a cable you wanted to strangle? Well you're not alone, apparently. A company called E-Filliate issued a new series of USB, HDMI, Cat5, S-Video, and composite cables called Flexicord at CES this year which will bend -- and stay -- in any position you please, thus eliminating that frustration you must feel every time you plug in your camera or hook up your high fidelity sound system. The cables act like pipe cleaner or Gumby, so you can twist and shape them as you please, though apparently Pokey had to be killed and dissected so the technology could be obtained. Enjoy your new cable, murderers.

HVD SCSI Tape library

by jws＠jwsss.com

I have an elder setup I would like to plumb with cables, but do not have all I need. It is a tape library with 2 wide connectors, and an Adaptec 2944 in the host. I am thinking of a 3' or so wide cable (68 pin) with 3 connectors that are male, and each end with a female connector. I can terminate it at each end with the terminators I have, since the controller I have puts out termpwr. Any suggestions or sources or ideas. Anyone have such a beast to spare? thanks Jim

VIC-20 Mega-Cart

Anyone ever play with an IOtech Serial488/4?

by ethan.dicks＠gmail.com

Hi, All, I have this IOtech Serial488/4 IEEE-488 quad serial box here, found the manual easily enough, but haven't yet set it up. Does anyone on the list have any experience with one of these? If so, I'd love to hear about any lessons learned or "gotchas". For those that haven't seen one, it's rack-mount box with a 68B09, some ROM and SRAM, a pair of Z8530s, and a TMS9914 GPIB chip. It gives you four buffered serial lines on your IEEE-488 bus. They are still sold new, for new prices, and used for about 10% of that. It looks rather straight-forward to talk to, but I thought I'd ask in case there is some "notorious" feature of them. Given that I'm heavily loaded with PETs and not with HP equipment, I'll probably go that route. Thanks for any tales, -ethan

Memory/cache on the 11/70

by bqt＠softjar.se

Since there have been a few discussions about the memory/cache of the 11/70 now, I think I might make a few comments as well. When we talk about the MK11 memory, you need to remember that it's a separate memory box, and is not at all transparent to the 11/70. The 11/70 have a memory bus. This memory bus is what you would interface to if you designed your own memory which you put in the free CPU slot. The memory bus don't have any ECC. The ECC of the MK11 is totally located inside the MK11, and is not visible outside. The 11/70 memory bus only have parity bits. So you can skip all the ECC stuff if you want to play with your own memory "box" design. Pretend it's a MJ11 instead, which is simpler. Another detail is that memory refresh is also something that is internal to the box. None of that is visible to the CPU. And neither is memory rewrites in the case of core. Now, my memory of the 11/70 memory bus is fuzzy, since it's been quite a while since I was studying it. But the schematics and manuals are out there, so all of this can be read up on. But as far as I remember, the 11/70 memory bus is rather simple and asynchronous. The machine presents 22 address (actually 24 are defined, but the top two are always zero). You have 32 data bits. 4 parity on data, and probably also parity on address. You have a few control lines, and that's it. You have three types of transactions. Read, Write, and Read-modiy-write. With the 11/74 you also have an interlock function, but I guess that's a moot point since noone around here have an 11/74 CPU anyway. However, the 11/70 cache and memory controller presents quite a lot of overhead and slowdown. If you really would like to speed the 11/70 up (and you can, believe me), you would want to replace the cache and memory controller all together. Now, after reading a few comments here, I've finally understood the relationship between the SETASI PEP-70 and HC-70. The PEP-70 is 4 megs of memory. You can connect that to the 11/70 memory bus. The HC-70 replaces the cache and memory controller in the CPU. This makes the whole 4 Meg of memory look like cache. You hook the PEP-70 to the HC-70 instead. Nice solution actually. I wonder if (in theory) you could hook any memory box to the HC-70, or if the PEP-70 can work in two modes. One as a device on the memory bus, and one as a cache memory for the HC-70. Anyway, if someone were to design a memory system for the 11/70, the way I'd recommend is to go the whole way, since that's where the real gains are. Skip the memory bus and the original cache. The original cache is just 2 KB of 2-way associative memory. If you set up a 4 MB cache, the CPU can run at full steam the whole time, with a cycle time of about 150 nS, if I remember right. It is more complicated, though. You'll have access paths from CPU, Unibus and four massbus controllers to deal with. But it should definitely be doable (heck, SETASI have already done it once). I might be interested in such a project myself, since the 11/70s we have around here still are on MK11 boxes. I could deal with PCBs and design, but I'm very short on time, as usual... :-( No experience at all with FPGAs or any such fancy stuff. Johnny

FS: NeXT Turbo in Seattle WA area

by michaelgreen42＠comcast.net

I am getting ready to move and trying to lighten my load a bit. I have a working NeXT Turbo, 17 b/w monitor, keyboard, and mouse. It works great with a few minor issues. It boots but gets stuck on detecting network. Since I can't find my NeXTStep install CD's I can't log into it anyway since I don't know the password. Also the port where the mouse plugs into the keyboard has separated from the keyboard portion. It can be fixed since it's not actually broken but it will take more patience/time than I have or just a new keyboard. Looking for best offer. If you don't want the monitor due to shipping reasons I can take that off.

Interesting Folder

by wdonzelli＠gmail.com

I am culling thru some IBM docs, and came across a boring printer memo (for the 3203, all about print quality, big deal) bound in an interesting binder. It is a standard 1950s brown Accopress binder, but the tag on the front says "FRAME 41, XD-1 MAINTENANCE SUPPORT, GROUP 201-250". This cam from a gut that gave RCS a big pile of IBM docs (he was an FE) in the Boston area. XD-1 as in AN/FSQ-7(XD-1)? Mike? -- Will

DEC Direct Sales Catalog

by silent700＠gmail.com

I have a copy of this book: http://flickr.com/photos/chiclassiccomp/3178202349/ It appears to be from around 1979, and is chock full of part numbers and specs for hundreds of DEC products of the time, including rack parts, documentation kits, and even the DECMat carpet :) I would really like to get this book scanned, OCR'd and available to DEC collectors. My questions are: Has this guide, or one close to it, already been scanned? How rare are these guides? Does anyone out there have one? I would have to at least remove the binding in order to scan it (and at 140 pages I'm not going to mash each half-page against the scanner glass.) I'd really hate to destroy a book like this. If I'm careful, I can drill holes in the whitespaces, razor off the edge binding, and reassemble it as ringbound.

It's certainly possible that could be a problem, but I've been reading the MSV11-D user's manual (it's on vt100.net) and it doesn't have a jumper to disable the top page. Actually what it has is a jumper to _enable_ the bottom 2K of the I/O page, so you can have a tiny bit of extra RAM in systems without many I/O devices. The MSV11 manual says only "factory configured modules will not respond to bank 7 addresses..." and it then goes on to say how you can enable the lower 2K of bank 7 with the aforementioned jumper, but it's quiet about how it decides what a bank 7 address is (i.e. does it monitor BBS7 or the address bits?). The only other jumpers on the MSV11-D are for battery backup and to select the starting address. Thanks for the suggestions, but I'm afraid I'm still puzzled... Bob

Mac 400k floppy drive alignment?

by derschjo＠mail.msu.edu

Got myself an ancient external 400k mac floppy drive on the cheap that I'd like to use on my 128k mac -- after cleaning out the old dried lubricant and getting the drive mechanism running again, the drive works but will only read/write disks that it has formatted, which leads me to believe that the drive is out of alignment. How is alignment corrected on these drives? Thanks! Josh

I forgot what RSX does. Not sure > you could run that on an -05 anyway. RSX uses the side effect of R0 being shown on the data bus on a WAIT instruction as well. And yes, I think you could get RSX running on an 11/05. I don't think there was any PDP11 that couldn't run RSX, but it would be a rather specific RSX you would gen for it. I doubt you could boot any generic RSX system on that machine. Instead you would have to run the sysgen on another machine, and just boot the resulting system on the 11/05. Think unmapped RSX. That won't use any MMU. Still, you'd probably want the full 56K on that machine. > Sufficiently old RT11s should work on that machine. So would RSTS > V4A, if you can find an RK05 or RF11 or RP03 disk drive. :-) New versions of RT-11 should do as well, as long as you select a variant that don't need the MMU.

29F512 flash memory

by trag＠io.com

> Date: Thu, 8 Jan 2009 13:11:31 -0500 > From: "Danny Pham" <dpham at americanalphainc.com> > I'm using ChipMax programmer to flash EPROM 29F512 and for some reasons, > it > doesn't flash the program. Is there anything that you think I'm doing > something wrong? Please give me some advises. Are your chips DIP or PLCC? I ask because if you are using PLCC chips with an adapter, you may have the wrong adapter. The pinout relationship between DIP and PLCC is different for the 512Kb chips than it is for the 1 Mb chips. So a 32 pin PLCC to DIP adapter for 1 Mb flash will not work with 32 pin PLCC 512Kb chip. If it's not that, I can't help you. I'm not familiar with the ChipMax. I use a Needham. Oh, in general, make sure you have the correct make and manufacturer specified. Some of the Flash chips have a reset pin which must be tied high or they won't operate. Others don't, so getting the proper make and model selected in your software can be essential to getting your programmer to handle the reset pin properly (if present). Jeff Walther

Membrane keyboard connector repair advice? (Osborne 1)

by derschjo＠mail.msu.edu

Yet another small repair question -- Picked up an Osborne 1 with a non-functional keyboard. Upon opening it, I found that one of the plastic/membrane keyboard ribbon connectors had cracked partially through near where it plugs into the PCB. Since these ribbons are actually part of the membrane of the keyboard I can't just replace the cracked ribbon -- so the only option appears to be to re-cut the end of the ribbon cable and expose a bit of the conductive material. What's the recommended means to expose the conductive stripes at the end? I've tried gently scraping with the tip of an x-acto knife but it either does nothing or takes everything off the end :). Thanks! Josh

PDP-11/05 returns to life

by toby＠coreware.co.uk

I managed to coax my PDP-11/05 back into life today and ran a few simple programs on it successfully. As a result a few questions for the experts out there: 1. To get it up and running I had to replace its two fans both of which had failed which I did by scavenging another 11/05 chassis I have. Does anyone have any tips on reviving failed fans? Both spin freely by hand but when powered one hums heavily and the other reluctantly and somewhat noisily spins up (if kick started with a screwdriver). If recovery is impossible can anyone suggest suitable replacements? The current ones are labelled Super-Boxers 2. Is there a chasing lights program I can run on the 11/05? Would be nice to see it visibly doing something 3. At the moment the machine has 16KW of core (2 x 8KW planes). This together with the CPU fills all but the last slot on the Unibus (its a 5inch box so only 9 slots). I'd like to fit a DL11 so that I have some serial comms and ideally an RX11 as well so I can hook up my RX01 drives and boot RT-11. Can I make use of the 9th slot or does this have a special purpose? There is a lot of wire wrap going to slot 9 so I'm guessing its not suitable. 4. What versions of RT-11 is suitable for an 11/05 and what is the minimum memory to run it?

He has a client that needs to dispose of some functioning Wang equipment, namely: > The Wang CS and SDS drive and 2236 monitors, cables, etc > at my client's office will be tossed by mid January. The Wang CS was a late 80s incarnation of the 2200 MVP. The MVP is a microcoded machine that runs the Wang BASIC-2 dialect. It is also a timeshared system, as you can connect up to 16 terminals (that is what the 2236 thing is -- intelligent terminals with 8080s in them). The SDS drive is a 3rd party hard disk made by Southern Data Systems. I would suspect a cache of manuals and software come with it. It is located in Southfield, Michigan. The owner doesn't want any cash, just wants it gone as they are moving locations. If nobody claims it in the next few weeks, it will be turned back into sand. Email me and I'll connect you with Mike.

Ancient Mac file/disk preservation/archiving (was Re: Mac 400k floppy drive alignment?)

Good to know... I have plenty of late 68K and early PPC Macs handy, but wasn't sure what could or could not read 400K disks. > I still have the original MacWrite and MacPaint floppies that came > with my 128K... I think I still have those from somewhere (I couldn't afford a Mac when they were *NEW*, but I did manage one eventually. >... along with a lot of other good stuff (like the Banana PC 6000 Jr. > emulator for the Finder, and a CLI that would only run on a 68000). Nice. Those sound like fun. I know I have plenty of old 400K disks because I have yet to go through the boxes of floppies from my mother's shop. She ran "Academic Typing and Typesetting" for years, a few blocks north of Ohio State; and for the longest time, she used Mac 512K and 512Ke machines (eventually with Dove Snap boards), a couple of Mac Pluses, then finally settled on Mac SEs which she stayed with until she died in 1997. I don't think she had a single machine that I didn't open up to either repair or upgrade (or both!) over the years, including loading a "Plus" ROM set into her $5,000 original Apple LaserWriter. She never could get over the fact that her laser printer was always her most powerful computer. It wasn't until late that she had a Mac over 2.5MB of RAM. She moved up from IBM Selectric II typewriters, and to her, the Mac was foremost a machine for processing text. She never outgrew System 5 and whatever version of Word for Macintosh that ran on a Mac Plus-equivalent box even when all new Macs had color and more memory and disk in one machine than all of hers combined. She wasn't much for games, unsurprisingly, but in amongst stacks of student papers and dissertations, I hope to find a few gems tucked here and there. Her entire collection of floppies plus images of all of her machines would scarcely make a dent in a CD-ROM, so it's more the time it's going to take to read things in than anything else. Presuming one has a few hundred floppies to read in, does anyone have any favorite apps to recommend? I presume, like for the Amiga, there are preferred floppy image formats that could be used to either reconstitute real media or to feed to an emulator. Obviously, any imaging program should be able to do that, but it doesn't hurt to specifically ask. Among the (not uncommon) things I recall from her machines in the 1980s are MacPuke, the "Jive Finder", and a variety of PICTs of various anti-DOS posters. What I'm looking forward to is finding things I've long forgotten were there. -ethan

HP9836 hardware. software and manuals availability

by srp＠saslab.net

I have a large collection of hardware, software and manuals relating to the HP9836 computer. The following items are available to anyone who would like them and who could collect them from Buckinghamshire. I will only give an outline of the items available although \I can provide more detailed listings on request: 1. 5 Hp9836 computers of which 2 are fully functioning. The other 3 have various failed subsystems but they could easily be cannibalised into 2 working systems. 2. Approximately 8 5.25 disk drives, all failed and in need of repair. 3. Full manual sets for Basic and Pascal in t 2 versions of each. 4. A collection of memory cards and math coprocessor cards. 5. Both 3.5 and 5.25 original operating system disks. 6. A collection of 7470 and 7475 plotters most of which are working. 7. A collection of various Thinkjet printers and other HP printers, 8. Various HPIB cables 9. IEM Fortran77 compiler and manuals. Several 9122 3.25 disk drives I have been using these machines for 25 years and have recently changed to Windows based systems. I do not have the heart just to throw these items away so please let me know if you need further details or have any interest in these items. Marek Pawlik

IOB6120

by drb＠msu.edu

Recent discussion of the SBC6120 and the IOB6120 reminded me that I've been wanting an IOB6120, so I spent a little time looking into having boards fabbed. I talked to Jim Kearney, who said he has no objections. It looks like 25 pre-sold boards at $28 is a workable price. Though less likely, 50 boards pre-sold would be make it $16. Issues: I'm not currently able to front the cost, so it would have to be a pre-pay deal. I'm willing to do the footwork to order boards, but I'm not ready to tackle kitting full parts sets. J.C. Wren said he believes that at one point there may have been issues sourcing flash chips. If original or compatible parts are no longer available, then there's no point. It'll take me approximately a dozen round-tuits to check all of these. Perhaps someone else is intimately familiar with the parts and could do it, or we could split them up among a group and each check a handful? According to Jim, this board is a non-trivial build. I think I can probably pull it off, but I'm not about to start building 25 of them for others. This may limit the number of folks interested in buying. So: Discussion of the above issues (or others)? How many would buy IOB6120 boards (I'll try to keep score)? Cheers, De

Reply - Re: more housecleaning -- floppy disk manuals

by FJGJR1＠aol.com

Thanks Chuck for the info! When I saw this post on these manuals, I thought of you. Looks like they are claimed. It is me GADFRAN from _www.vintage-computer.com_ (http://www.vintage-computer.com) . I tried to respond to your message but my system was acting up again on that site. I only have the usual Tandons for Kaypros - TM100-2 and TM100-4. Frank In a message dated 1/7/2009 11:19:01 P.M.

The -4 is 96tpi; the -4M is 100 tpi. Drives that can do 96 tpi are a dime a dozen; 100 tpi is a whole different matter--always useful to have a few extras. Was there ever a half-height 100 tpi floppy drive? I've never seen one. Cheers Chuck **************New year...new news. Be the first to know what is making headlines.
