corestore here.... yes I have an RP11, and an RP15. And as of a couple of weeks ago, I have an RP02 and two RP03s! Strange that they should now turn up in two different places almost at the same time. Keep me updated - I intend to get my drives working, if you decide you don't need your drives any more, talk to me first! I also have RP04s, which are almost as interesting, but have a massbus interface which makes them a lot easier to get working...

For the swedes: Free digital LP25

by pontus＠Update.UU.SE

Hi At work we have a non-working LP25 that is threatened by dumping. It wont go away soon, but at this time next year it is probably gone. I'm told it suffers a standard fault of a worn out drive wheel. If you want it, its free for pick-up. http://vt100.net/docs/tp83/full1602.jpg Cheers, Pontus.

Andromeda Systems (ebay)

by tshoppa＠wmata.com

Andromeda sold some cool Q-bus chassis with drive mountings and power supply integral. I think the one in the E-bay auction is two 3U sized cabinets either just sitting on each other or maybe screwed into each other. One cool Andromeda product that was available for a while in the mid-90's, had power supply, room for a few 5.25" and 3.5" drives (I think by default with hot-swap caddies... that may have been just added on though), and a Q-bus chassis all in a desktop small PC-clone style case. With just two cards (a Mentec CPU with 4MB memory and serial lines + an Andromeda SCSI controller + Ethernet, a tape drive, a floppy, and a couple hard drives) it was a neat, almost laptop-sized PDP-11 development environment. That came in really handy when I was traveling all the time. Tim.

Vintage Props for auction

by wmaddox＠pacbell.net

This one looks like it may have pieces of the front panels of early computer gear. Pretty dirty, but if I were in the area, I'd probably check it out and see what it is. http://www.sellauction.com/ga/EVENTS/GA073109/IMG/5069.jpg These look like they may be racks of real gear, rather than gutted-out facades, but who knows? Looks more like instrumentation than computer stuff. http://www.sellauction.com/ga/EVENTS/GA073109/IMG/5087.jpg http://www.sellauction.com/ga/EVENTS/GA073109/IMG/5088.jpg --Bill

Looking for early versions of Symbolics Genera (or other 'bolix software)

by derschjo＠mail.msu.edu

Anyone out there have versions of Genera prior to 8.1.1 they'd be willing to share? I've been playing with my 3630 and I thought it would be interesting to load older versions of Genera to play with. I'm also looking for other software to run on Symbolics machines -- I have the 8.3 distribution set from David Schmidt which includes Statice, Concordia, Joshua and DNA, as well as the S-Graphics package. Any good games? :) (Also: if anyone knows how to get a "new" ESDI disk up and running on one of these things, let me know... I'm guessing I need software I don't have to do so. I have a nice 760mb drive I'd like to put to use, but I can't find documentation on how to do anything other than a low-level format.) Thanks, Josh

I bring this up because of a few references I dug up on the internet that link Andromeda Systems with DEC-compatible gear. My guess is that this is an LSI-11 system, but it's just a guess. --Bill

PDP11/34a resurrection help

by jplist2008＠kiwigeek.com

Greetings all; I've had an 11/34a in the basement for some time now, but haven't ever had it "working", nor have I messed with it in several years - which, of course, means I've forgotten almost everything I ever knew about them, which is almost nothing, so I'm starting from scratch, pretty much. My 11/34a used to run a Xerox laser and came with a CDC9762, the card cage looks like this: AAAAAA BBBBBB CCCCCC DDDDDD EEEEEE FFFFFF 1 M8266 -------------------------------------------| 2 M8265 -------------------------------------------| 3 FLIPCHIP 4 M9301 YJ-----| M7856---------------------------| 5 National Semiconductor Memory Board--------------| 6 G7232---------| 7 G7232---------| 8 G7232---------| 9 M9202--------| G7232---------| 10 M9202--------| X031-| 11 X020 --------------------------------------------| 12 X030 --------------------------------------------| 13 M7843 -------------------------------------------| 14 FLIPCHIP 15 FLIPCHIP 16 FLIPCHIP 17 18 19 20 21 22 23 M9302--------| AAAAAA BBBBBB CCCCCC DDDDDD EEEEEE FFFFFF (Where slots 1-9 are in the right-hand backplane when looking from the front, and 10-23 are in the left-hand 14 slot backplane, which M9202 bridges between) I've got the DL11-W set up in the same manner as the 300bps example in the 11/34 Users Manual (and the DL11-W Operators Manual), and at this time I have the three X* cards as well as the M7843 card removed as I don't believe they're required for boot. I've verified on the backplane that +5 sits at a steady +5.06VDC and -15 is at -14.86VDC. I do not possess an o-scope, so the best I can do is with my multimeter. I have two problems. The first is that I do not own a "proper" cable that goes from the DL11-W to a terminal. I own a VT240 and have crafted a cable that goes from the Berg connector on the DL11-W through a header to a DB9, which connects to a DB25/DB9 expander on the back of the VT240. Obviously I've verified the VT240 is in 300/8O1 as required. To go from the flat-ribbon to the DB9 I have what used to be the header from a CDROM drive and have soldered the RX/TX/GND lines on the DB9 direct to the pins on this header. Currently it looks like this: BERG DB9 B 5 GND F 2 RX J 3 TX I -think- this is right, but I'm not positive. If I'm doing something stupid, I'd sure love to have someone point it out. Booting the 11/34a gives me nothing on console, but... Even if my cable works the 11/34a doesn't seem to be acting like it is supposed to. From my reading of the User Manual on power on, with the front switches set to CONT and the BOOT/INIT switch toggled to INIT and then let go, I should get the RUN light to blink out and then come back on and stay on. When I power on the unit the RUN light comes on momentarily, and then goes out. When I toggle BOOT/INIT the light flicks on, and again, goes out. I'm suspecting this means that somewhere the 11/34a is halting. If my console worked, perhaps I would get something to it - although, for all I know the console does work and the 11/34a is dying prior to it spitting something out. I would love any and all input as to how I should proceed. I'm reading as much as I can, but I've got a long way to go and help would be greatly appreciated. My thanks; - JP

Ibm 5160 xt

by rachael＠dahl-pind.dk

I have recently pulled my 5160 xt out of storage, but the powersupple seems to have given up on me, have anyone tried to repair one of those before. If its powered up with load the fan spins up , but there is a relay that is tricked on a small vertial installed print, turning the whole thing off. The case of the powersupple is big enough that I could put a new powersuple inside it with a bit for rewiring if it turns out to not be repairable. Regards Jacob Dahl Pind

New S-100 backplane and prototyping board PCBs

by lynchaj＠yahoo.com

Hi! ?I made this offer on vintage-computer.com and comp.os.cpm and thought there may be some home brew computer hobbyists on CCTALK that might also be interested. I'd like to offer more S-100 backplane and prototyping board PCBs using a new approach to get the cost down. ?My first batch of both S-100 PCBs are all sold out and the builders seem happy with them. ?My new idea is like a group buy to increase the order quantity and lower unit cost. ?I wrote up a description of the plan on vintage-computer.com here: http://www.vintage-computer.com/vcforum/showthread.php?t=16539 When I offered S-100 PCBs previously like the other N8VEM boards the unit costs came out at $25 for the prototyping board and $32 for the backplane. Both PCBs seem to work fine but I think the price was more than a lot of hobbyists were willing to pay. ?I can understand that so maybe this new method will work. For obvious reasons, I will not accept advance orders or payments in advance. This is a hobbyist project and non-commercial offering. ?My goal is to recover my own expenses of the PCB manufacturing order. ?I won't order a bunch of PCBs that no one wants and there is no point in proceeding if I am selling them at a loss. There are some on the waiting list already so maybe this will work. It really depends on how much participation there is which drives the order quantity up and unit cost down. As usual, constructive feedback is appreciated. ?Thanks and have nice day! Andrew Lynch

Altair 680 Memory Expansion Kits?

by billdeg＠degnanco.com

Thought I'd ask...I am looking for a new 4K (or more) RAM expansion kit with schematics for an Altair 680b that I can build myself. Ideally the kit would build an expansion card and operate like an old RAM card. An old vintage RAM card would be fine too, but that'd be expensive and I assume there are none to be found at this point save the rare luck. I am not sure if you can still get them from stockly.com. Thanks Bill

Xerox 860 IPS

by leaknoil＠comcast.net

I apologize in advance if you received this twice. I got an error message the first attempt and I am reposting it. I just picked up an old and neglected Xerox 860 IPS system. It came with a mess of spare boards, most marked bad, and a box of original Xerox disks. Problem is I can't get it to boot any of them. Is there someone on this list that could send me a known good one so, I have a place to start from ? I don't really care what it boots as long as it boots to something on yours. I've done all the customary re-seating of everything and swapping boards around but, the boot result is the same. Even with all the boards swapped out with spares. Everything is pretty clean inside. No leaking caps or frayed wires. Connectors all look good. I've read a couple entries on various pages claiming this was not really a computer but, a word processor that ran a custom OS. Mine came with original Xerox labeled CP/M disks along with COBOL, Visicalc, dBase, and Wordstar so, someone had to be using this as a more general purpose cp/m box. It also came with a Xerox Word Processing system disk that attempts to boot as well. It loads for awhile then just stops and does nothing further. The CP/M one boots for a bit then prints C to the screen like perhaps it is printing out the CP/M banner and dying after the letter C. the front display just read 0000 which I think means no errors. I have no idea if the keyboard works. Appreciate any thoughts. Thanks.

C64 sound problems

by dbetz＠xlisper.com

I just inherited a Commodore 64, 1541 disk drive, some joysticks and various other related stuff. I've tried the C64 and 1541 by attempting to boot a couple of games that came with the package and it seems that the computer and drive work okay. The games come up and display their start screen. My problem is that the sound doesn't seem to work. The games came up silent when I suspect that they have some sort of music associated with their start screens and a simple Basic program that I typed in to test the sound also fails to produce any output. I know that the SID chips in these machines are prone to failure but I was wondering if there were any other likely causes of a lack of sound. The main reason I was interested in this machine was to play around with the SID so it will be very disappointing to find that it is bad. Is there anything other than a dead SID that can cause sound problems on a C64? Thanks David

I'm afraid that's almost completely incorrect. It's true up to the late 1990s some time, but the result is an entirely misleading and inaccurate answer. The Mac VirtualPC product (released around 1997 or so) was ported to Windows and released in about 2001. It went through a couple of versions and was very well-received, partly as it was significantly cheaper than VMware Workstation and partly because it was simpler to set-up and use. Here's a review of it I wrote back in 2002: http://www.pcpro.co.uk/reviews/33972/connectix-virtual-pc-for-windows-5.html Because I was possibly the only journalist to ask Connectix about things like running Ring 0 code inside an emulator, which their press people were totally unequipped to answer, they flew Connectix founder and chief scientist Jon Garber over to London to talk with me and explain exactly how the product worked. VirtualPC was followed by VirtualServer, a server virtualisation product based on the same code, but with added support for features like direct control of a host SCSI adaptor by the OS in a VM. This aroused the interest of Microsoft, which was jealous of VMware's success, and Microsoft bought Connectix in about 2003. It discarded all the products except VirtualPC, which was maintained and sold for the Mac, VirtualPC for Windows, which is given away for free, and VirtualServer, which became the basis for the HyperV hypervisor in Windows Server 2008. However, HyperV requires Intel or AMD virtualisation instructions and no longer uses Connectix' software virtualisation. In 2002 or so Innotek GmbH ported VirtualPC 5 from Windows to OS/2: http://www.bityard.com/science-technology/Innotek/Connectix-Virtual-PC This is what the OP is looking for. There seems to be an eval version here: http://www.os2site.com/sw/apps/virtual/index.html Whether it's possible to use that & keep it running, I don't know. -- Liam Proven ?

Goodbye Compuserve

40 yrs of Lunar Lander - the other anniversary

by ragooman＠comcast.net

40 yrs of Lunar Lander - the other anniversary http://technologizer.com/2009/07/19/lunar-lander/ ?Lexington High School had a PDP-8,? Storer recalls. ?It had 8 Teletypes, a small hard drive, and 12KB of main memory, where 8KB was used by the system and 4KB time shared by the users.? Storer wrote his new program, ?Lunar Landing Game,? in FOCAL, a programming language for the PDP-8 that was similar in some ways to BASIC (both were introductory languages known for their ease of use). His simulation was simple, yet powerful: underneath lay a realistic set of equations Storer believes his father may have taught him. =Dan -- [ = http://www2.applegate.org/~ragooman/ ]

Lunar Lander source...

by wh.sudbrink＠verizon.net

Hi, Does anybody have a Z80 or 8080 source listing for a good raster graphic implementation of Lunar Lander? I'm going to be demoing my Cromemco loaded IMSAI at VCF East in September and while spacewar and tank war are fun, they require two players. I'd like a single player, relatively short (time wise) game and I think Lander is just what I'm after. Looking at my schedule, I'm not going to have time to write one from scratch but I should be able to port a good implementation to the Dazzler/D+7A. Tetris would be a second choice but a good player can tie up a tetris game for a long time. On a related note, does anybody have the source for Crush, Crumble and Chomp? Clearly, not for the show but I really enjoyed that game, back in the day. I had the PC BASIC source and I ported it to the Sanyo MBC550. I gave the Sanyo away before I started collecting and, as far as I can tell, CCC went with it. Thanks, Bill Sudbrink

Do not call them PCMCIA Cards (was "An interesting eBay find ....)

by Watzman＠neo.rr.com

The correct name for what you are [incorrectly] calling a "PCMCIA Card" is a "PC Card". PCMCIA is the name of the organization that owns the trademarks and they changed the name of the CARDS from "PCMCIA cards" to "PC Cards" more than a decade ago (early 1990's), but people just won't let go. The "MC" in PCMCIA stands for "Memory Card", which was [ALL] that they were when they came into existence, but that hasn't been the primary use of these cards in almost 20 years. And the "A" stands for "Association". Neither is appropriate to the cards themselves as they are used today, and "PCMCIA Card" is not in accord with the organization's registered trademarks [They own both the standard and the trademarks, they get to decide the "right" names for them.] PC Cards come in 3 mechanical form factors [thicknesses]: Type I, II and III PC cards also come in two electrical types (unrelated to type I, II or III]: 16-bit 32-bit (aka "Cardbus") A "Cardbus" card is still a PC Card. Note that, electrically, a 16-bit PC card is the laptop equivalent of an ISA card and a 32-bit (or "Cardbus") PC card is the laptop equivalent of a PCI card. You can put any function onto a PC card that a desktop slot of the corresponding type would have supported (and, conversely, you cannot, for example, create a 16-bit PC card USB adapter with USB ports; the necessary resources and data rates don't exist on the ISA bus, a PCI slot is required). 32-bit PC Card slots are generally backwards compatible to 16-bit cards. The reverse is not true. Laptops (and desktop card slots) changed from 16-bit to 32-bit in approximately 1997, about the time of the Pentium [one] 120 to 166 MHz class CPU.

Framemaker R5 for SunOS and more available

by dgriffi＠cs.csubak.edu

Do you remember some months ago Dave McGuire dug up ten copies of Framemaker for SunOS. He didn't want the rigamarole of packing up each of them, so I volunteered to do that. Today I just received a big box containing the packages. I picked up one, noticed the tape on the media box was already cut, so I took a look. On the CD, dated January 1996, I see this: ===begin-quote=== FrameMaker Release 5 UNIX Silicon Graphics Sun HP DEC Alpha IBM AIX FrameMaker FrameMaker, International Edition Frame Developer's Kit Frame Reader ===end-quote=== I mounted ths disc and, yes, it seems as though those other versions are there (including for Solaris and SunOS). Anyhow, Kelly Leavitt has already emailed me to claim one. The other nine are available first-come-first-served. If you want one (one per person), email me NOW. They're available for cost of shipping, which works out like this: $price_to_you = ($shipping_from_mcguire / 10 ) + $shipping_to_you + $price_of_carton $shipping_from_mcguire == $45 $shipping_to_you == $5 (media mail in the US) $price_of_carton == $2 This works out to $11.50 if you're in the US. A package weighs 6 pounds and 5 ounces or 2.9 kilos -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Consignment sales @ VCF East

by evan＠snarc.net

We're going to have consignment sales @ VCF East this year. In the past we didn't do much of that. Very simple rules: - Bring your on-topic things to sell. - Fill out form w/ description, asking price, lowest accepted price. - VCF keeps 15% of the final sale price (to the nearest whole dollar.) - Retrieve any unsold things at the end of the day (or end of show, your choice.) Show is Sept. 12-13 in Wall, New Jersey. More details (speakers, exhibitors) frequently updated at http://www.vintage.org/2009/east/

looking for ASR43 tech docs

by ronan.scaife＠dcu.ie

Dear all, 1. my several attempts to subscribe to this list have failed; can anyone help? 2. I bought the ASR43 paper tape attachment for a Teletype Model 43 on Ebay last month. As the punch advance does not seem to work, I need to gain access to any relevant technical documents that may be available. I have done an exhaustive search. I am prepared to pay a reasonable amount for a scanned pdf (or even paper) copy of service or assembly drawings or schematics. I am located in Dublin, Ireland. Best Wishes, --

So are photocopiers of a certain brand Xeroxen? Are helmsmen coxen? If I receive one fax then another are they faxen? If I apply one fix to my program and then another are they fixen? How about a dog fox and a vixen, are they foxen? One mix plus another are mixen? Small pox and chicken pox are poxen? One sax plus another saxen? Male and female sexen? Do your pay your taxes or your taxen? Surely in 90% of cases the norm is to add es. Adding en sometimes makes a noun in to an adjective, flaxen, waxen for example. Apart form oxen (a.k.a. bullocks), I could not think of one other example of plural xen. There may well be more but it was quite easy to come up my list which should all be xes.

seeking documentation for the LC8-P M8365 LA180 Printer Control card for the PDP-8

by nigel.d.williams＠gmail.com

I am hoping to get a PDP-8/E soon so I grabbed the LC8-P off eBay with the idea it might provide an easy way to get a simple I/O capability for the PDP-8. I expect it could be quite similar to the LC8-E but it would help to have the schematic and description to be sure. thanks, nigel.

TK50 tribulations

by steve＠cosam.org

Hi all, I recently dug out a TK50 I was tinkering with before and am having some trouble diagnosing what's up with it. It arrived with a tape stuck in it, but I've since managed to persuade that out and a good clean up had it loading and ejecting properly. Now any read or write just results in a bit of shoeshining, whereafter it goes into its light-show routine. Yes, I should probably just admit defeat and keep it for parts, but it seems so close to working I thought I'd take another stab. The technical manual lists all manner of error codes which should narrow things down. I'm however at a loss as to how one should extract them from the drive/controller. I've had it hooked up to a PDP-11 and XXDP said nothing more than that the drive was faulty. I also have a MicroVAX II (where it actually came from) but I've not been able to run diagnostics on there due to lack of a floppy drive. I did experiment with an RX33, some RX50 images and a PC to write them, but the MicroVAX doesn't want to boot them. Any ideas? Cheers, -- Steve Maddison http://www.cosam.org/

Write-only backup media and big archives

by mailman＠trailing-edge.com

Not really a mechanical or procedural thing, but a little more philosophical as I think about data storage not just at home for classic computing, but at work: In the 90's the CD-R and soon after the DVD-R looked pretty ideal for making "write only" backups of what was then considered large amounts of data. While not archival in the centuries sense, it seemed a pretty safe bet that readers would be readily available for the next 10 or 20 years and I think this bet has turned out well. I was willing to spend an afternoon buring a dozen or two CD-R's because they felt "real". But today, a "large amount of data" is not a few gigabytes, but terabytes. Tape libraries with these sorts of capacities do exist but aren't available at the corner store and I have a nagging mistrust of tapes that causes me to refer to them as "write only memory". (I never really ever trusted anything denser than 1600BPI 9-track!). Burning 2000 CD-R's or even 500 DVD-R's doesn't seem like a reasonable or useful task to backup a terabyte hard drive (which today is a fraction the price of the 9 Gig drives of the mid-90's that was "big storage".) At the same time, the ubiquitous and available-at-the-corner-store terabyte-sized USB drives don't feel awfully reliable either. They are way more convenient and cheap though, and that's my prefered backup media today. I think I'm falling into the trap of confusing the price of storage with the value of the information recorded onto the storage. It's ironic that as disk space has become cheaper and cheaper, we regard the contents as less worthy of the effort of backup onto reliable media. OK, philosophy mode off. The NTSB is gonna be asking me for a few gigabytes of data next week and that seems easy compared to the terabytes at home. Tim.

Keeping in mind that if you do not unstick the heads the drive is junk. So if you break something nothing lost. Take a moment to do careful inspection of how this are put together. Cleanliness, do avoid getting dust, fingerprints, dandruf, lint on the media. Take reasonable care to not introduce loose foreign matter. To that end cover drive with it's cover when not actually working inside or between work sessions. With that apply force as required to unstick them and (with media is rotating). So not apply force to the end near the heads, that part is fragile but closer to the pivot assembly where there is some structure. Once you have gotten them free you need to deal with the failed polymer that is now goo. In the past I've used a dental pick to remove it and I've also use a bit of paper that nicely adhered to it to prevent head sticking. Basically the head return bumpers are there to soften and quiet the return of the heads to the rest position on power off decompose and get sticky. Those that have used TU58 and other cartridge tape drives know the "roller turned to goo" problem, same material. Allison >Thanks > >Rob

9-track BOT/EOT markers?

by derschjo＠msu.edu

Hey all -- Got myself an HP 7980S 9-track drive (always wanted a 9-track drive...) and accidentally mangled my one and only 9-track tape just after the BOT marker (not sure what caused it, maybe the drive needs a bit of adjustment...). So I have two questions: Where can I find a reasonable replacement for the marker, and where does it go? I see the sense foil on the part of the tape that got mangled, but I don't know what side of the tape it was originally on... Thanks! Josh P.S. The magical tape autoloading thing this drive does is the coolest thing I've seen in a long time :).

Just worked out the interlock mechanism that was stopping the heads moving much, I can move them as much as I like now, but I am still unclear where the goo that is causing them to stick is located and how to reach it.

logic probe cases

by dgriffi＠cs.csubak.edu

In case you're seeing mysterious requests for money, that's me getting the logic probe case group buy going. When everyone who's put their name in has paid, I'll make the order. If you decided you want more or less, pay your invoice accordingly and drop me a note saying what you want me to do. The price is $4 per case and $5 shipping. Steve Maddison is the only non-US taker I counted. Please correct me if I goofed. If you didn't say so earlier and now want one or more cases, let me know and I'll invoice you. The door closes when I hear from all the takers (within reason). -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Micropolis 1015-2 floppy drive

by dm561＠torfree.net

-----------Original Message: Date: Wed, 15 Jul 2009 10:02:24 -0500 From: Chris Elmquist <chrise at pobox.com> Subject: Micropolis 1015-2 floppy drive Does anyone have specs or even better original documents for a Micropolis 1015-2 (aka mod II) 5.25" floppy drive? I have two connected to a Micropolis designed floppy controller in an old S-100 system. My memory tells me these were single sided, double density, 77 track, 100 tpi drives. But I may be confusing them with other Micropolis models that were used in this particular S-100 system around the same time. The S-100 system was built by Multi-Tech Systems Inc (the modem guys) here in St. Paul, MN around 1980,81. It is a model MT-500 and is a clone of an R2E design that came to market around the same time. I wrote portions of the PROM and CP/M BIOS for this thing when I was in highschool. I, of course, saved many pieces of the things and am preparing to bring one of them back online soon. Chris -- Chris Elmquist ---------Reply: Your memory's pretty good; they are indeed SS/DD 100TPI; there's also a 1016-2 which looks like pretty well the same drive. Vector Graphic used these drives with a Micropolis controller; I have two VG systems that use them (with hard sector disks, FWIW). The bare mechs were also used in Commodore 8050 dual disk drives (as well as Tandon and MPI) but with custom electronics. You can find a maintenance manual (26MB) at: www.vector-archive.org in the VG Docs CD folder. The Micropolis controller manual is in the Manuals folder.

YE-380 floppy schematics

by rcini＠optonline.net

All: I?m troubleshooting my IMSAI that has YE-380 high-density 5.25? floppy drives replacing 8? drives, and I?m looking for schematics of the drive. The YE-380 drives were originally used in the IBM PC/AT, but I?m sure other machines used them too. I did some googling earlier and didn?t come up with anything useful. Does anyone have a pointer to the schematics or a pdf/jpg you could send me? Thanks!

When the drive is powered down there is a magnetic retract and at the end of travel there are bumpers that betwen heat and time get sticky. The windup then down is the failure of the heads to move and find servo and it fails. There are two fixes, temprorary is to freeze the drive and sometimes they unstick. Me I open the drive, unstick the heads and reach in to the mech and pull out the goo they stick too. Never had a failure yet and all 6 of my RD53s are salvaged this way and most were opened over 10 years ago (two approaching 15!) and they are well past their MTBF now. I haven't opened any in years since I haven't found more and generally RD53s are more useful to me as spares, swap or for the Qbus pdp 11s I have. Other than that goo problem they were otherwise reliable drives. I also have a boat load of RZ22,23,25, RZ55 and RZ56s in use and a pile of RD52s (quantumn D540s). The RD52s are only 31mb but perfect for swap or RT-11 based systems as they were very fast for their storage size and unkillable. I have better than 12 of the D540s as I use them in CP/M based systems as well. For backup I use the RZxx as backup as they are faster and more reliable than TK50. TO create a new system I do a backup/image to a same size or larger to clone the disk and system. Same for the MFM drives. Old 1gb SCSI Baracuda drives are excellent for MV3100s and anything with SCSI and the run forever. If you going to mess with MFM drives you must have a MicroVAX2000 as its a good RDxx formatter in a box (RqDX3 compatable). If it has decent amount of memory and an RD54 in it they can be fun to play with as they are small and very portable. The alternate is to MOP load VMS to it and use a small 20-40mb disk for local files and swap. With two you can run LAVC! Allison

A better question might be why are you running V5.4?

TMI (was RE: Do not call them PCMCIA Cards (was "An interesting eBay find ....))

An interesting ebay find and what to do with scsi do-dads

by brianlanning＠gmail.com

I picked up an external scsi case with 5 devices in it. Two plextor cdroms, a zip 250 drive, and most interestingly a 3.5" floppy drive and some sort of memory card reader. This furthers my collection of internal and external almost-useless removable media devices. :-) It was sold as an IBM branded device, although I knew before hand that it wasn't. But there is an IBM sticker on the back of the case that says M/T 1609-F21 and a serial number. Not sure what's up with that. Maybe it's just an asset tag. So what could I attach this to? It has one centronics port on the back, so it must be terminated inside somewhere. I know the cdroms and zip drive would be recognized instantly by an amiga. I'm not sure what the floppy and memory card reader would look like. For example, supposing it's a 1.44mb floppy drive, what format would an amiga try to write to a drive like this? I would think that a disk format is OS dependent. I do have drivers to read fat partitions, so maybe it could read PC floppies. Or maybe since it's high density, it could read/write those 1.76mb amiga format high density floppies... or maybe not since it's scsi and the amiga specific floppy drives tend to be modified in an amiga-only way. I couldn't tell what kind of floppy drive is in there since I didn't completely take it apart, but from the back, it looks like a normal 3.5" floppy drive in a 5.25" scsi 50-pin adapter. Linux would probably autodetect and work with all of them. What would MacOS do? Also, the memory card reader has a slot for a type 1 or 2 pcmcia card. What could I put in this? A pcmcia flash memory drive seems obvious. What else? brian

Cleaning an LK201 Keyboard

by jhfinedp3k＠compsys.to

I just cleaned an LK201 keyboard. It was actually quite clean with only a few stains and a bit of dust. I used a baby wipe since it seemed to be the most useful in terms of being able to eliminate the dust as well as the very minor stains. Has anyone any other method or suggestions? One problem is that there is one sticky key - PF4 in this case. It is not a problem if I use a quick sharp hit of 4 to 5 times the normal force. When just a gentle to firm force is used, it often sticks and sometimes even goes into multiple repeats. Hitting it firmly again frees up the key and it releases. The problem might have been caused during the cleaning if some of the baby wipe is stuck within the key release mechanism - I tend to remember that the PF4 key was not sticking when I tested it before cleaning. Any suggestions? Jerome Fine

Classic mac fun (and some questions) (continued...again...)

by brianlanning＠gmail.com

I have but one obstacle left... being able to unpack an apple floppy image file from a PC. I have a bin file containing the files I need to get the quadra going. I got the floppy drive working on the quadra. I can read and write mac floppies from my windows machine. But I can't get the files out of the bin file. And I can't write the bin file directly to the disk and make the quadra read it. So i need either a mac emulator I can run on XP, or a windows utility to unpack the mac bin file and produce individual files which I can write to the floppy. Anyone have any ideas? I also picked up a rare and elusive kung-fu black terminator for the IIfx. So I should be able to attach the 600e to that machine and get it going. That hard drive would hopefully be recognized by the install CD. Then I would only need to find an AUI to RJ-45 doodad which is skinny enough to fit into the recessed ports on the IIfx. I have an AUI thingy now, but it's too fat to reach the db-15 connector on the network card. brian

IBM 5150 PC

by sethm＠loomcom.com

I just picked up my first 5150. It's a later 1983 model, in pretty stellar condition, with a single top/bottom half-height 5 1/4" occupying the left full-height bay. I'd love to add a Winchester disk, but I understand that the early PCs did not have a power supply capable of driving a Winchester. How can I tell which power supply I have? My Google-fu has failed me on this query. Unfortunately it's not sitting in front of me at the moment, so I can't read any part numbers off of it; I'll have a look later tonight, but I recall it being a 65W power supply. -Seth

Anyone have a valid address for Jim Willing?

by ethan.dicks＠gmail.com

Hi, all, I was searching Google Images for pictures of the blank filler panel brackets (the discussion earlier this week) and ran across an image on Jim's site of a "CompuServe Node Board". I know a little bit about them (perhaps not as much as some on this list) and wanted to pass some info to him from my own experiences (I happen to have a tri-node chassis, but no CompuServe-made boards). My attempts to write him directly bounced. Basically, I wanted to tell him, yes, they are Qbus boards, yes, they are longer than standard DEC boards (longer than "extended length"), and at some point prior to 2003, they made 486-based Qbus boards and must have ported their PDP-11-based network transport software to Intel. Does anyone know what types of boards CompuServe might have made for the "newer" nodes (besides serial boards and Intel CPU boards)? Thanks, -ethan

Micropolis 1015-2 floppy drive

by chrise＠pobox.com

Does anyone have specs or even better original documents for a Micropolis 1015-2 (aka mod II) 5.25" floppy drive? I have two connected to a Micropolis designed floppy controller in an old S-100 system. My memory tells me these were single sided, double density, 77 track, 100 tpi drives. But I may be confusing them with other Micropolis models that were used in this particular S-100 system around the same time. The S-100 system was built by Multi-Tech Systems Inc (the modem guys) here in St. Paul, MN around 1980,81. It is a model MT-500 and is a clone of an R2E design that came to market around the same time. I wrote portions of the PROM and CP/M BIOS for this thing when I was in highschool. I, of course, saved many pieces of the things and am preparing to bring one of them back online soon. Chris -- Chris Elmquist

by roger.holmes＠microspot.co.uk

Didn't there used to be a problem with 3D printed parts going brittle and breaking when subjected to UV light, like sunlight or fluorescent lamp light? What the world really wants is a 3D printer to print 3D integrated circuits, including cooling ducts -either for cooling fluid or alternatively for (heat) conductive material like copper, or both. Can silicon and other constituents of ICs be accurately sprayed under computer control?

Oddball RP02 / Memorex 660 question - sticky paint

by mross666＠hotmail.com

On cleaning up my RP02, I find that the 'basin' - the sheet metal which lines the cavity in which the disk pack spins - is painted with a dark grey paint which is positively sticky - tacky to the touch. I've never encountered this on a disk drive before. Do people think this is just old, deteriorated paint? Or is it possible that it's intended to be sticky - to trap any particulates which elude the HEPA filter? If so, would that have been factory applied, or a customer 'modification' done in the field? Anyone ever found sticky paint on a removable-pack disk drive before?

can anyone help with a visual 1050 rom dump

by d_cymbal＠hotmail.com

Hi All, I have been working with the folks over at the mess project (http://www.mess.org/) on an emulator for the Visual 1050. It's coming along really well. One thing we are lacking is a rom dump for the keyboard. There is either an 8039 or 8049 in the kb with associated firmware we would like to get a dump of. Also, it would be great if we could collect other versions of the Z80 and 6502 firmware. We currently have dumps rev'd at 1.2 (Z80) and 1.1 (6502). It would be great to get dumps of any other versions. If anybody can help out could you please contact me? Thanks.

MicroVAX 3800 won't boot from hard drive

by wverish＠aol.com

My MicroVAX went from booting from DUA0 one day to acting as though the drive does not exist the next.Error code is:?41 DEVASSIGN, DUA0 ?06 HLT INST ?PC = 00000C1A. ? The tape unit seems to be OK, but I don't have a bootable tape to try it with. ?I bought another KFQSA board hoping it would help but it did not. The two drives seem to be spinning, but I don't know their condition. I hope you will take the time to think about what might be wrong. I have been working with Dan Snyder in PA, and he said to try e-mailing your group. Thanking you in advance, Wayne Verish

RSTS-11 distribution?

by Barry.Moyer＠pason.com

I would be most grateful for any RSTS-11 version V4 or earlier. The RSTSV4A disk at rsts.org does work, but I am after a distribution to construct an equivalent. I have located tape image files that should contain the distribution, but the tapes are not directly bootable, and I don't know how to get them to play nice with E11 or simh (I have tried both). Once I get a prepared Rk05 disk under the simulators, I can get the disk image onto the real disk. As I mentioned, I want to learn the black art of running my old machine using the distributions that were from the same era (1970 - 1974). Thanks! On Mon Jul 13 10:15:52 CDT 2009, Zane H.

IIRC, basically you open the drive up and remove the sticky rubber pads. I really don't remember the details as I went SCSI nearly 10 years ago. Zane

Thanks for asking though :-) I take it that this means you're backing up a MicroVAX II via DECnet to VMS running under SIMH? Or that you simply have copies of everything on a SIMH virtual disk? I'm asking as the RD53's are hidiously unreliable. Never count on it powering back up after you power it down. I would have a copy of a nice VAX/VMS v4.x system disk if I'd had everything setup and done a backup the first time I powered it up. So I'm speaking >from personal experience. :-( Zane

RSTS-11 distribution?

by iamvirtual＠gmail.com

I am looking for RSTS-11 circa 1972 to install on my PDP-11/10 machine. I am more interested in a "historically correct" rather than "more useable" system. I have a PDP-11/10 with 32kw core memory and an RK05 disk drive. My goal is to load RSTS-11 on this machine. I have scoured the internet, including rsts.org and Bitsavers, but I have not come up with an installable distribution. My plan is to use Ersatz-11 or simh to prep a virtual RK05 disk. When I am happy with the setup, I will transfer the binary disk image to my real RK05. I wrote a program that allows a binary disk image to be transferred via a serial port (I will release the source once I am successful in getting the machine running). My hope is that I can find a distribution (virtual tape, virtual disk, etc.) that I can use to install my OS. I am looking to learn and understanding the process so that I can become self-sufficient. Any ideas where to begin? --barrym
