Long shot: Looking for Truvision NuVista-HR nubus card

by derschjo＠msu.edu

I'd like to play around with the Color systems on my MacIvory, which requires either a NuVista or NuVista-HR video card. The Nuvista card is limited to very low resolutions (it's geared to PAL/NTSC output), so I'm looking for a NuVista-HR, which does much higher resolutions. The NuVista card shows up on eBay all the time, but I haven't yet run across the -HR variant. Anyone out there have one to part with? Thanks once again... Josh

Symbolics XL1200 for sale

by spc＠conman.org

Found the following page: http://accordionguy.blogware.com/blog/_archives/2007/1/27/2687720.html Wherein Joey deVilla is selling a Symbolics XL1200. All the details are in the link, but some overview: The machine has a hardware fault that prevents it from fully booting, but it does display said diagnostic message. The machine itself is in Toronto. I'm not sure if it's sold yet or not, as the message was put up on Saturday (and I'm just noticing it now). I'm not involved with this in any way, other than just passing on the information. I've bought some books from him before (and he's got a ton of books for sale as well) with no complaints. -spc (He also goes into the story of why he's selling the unit, which is amusing ... )

Re-Introducing the First, and Fully Functional, Lisa Emulator

by ray＠arachelian.com

On January 24th, 1984, the Macintosh announced, but along with that announcement came another that not everyone recalls: The introduction of the Lisa 2. Reflecting the echoes of that date, I'm announcing the availability of The Apple Lisa Emulator. While there are still some flaws and missing features, to address, I've decided that it was more important to honor the Lisa's January introduction. You'll be able to download the emulator from here in a few minutes: http://lisaem.sunder.net/downloads.html Questions about the emulator should be directed here: lisaem at sunder.net Bug reports here: lisaem-bugs at sunder.net To use the emulator you will need a copy of the Lisa Boot ROM (preferably version H) as well as OS software. Please do not ask me to provide these. If you own a Lisa, you already have legal copies of these. The emulator currently runs on the following platforms: * Mac OS X - Intel and G4 PPC. * Linux - since there are too many distros, I'm releasing a statically linked X11 binary for 2.6 kernels, which should run on most distros, but you'll probably want to compile your own version instead. * win32 (w2k and possibly XP) The project will also compile and run wherever wxWidgets runs on a unix like platform (with some tweaks), I'll put up more binaries as time permits. Source code will be released in about a week or two, licensed under the terms of the GNU Public License 2.0. There are parts whose quality of the code isn't as good as I'd want it to be. :-) Known bugs: No documentation, at this time there are hooks in the help menu that point to the website, where I'll fill in documentation. Future releases will have built in docs. The raw keyboard routines aren't quite right. Use the ASCII kb mode for now. Won't run Xenix - it boots but stops before the shell, likely a VIA bug. Printing works, but isn't yet completed (spits out ugly postscript files only at this time, needs wxWidgets integration which I'm currently working on) Win32 LibDC42 routines might not be too stable, may cause trouble with Profiles Sound isn't perfect, although it does beep on most platforms, the "click" is treated incorrectly as a beep. Some of the animation has color issues in some of the BMP's/XPM's - i.e. floppy insertion Mouse movement under certain environments isn't quite right (I've optimized for Lisa Office System.) When the emulator quits, on OS X, it segfaults (crashes.) Won't work with Lisa 1 ROMs as there is little support for Lisa 1 HW emulation at this time. A few tools I intended to write still need to be written. Why a Lisa emulator? There are many reasons to this project, and even more for the decisions that shaped it. The most important goal was to preserve the technology behind the Lisa, and allow future generations to experience a piece of history. If you search the web, you will find lots of articles, pictures, and even videos of Lisa's. But these are second hand information, in that they do not allow you to actually interact with an actual Lisa. Unfortunately it isn't possible to fully emulate the physical aspects of a computer. You cannot experience the almost imperceptible 60Hz flicker of the display, the not-quite paper white, blueish tints of the phosphor, the yellow glow of the power switch, the heat a Lisa computer gives off, nor the feel of its keyboard, mouse, or see the curvature of the CRT on modern LCD and flat CRT displays. But, you can still get close. I hope that long after the last functional Lisa is gone from the face of the earth, that my emulator, as well as the documents that David has collected, would survive and allow future generations to go back in time and experience what it was like, to study it, and understand how and why it was built. In many ways, as I watched Lisa Office System and MacWorks boot up (via trace logs), I saw many glimpses into the software design ideals and practices of the early 80's. I've never been an archaeologist, and don't really know that experience, I can guess at the rush and thrill of discovery. Seeing the machine code of various Lisa OS's fly by has been that experience for me. I could almost understand what the coders that wrote them were thinking, how they designed things, and why. I could easily tell what code was hand written assembly by an expert, or novice, what assembly was generated by compilers. I don't much expect many to spend more than a few hours with the emulator, but perhaps there will be a few like minded folks who remember the Lisa and want more than a stroll down memory lane, or want to learn what it was about and how it worked who will. By releasing this as GPL, I'm guaranteeing its future long after I would loose interest in maintaining it. There are many emulators that are closed source, or shareware, or that are outright sold, and thus locked down. These are less likely to survive the ravages of time, and thus are less valuable in the long view. While I cannot presume that the libraries and API's upon which this emulator was built will still exist, I can at least hope that it will be relatively easy to rewrite or port to future platforms. I purposefully built the emulator on what some would consider exotic hardware. (i.e. DEC Alpha) to force me to write portable code. At various times, I also had it running on the SPARC, PowerPC and Intel chips. (i.e. a range of 32 and 64 bit CPU's with different designs.) Although I cannot vouch for it running on SPARC or Alpha at this moment in time, by building it on varied platforms, I avoided locking myself into a particular CPU with specific endian issues, and thus exposed more bugs. While I've only compiled the emulator under variations of GCC >from 2.x to 4.x, I suspect that it will work with other compilers after some tweaking. There is some history to this emulator. A synopsis for those who aren't yet bored of reading this rant: This project started in February 1998, when one day I attempted to power on one of my two Lisa's, and it no longer turned on. I realized that as with all retro computers, that replacement parts would over time become scarce to obtain and that repairs would be more and more difficult. In the interest of preserving the historical significance of these machines, I thought that an emulator would be one way to preserve them. Having been inspired by projects of the time such as Executor and vMac, I naively assumed that this would be an easy project, taking only perhaps a year or two. The Lisa is a far more complex creature than I imagined. Luckily, I managed to find David Craig's contact information, and obtained a ton of Lisa documentation from him. Most of the Lisa documentation out there on the web exists because David had carefully collected and cataloged it over the years. Without his efforts, neither this emulator, nor any of the spin off emulators would been possible. I would also say that without his efforts a great deal of Apple history would have been lost to the ravages of time. Perhaps a large portion of the remaining Lisas would not be repairable without this type of information information. (This is why I've spent a lot of time distilling David's documentation and the knowledge of LisaList in building the LisaFAQ.) While I was, at best familiar with the C language, and knew some 68000 assembly, there were a lot of things that I had to teach myself. I've learned a lot more than I could possibly list here (C, Unix programming, Xwindows, wxWidgets, deep 68000 coding techniques, low level operating system stuff, postscript, PCL, anti-aliasing, reverse engineering, optimization techniques, and so on.) So there was great benefit to me beyond the emulator itself. There were many wrong turns taken throughout the lifetime of the project. Most notably, I originally wrote my own 68000 CPU core, but scrapped after the generator ( http://squish.net/generator ) core was recommended by Richard Bannister. I originally wrote the emulator directly for the XWindow System. Yes, that's right, raw xlib calls without a toolkit. Writing your own UI in XLib is quite the exercise in masochism. I didn't replace the xlib UI with wxWidgets until late 2006. (In 1998, Motif was the main toolkit out there, but as it was commercial, and since Tk was sort of obsolete, with not too much else was available, or portable to all platforms. Xlib seemed to be the right choice. Over time, I stuck with xlib because I didn't care as much about the UI as much as getting the emulator working.) I must have rewritten the MMU subsystem at least three times. In hind sight, I probably over-engineered the last iteration in an effort to cache the MMU tables, but it works very well. I probably have spent too much time on sysadmin duties (that is setting up environments for myself to develop in.) After all, system administration is my day job. This project was originally born on a DEC Alpha Multia running on OpenBSD 2.3 or such. I moved it to an old SPARC running Solaris 2.5.1, then a sparcbook running 2.6, then Cygwin under w2k, then coLinux under w2k. I now have it running under Ubuntu, coLinux, win32 and OS X. As I'm told, there was talk of a Lisa emulator before 1998, but no actual project had been started. I released my crufty 0.00 version of the source code back in 98, hence "The World's First" is accurate enough. As far as I know, this is the only Lisa emulator that is capable of running the Lisa Office System, hence "fully functional." (Some would argue this because it doesn't yet run Xenix, but that's less important to me.) Of course, all of the documentation I had scanned, and put online attracted others who wanted to build their own emulators. Unsurprisingly, they did have some success, but not with Lisa Office System. I was disappointed with the competing project, but kept quietly on working on my own throughout the years. I hid my actual progress since the emulator wasn't working yet, and besides, it would have only fed the competition valuable information. I thought he had the advantage, since he had the whole of the MESS team and library of code for various devices, while I was writing and rewriting nearly everything from scratch. It surprises me to this day that despite all of my perceived fumbling, that he hasn't overtaken me yet! (I suspect that in a few days, or perhaps weeks, - i.e. sometime after I release my sources, we'll see the other two competing projects gain the capability of running LOS as well.) I intentionally let the website look dead to give the impression of abandonment, while I redoubled my efforts. This became a fun cloak and dagger kind of game: I only decloaked once, when I though that I was very very close. One day in May of 2006, I found the secret magic to make the MMU work. I got the Lisa Office install disk to boot, and everything started falling into place. I then furiously debugged the VIA code, and then the ProFile code, and it started to all work. The SCC came next, along with other fun stuff. I rewrote the imagewriter code twice over. (Once again, this week, for wxWidgets printing/output, which isn't in today's release.) Towards the end of 2006, I purchased the wxWidgets book and reworked the UI. It'll probably be a few more months before the emulator would be perfect in my opinion but that would miss the January 19th announcement anniversary, so early, buggy, release it'll have to be. :-) I would like to thank the following folks for their numerous contributions: David T. Craig for the wealth of Lisa information which he allowed me to scan in, for the many contacts with Lisa developers and faithfully listening to status reports over the ages, James MacPhail for all of the hardware help with the Lisa and many suggestions as to what and how to test, for helping me with the logic analyzer, for the 68000 help, for the schematics help, for helping me repair my dead Lisa, for the help with the ProFile protocol, and many other things I could fill a book with. James Ponder for his wonderful Generator project, one of the better Sega Genesis emulators out there, whose CPU core is the heart of the LisaEm project. Adam Firester for providing the many years of bandwidth for the project website, Steve Hatle for providing Lisa Office documentation, Xenix help, encouragement, and beta testing, Brian Foley for beta testing, profiling, and debugging help with OS X, and fixing nasty display bugs in wxWidgets on OS X, Chris McFall for advice on the Lisa file system, Natalia Portillo whose file system work inspired me to build the Lisa FSH Tool, and later libdc42, Patrick Schaefer for providing the protocol transitions graphs of the Profile, which at a glance proved far clearer to interpret than the official documentation, Andy Hertzfeld for his amazing folklore.org website for the numerous fun stories about the birth of the Lisa and the Mac, The wxWidgets folks, whose project I wish I made use of a lot earlier, who have made my life a lot easier, especially Stefan Csomor who found an early bug in my display routines, Steven Stengel of http://oldcomputers.net for the Lisa image used as the icon in the Mac OS X version. Raphael Nabet, for disassembling and documenting the I/O ROM, which shaved about a month off of reverse engineering on my part, even if he did write a competing emulator. :-) Gilles Fetis for being the third person to use my dc42 routines. :-) (Gilles, If you thought those were cool, wait till you see libdc42!) To all of the folks who have wished for a Lisa emulator, whose requests and encouragement over the years pushed me to complete this project. Most importantly, to all of the people at Apple, who worked on the Lisa over the years, and remember it fondly. Lisa, Lisa Office System, and the Macintosh were trademarks of Apple Computer, Inc, now Apple, Inc. w2k/XP are Microsoft's trademarks, etc. Genesis is trademark of Sega, etc.

VCF East 4.0 update -- Commodore Pet 30th bday party w/ Chuck Peddle

by evan＠snarc.net

Hi all, Today, Sellam and I confirmed Chuck Peddle as the keynote speaker for VCF East 4.0. There will be other notable early Commodore computer people as well. Just as VCF 9.0 celebrated the 30th anniversary of Apple, at East 4.0 we'll do Commodore! The show is Saturday, June 9, starting at 9:30am. The Commodore panel will be from 10:30-12 followed by Chuck et al signing autographs. We still might expand the show to Sunday, June 10 as well. To be determined. Of course there will be plenty of other cool things and people beside Peddle. For example, we found a guy who worked closely with John Mauchly, and he might be a speaker for us. Talk about being one degree removed from history! - Evan

Looking for UK ESDI drive >= 300Mb

by andy.piercy＠gmail.com

Folks, Does anyone have a spare 5.25" full height ESDI drive >= 300Mb in the UK that they are willing to part with. All the drives on Ebay are in the USA and the cost of shipping and the chance of the drive making it in one piece would be prohibitive. An old Sun drive like "327M Micropolis ESDI drive 370-1133" would be great. Please contact me off list if you have anything available. Thanks, Andy.

Machines I posted as avail last night.

by dave06a＠dunfield.com

I guess I should have been more clear - by "details", I ment details on the machines availability - ie: I will put you in contact with the owner. These are machines that have been offered to me recently, but are too far away and not worth shipping for me to acquire them - I don't know anything more about them than the model information I put in the subject line of the original message - I don't know how big they are, or if they work, or what material comes with them (so please stop asking). So far the machines I posted were: Compaq Portable III available in Brewerton NY, USA Televideo CPM machine available in Canberra Australia NEC APC H03 available in Rhode Island, USA I believe all of them were described as "working when put away years ago" - I know nothing more. I will collect the responses for the next couple of days, and then forward them to the current owners of these machines.

need insights on finding big cartons

by SUPRDAVE＠aol.com

If you happen to work in or near any manufacturing facility, get friendly with the person who runs shipping/recieving. All kinds of good packing material gets thrown out daily. At my previous job, I I had access to all the used boxes and packing material I could ever want. The plastic air pillows work good for filling up empty space, and the crimped brown paper that's used is great for padding and seperating items. Most boxes containing computer equipment is double thickness and worth searching out. Amazingly, shipping material is very expensive! Another place to look is near construction areas of strip malls and such. I scored some very large flat cardboard and some large hard foam blocks from behind a fitness center that was opening up. An old nonserrated steak knife cuts hard foam with a minimum of crumbs.

Bob, Wanted to let you know that once I knew which address the package went to, I was able to track it down. Thanks for looking that up for me. I just need to order some 10 LED bars and I can get the Panda lights put together. I'll probably have enough stuff for a parts order within the next few weeks (thinking of a DigiKey order for some Atmel processors anyway). Cheers, -ethan

SGI Challenge XLs up for grabs

by pat＠computer-refuge.org

I have two SGI Challenge XL racks going up for grabs; I really need the space back for other new equipment. Make an offer, mostly just want the space back, and I don't really have a use for another big old Irix box.. One is an R10k system and one is an R4400 system. I don't remember exactly how much memory and procs are in each, but could go look. They both have 10BT ethernet and FDDI connections. Pick-up is preferred, from Lafayette, IN. Zip 47901. If you want me to ship the machine, expect to pay for my time and effort to do so, in addition to freight charges. If I don't get a response by Feb 3rd, I'll be parting the machines out to sell on ebay.

I > would have thought that the boot ROM code would have to know about > the CD without the aid of an extension... First of all is the CD bootable? You might want to load the CD and then look in the startup disk control panel and see if you see the CD as a boot disk - this is independent . If so, choose it and restart - the older systems only boot from the disk designated in the control panel. The 540c existed from May 1994 to August 1995 - almost exactly the same era as the 150 so the CD 600e should work. >>> 3.

IIRC Stuffit expander was include on both the 7.5 and 8 installs. Do a "find" to see if you have it on Alternates: if you have the dark gray SCSI adaptor cable, you can hook the laptop up as a disk to another Mac's SCSI system. The "PowerBook Setup" control panel allows you to choose the ID. Also, if you have an AAUI you can drop the laptop on your LAN and transfer files that way. CRC

RS366

by ard＠p850ug1.demon.co.uk

A bit of background : Spread over my bench at the moment are the insides of an HP11284 Data Communication Interface for the HP9830. This is a somewhat nice-for-the-time unit that does async and sync protocols, etc.. Anyway, as well as the RS232 interface to a modem, it also has an 'RS366' interface to an ACU (Automatic Calling Unit?). From what I've managed to discover so far, this is an interface for autodialers, it uses a DB25 connector, 'RS232' voltage levels (in fact the HP11284 uses 1488s and 1489s to talk to the RS366 connector). A goolge search for RS366 provided me with a pinout (which I had anyway) and brief descriptions of the signals. But I'd like more :-). In particular, does anyone know a free (or relatively cheap) more complete spec. I;d like to know the timeing of the various handshake signals, and the encoding of the 4-bit digit-to-dial lines (it's not even obvious that '0' is sent as 0000...). What would be _really_ nice would be the schematic of an old (pre-microcontorller [1]) ACU with an RS366 interface. I don't suppose anyone knows of one. ]1] Since the HP11284 dates from 1974-ish, I would guess the RS366 interface is even older, and that discrete-logic implementations of the ACU must have existed. -tony

Archiving workstation hard drives

I think it is. Modern systems will be the ones that have mass storage systems and networks capable of dealing with disc dumps. When I've done this, though, I've written my own disc dumping code using SCSI command blocks to the low-level interface. This was necessary for archiving TI Explorer discs, which have 256 byte blocks but are SCSI devices (MFM drive and ACB 4000 host adapter).

Strange drive from MegaTape Corp.

by cheri-post＠web.de

Hello all, two daysw ago, I aquired a microVAX II with a RA81 and a tape drive. At the beginning, I thought that it was a half inch tape drive (toploader stype), but it turned out to be a special thing. Model type is : MT500C, the "C" standing for a cache option (128KB). The drive dates back from 1986, uses 24 tracks and can save 500 MB, which is way more than the 9-track reel tapes can store. It can be connected to a pertec controller. It seems to special because I couldn't find any information for it except for a german site from which obtained the information I provided earlier. Does anybody on the list knows anything about it ? Any experiences ? Documentation would certainly help. I don't even know where to get media for this thing. I got it whitout any media.

Paradise VGA longshot

by trixter＠oldskool.org

I know this is a longshot, but I'm looking for the settings of all five DIP switches on a Paradise VGA card from 1990. It has two strings on the board, either of which could be the make/model: PWBA 4316 0134-000 or PW800 VGA I'm assuming it's a paradise card, because the actual chip on it is from Western Digital Corp. (a WD90C11-LR) and Paradise used them nearly exclusively. The reason I'm asking is because I'm looking for an 8-bit ISA VGA card, and while this card is 16-bit, some of them could be DIP-switched to run in an 8-bit slot. There are five DIP switches on the backplate. No, I am not going to plug it into my 5160 and power cycle it 32 times to go hunting for something that works :) -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

Heathkit-Zenith H/Z-19

by ericj2190＠gmail.com

I have an old Heathkit-Zenith H/Z-19 terminal, and I am trying to use it to connect to a Linux system. I have it set up successfully to connect to the Linux machine, but I have a small problem. The bottom half of the H/Z-19 screen is filled with "p"s in reverse video. When I reach that part of the screen, everything I receive is gibberish. Most of the characters show up as some other character. Once I reach the very bottom of the screen, the "p"s scroll up with the rest of the text, but come back again from the bottom. I believe this is a memory problem, but I do not know if I am correct. Do you know what could be causing this? If so, how could I fix it?

5-6 random vax 4000 cables for postage

by brad＠heeltoe.com

I have about 10 pounds (weight) of random cables which I believe where used to connect two vax 4000 boxes. One end looks like scsi-2 but the other is something similar but not (I think these connected the two qbuses) Also there is a round cable with 2x3 .1" blocks (no idea, but related?) a cable which looks like it goes from a 50 pin .1" scsi header to a centronics scsi (hint: there is sharpie saying "8mm") two cables which looks like giant multirow; I think these connected an outboard RX50 box to something else. I was going to chuck these or put them on ebay. If anyone wants to pay postage (10-12 pounds, from zip 02476 in the USA), let me know. ps: I also have a vax 4000 box I no longer need with some disks and a cpu if anyone *local* wants to come by and pick it up; it ran vms once. send email off line if interested -brad

Having potentially damaging voltage on a connector that is not needed doesn't sound like good practices to me. I have the service manual here for this drive. No where does it say that pin 4 is not connected to anything. Nor do the schematics I have show that this drive's 7812 (which is how it is referenced in the print) is optional. The only source for +12 on this schematic is the 7812, derrived from the +24v line on Pin 1. Tandy also uses the same connector on the same power supply wiring harness, but with a completely different pinout (and using the same color scheme in some instances) to provide power to the card cage riser IN THE SAME MACHINE. If you use this connector on the drive instead of the riser, bad things happen. If you use the drive power connector on the riser, bad things happen. The only way to tell them apart reliably is that the drive power cable has two connectors (to power 2 drives) and the riser power connector has only one AMP connector. By the way, if anyone needs these connectors, they are stocked by Mouser and are about $3.50 each. Search for AMP 1-480270-0. I'm reworking a (different) power supply so I can put several TM848-2e drives in an enclosure for imaging disks from a PC. I also found 18ga hookup wire in 100' spools for less than $10 per spool at Jameco. It may save some wiring, but I still think it is a poor practice.

Component level repair

by Billy.Pettit＠wdc.com

William Donzelli wrote: Keep in mind that there are costs beyond that dollar. Yes, the costs of the parts is obvious, and the techs time is also pretty obvious, but there is more. WAY more. Doing more component level repair means more techs on staff. More salaries. With more salaries comes more health care costs, more little benefits, more equipment, more floorspace, which mean a bigger building - and then there are the extra personnel people needed to handle the techs - and their salaries, health care costs, little benefits, equipment, floorspace - which means you need an even bigger building, with more maintenance staff, and their salaries, health care costs, little benefits, equipment, floorspace - which now with a bigger building comes more property taxes, maintenance costs, material handling equipment and the servicing they always need, and then the new shelves to put the part, and the costs to erect them, which may mean some temps or even more maintenance personnel... OK, I could go on ALL NIGHT. Yes, the costs incurred for repairing that little dollar part may have only tiny fractional effects on all of the above mentioned stuff, but as things start to multiply, you find that there is a lot of money being dumped into a department that does not actually make any money. -- Will ------------------------------------ Finally, a little reality comes into this discussion. Everything William describes is normal for this industry. You will find it labeled different ways, but it is real actual costs to support a maintenance organization. (The last management textbook I saw called it MLB - materials, labour, burden.) In Silicon Valley, MLB runs from 100% to 250% of the technician's salary. In Asia, we can usually get it down to 80%, and the salary is lower. I think everyone who looks at this issue forgets that technicians are human. They have needs. They like to be paid; they need tools and space; they only work so long. To date, nobody has found a way to automate their skills. So this overhead is a real cost to an organization. And to William's final and most critical point - repair sections are not a profit and loss center. They represent only loss - they do not generate income. So if you set up a business making widgets and they can break and need repair, you have to make a choice. Do you just replace them or do you fix them? A repair department is a constant drain of money and resources. Replacement-only can take advantage of the volume/cost curve. It is the cheapest alternative. It may look like you are wasting money, spending hundreds to replace 1-2 dollar components. But looking at the overall costs to a business, it is extremely unlikely to economically viable to repair parts. You have to look at the real cost to your business, and not the cost of failing element. And for all of you who think this is a deplorable recent trend, you are wrong. These same factors existed from the very beginning of the computer industry. The cost of the maintenance on the very first systems was already one of the biggest expenses faced by the companies. It was a major factor in the demise of many of the early companies. They found their MLB exceeding their profit; and they couldn't do much to change it, since it doesn't create income. Even our favorite company here, DEC found that the maintenance and support was by far the biggest department in the company. Some third party companies like Bell Atlantic saw it as an opportunity. But in the end, they all faced the same factors - huge MLB, low income. So coming back full circle we have the hobbyists on this list who repair for the love of it. They bitch about the lack of documentation or parts. But they don't accept that the generation of documents, parts, reparability has a very high cost associated with it. And there is no income associated with creating those items. With all our high level skills, none of us got rich. It is not a marketable skill in a world focused on profit. Billy

My 386 laptop HD is dead. The solution: an IDE to CF adapter

by vax9000＠gmail.com

The laptop served me as a terminal, after the flyback transformer of my VT320 died. (Side info: there are new VT320 flyback transformers on ebay for $4 each. But the news is too late for me.) I was facing the question as what to do. Buy a real terminal? Buy another 8086-386 laptop? Buy a mac SE? Buy a small used IDE HD? Buy serial cable for the HP 100LX I have? Replace the unreliable floppy drive? After one hour of surfing the internet, I finally bought 4 IDE-CF adapters (laptop and desktop versions, $2 each). One for the laptop, one for the pentium PC linux router, one for the 386 desktop. Just want to share the experience with you so you do not need to waste the 1 hour as I did. vax, 9000

I didn't like that either.

And I see Marvin as much more like Bender than like the Disney cute one.

RX01/02 compatibility, OS/8 conversion

by rick＠rickmurphy.net

I happened to luck into someone this week on eBay who recently put up my OS/8 Adventure sources for sale.. he's offered to put the source onto floppies from his system. However, all he has is a RX01 drive. I've got some floppies around, but they may have been "formatted" by a RX02. I don't remember if they're still compatible with the '01. Is there any hope there, or anyone with a few (3) RX01 disks? More importantly, is there anyone on the list that can dump a set of files from an RX01 in OS/8 format so I can recover them? It'd be very cool to have the RALF source back. -Rick

Programming the PDP-11/10 Videos on YouTube

by dzubint＠vcn.bc.ca

I don't know why, but instead of typing in "Paris Hilton" into the YouTube search engine, I typed "PDP-11" and found a set of four videos called "Programming the PDP11" from Douglas Harms at DePauw University in Indiana, USA made in 2001 and portrayed as a Star-Trek-holodeck simulation back to the 1970s They are really funny and quite entertaining to watch. Quotes like Q: "What's 'paper tape'?" A: "It's very similar to the punch cards which I'm sure you've used" You can watch them on YouTube http://www.youtube.com/watch?v=XV-7J5y1TQc is part 1 of 4 http://www.youtube.com/watch?v=7zaaD_xP6nU is part 2 of 4 http://www.youtube.com/watch?v=xiE2QldpQRQ is part 3 of 4 and http://www.youtube.com/watch?v=NUSn59iY8U8 is part 4 of 4 Or you can get them (Apple Quicktime .MOV format) at the http://fs6.depauw.edu/~dharms/pdp11/ web page. see also: http://www.classiccmp.org/pipermail/cctalk/2000-March/142575.html Nice to see video of the old fanfold paper tape reader in action.

IBM 6580 Displaywriter

by cclist＠sydex.com

The recent talk about two old Displaywriters being up for grabs got me to thinking about something that I've left hanging out in my "things to do" list. Does anyone know the internals of the Displaywriter file format? The disks themselves are SSSD with the first track being 26x128 byte sectors and the remainder 15x256. The encoding is EBCDIC for the text, obviously, but the structure has eluded me (or I've been just too lazy to figure it out). My notes from years ago say that it appears to be a two-level sort of affair, with the top level referring to documents and the second referring to pages within the documents--and then I became distracted and that's where my notes leave off. Does anyone know anything more about these things? I'd like to close this item out in my "things to do list'. Cheers, Chuck

OT: faking a VGA display

by julesrichardsonuk＠yahoo.co.uk

Some of you here might know this :) I've got a system here where I need to make it think that there's a monitor plugged into its VGA port even when there isn't (long story). Plugging a real CRT into the port even when that CRT is switched off and unplugged from the AC supply works, so there's obviously some way of doing it. Measuring the CRT above (switched off, unplugged from AC, and unplugged from the device) with respect to the VGA connector's shield gives me the following readings: pin sig value 1 R 76ohm 2 G 76ohm 3 B 76ohm 4 NC GND 5 GND GND 6 GND GND 7 GND GND 8 GND GND 9 NC infinite resistance 10 GND GND 11 NC GND 12 DDC DAT 8.1Kohm (initially 7.6Kohm, rose at first then steadied) 13 HSYNC 4.6Kohm 14 VSYNC 4.7Kohm 15 DDC CLK 8.1Kohm (initially 7.6Kohm, rose at first then steadied) Any suggestions? Do I just need 76ohm resistors to ground on the RGB lines (and possibly 4.7Kohm resistors to ground on HSYNC and VSYNC)? Or is there likely something more subtle going on that I need to incorporate into my "fake" connector? (Given that VGA supplies no DC out, it can't be anything too complex!) cheers Jules

My 386 laptop HD is dead. The solution: an IDE to CF adapter

by Billy.Pettit＠wdc.com

Brad Parker wrote: Heh. I remember someone asking me (at work) if a 3.5" ST-506 drive would work in zero G. I ask where it was installed and they said a KC-135 :-) Apparently someone wanted to use one in the "vomit comet"... and apparently it worked (at least they never complained that it didn't) I don't know how high those where pressurized, but I'd guess around 8000ft. No doubt the old drives didn't need as much air density; the flying height was not that low. I have no idea how air pressure affects the boundary layer over the surface - I assume less density translates to less drag and then to a lower flight. -brad ---------------------------------------- Cold is not nice to disk drives. More than flying height, the mechanical parts become stiffer and don't flex correctly. Bearings becomse stiff and generate vibration. Seals shrink. A lot of work is being done on self heating. This will be needed when drives go into cell phones in the near future. The drive uses the electronics to get to a certain temperature before loading the heads off the ramp. Air pressure does affect the boundary layer, especially at high RPM. There comes a point where it goes negative and sucks the heads down. The testing I saw showed this somewhere around 18-20K RPM. For drives on the market today, flying height is controlled and compensates for altitude. As for cell phones and hard drives, yes, I know that Flash is getting cheaper and is in a surplus situation right now. And with 4 level cells coming along, the cost per bit is going down. But hard drives will still be used in cell phones, because those devices have exploding storage requirements, thanks to new features. Look at Apple's iPhone, with all the bells and whistles. And only 8GB of storage. They've sold millions of iPods with 20, 30, 40, and 60GB of storage. Those users will demand more storage as they use the iPhone. Cell phones do now and will in the future use hard drives. Cold is one of the biggest unsolved problems. Shock is looking so-so with free fall sensors. Power cosumption is the biggest detractor. But a hybrid with a big cache could solve that. Billy

My 386 laptop HD is dead. The solution: an IDE to CF adapter

by Billy.Pettit＠wdc.com

Jim Leonard wrote: Yep! There are only two drawbacks to microdrives: - Slower than real flash - Can't use 6000+ feet above sea level (lack of air pressure can make the drive go wonky or, rarely, break it) -- Jim Leonard --------------------------- I have to strongly dispute this; The IBM (later Hitachi) MicroDrive was rated at 10K feet. I did competitive testing on it and the Seagate 1" drive and both had no problems at 10K feet. In fact both + the WD 1" drive work fine well past 10K feet. Come to that, Maxtor, Miniscribe, IBM and DEC built drives in Colorado well above 6000 feet. Apple used to have a factory at Fountain (6400 feet). So this simply isn't true. The biggest customer of the MicroDrive - Apple iPods - work great on the ski slopes. They also work great in Reno at 7000+ feet. I can personally vouch for this and I'm certain others on the list can too. They also work fine on airplanes, which are pressurized at 8000 feet. I have never heard of a drive breaking because of altitude. Rarely, you get a head gimbals or suspension problem that doesn't like 9000+ feet. But that is a defective drive, not the rule. All drive vendors and many OEM buyers do extensive testing to ensure this. And all heads are testing for flying height before being installed in a drive. Finally, today's drives utilize Dynamic Flying Height technology which uses a heating element in the head to maintain constant controlled flying height. Altitude is not a problem with any drive on the market today. Billy

DEC MMJ, eBay madness

by tothwolf＠concentric.net

I've been active on classiccmp for a good many years now and up until now have rather enjoyed making custom and hard to find cables for others in the classicmp community. Recently, someone on eBay managed to get their hands on a spool of genuine DEC flat cord, bought a knock-off MMJ type tool (I saw him purchase it) and started selling poor quality MMJ cables. I couldn't compete and quit making standard MMJ cables, but this weekend he started making H8571-J work-alike adapters to undercut me there too. I know this person is active on the classiccmp mailing list. He started listing his cables shortly after my post when I asked which length of MMJ cables would be the most useful to the majority of the list members. His eBay id is currently "cheshire-cat-computers" but he had been going by "ggggmmmm" up until Jan 5th. I've been going in the hole now for 2-3 months with the listings for cables and I think after today I won't be listing any more. I've now run out of 6-conductor flat cable and I'm down to less than 2 dozen loose MMJ plugs and I'm thinking that its just not worth the trouble anymore. I still have some adapter kits that I made up a few weeks ago, but I think I'm just going to toss them in the junk box and forget about them. I just have no desire to compete with someone who wants to undercut me the way he has done as it appears my time is worth a lot more to me than his is to him. It was certainly fun while it lasted, and I shipped cables all over the place, from Australia to Germany to the UK, and of course the USA and got to talk to all kinds of people. I even had a few go to a couple of people in the armed forces, so I guess they are still using DEC gear too :) -Toth

laptops and 5.25 inch floppy drives?

by Watzman＠neo.rr.com

Re: "would it be possible to get a 5.25 to work in say an older laptop w/an integral 3.5?" Maybe. Quite a few Toshiba laptops have an external floppy drive port. It is a true floppy port, designed to interface to a 34-pin floppy interface. Two different connectors were used, the "standard" Toshiba floppy port connector used in every model computer except the Tecra 8000, and a slightly different connector used in the Tecra 8000 series. These connectors are found in the Satellite 400 series laptops (two distinctly different sets of laptops, the "early" 400 series (400 to 435, Pentium I's) and the "late" 400 series, 440 to 490, Pentium MMX and even a Pentium II). They are also found in the Tecra 8000 (different connector), which used both Pentium II and Pentium III CPU (266MHz to about 500MHz). I think that there are other Toshiba laptops that have a similar connector as well, in the Tecra and Portege line (and also the libretto models). Note, since this port was used for the 3.5" floppy drive, you generally won't be able to have both 3.5" and 5.25" drives installed at the same time (but, on some of these, the very reason for the port was that there was an internal drive bay that could either contain the floppy drive internally, or a CD-ROM drive. Not sure if you could use an internal and an external floppy concurrently in those models). Also, Toshiba assumed that the external drive was 3.5" and there is no provision in the BIOS to configure the bios and software for any other floppy drive format. Finally, the hardware reconfiguration (cable) will be a bitch to figure out, although it is conceptually possible. While the external floppy has the 34-pin electrical interface, mechanically it's not a standard 34-pin IDC connector, it's a flat "flex cable", and reworking the cable to connect to a 34-pin standard interface will take some effort. The good news is that you can buy entire laptops in this series for as little as $15, and you can find the external floppy caddies for $5 (source of the cable and connector that mates with the laptop).

That this harness has power going to a drive power plug that isn't used it typical of Tandy's shortcuts. They banked on the fact that Tandon would NEVER put another pin in that socket. ---------------------------------------------------------------------- Well, in all fairness to Tandy... Since the schematic for the TM848 shows what seems to be an option to omit the 12V regulator and supply the 12V through the power plug, perhaps Tandy at one time used (or planned to use) drives requiring 12V and kept the 12V supply on the connector for compatibility. Wouldn't be a problem since that pin is physically missing on "normal" drives. Sorta makes sense; in the S-100 world there generally wasn't a 12V supply and every drive needed its own regulator(s), whereas if a system already had a 12V supply then using the 24V and another regulator on the drive would be redundant and just waste power. And there are certainly numerous custom versions of the TM848 around, so you can't count on any particular drive being plug-compatible anyway. Yes, if you happened to plug a drive with the power off option on pin 4 into your 6000, there probably would be some magic smoke... Things weren't quite as "standard" in those days as they are today, FWTW. m

Sooner or later there will > (thankfully) be pressure on manufacturers to make their products be more > maintainable and last for longer. The way things are going, being able to maintain a buggy whip won't be economically feasible or an asset to any mainstream company. Technology changes, evolves, and rarely results in something being simpler and easier to fix. I do like repairing at the component level, but just don't have time for it right now. But as Tony mentioned, it is a puzzle, and the MINDSET that allows troubleshooting is just not something everyone has. One of my favorite examples was back when I was doing field maintenance, I got a call from a customer who couldn't get their machine to work. So I flew down to take a look, was picked up by the plant manager, and taken to the machine. While he went to get the tech, I looked at it and had it working in a couple of minutes later when they returned. The problem was strictly mechanical (an air cylinder shaft had come unscrewed from the piston), and they had *assumed* it was an electrical problem. And most of us (at least those of us do/did troubleshooting as a job) have had the experience of troubleshooting equipment where the problem turned out to be the switch needed to be turned on, or the unit plugged in. Developing a mental picture (I think in terms of block diagrams) of how something works is crucial to being able to troubleshoot it.

The wiring harness from the power supply does connect +5, +12, and +24 to the plug that goes into the drive. However the TM848-2 drives have pin 4 vacant on the connector on the drive. That is, there is no pin there.

Component level repair

Tony Duell wrote: OK, let me raise a few points. I think _everyone_ here could do component-level troubleshooting if they wanted to. It's mostly a matter of logical reasoning, and I think everone here can think logically. This last part may explain why I'm so fanatical about it. I find it fun. I like solving puzzles. I like logic puzzles particularly. And that's exactly what rtoubleshooting should be. A puzzle. It's like detective work. You gather the clues, think about them, and find the cluprit. Fortunately for me, the rsults of being wrong are somewhat less serious than sending an innocent man to the gallows ;-) I guess troubelshooting is one reason that I mess around with old hardware. I do enjoy it. -tony ------------------------------------------------- Tony, There are different motivations for different people. I don't share your love of fixing things for the sake of fixing them. After 45 years of repairing electronic problems for a living, I'd like a break. Puzzles are fine for minor recreation, but a full time diet is very boring. Broken malfunctioning computers have gotten old. Time for some fun. I buy new computers so I can USE them. I want to have pwerful tools to create, research, edit, post. I buy new TVs so I DON'T have to fix them. I'd rather watch programs on them. I don't have to prove to myself or anyone else that I can troubleshoot an old circuit. Or a new one for that matter. Same for cars and cameras. My pleasure is in driving someplace I haven't been and experiencing it. Or visiting friends. Staying home and overhauling the engine is not a pleasure. Buying a camera to fix it is not a joyous thing. The creative part is in the picture taking. So I DON'T agree that everyone on the list should be able to troubleshoot. It is a minor facet of the hobby of retrocomputing, not the raison d'etre of the hobby. Billy

Tandon TM848-2 Floppy drive power

Looks like there was also an option (on the schematic, not the drive) to use pin 4 (and/or pin 3) of the AMP connector to sense when a disk was inserted and turn power to the drive on/off. BTW, on the drive the fuse F1 is in the main +24V line, whereas the schematic shows it only in the branch going to the 12V regulator. Hope that's clearer than mud & helps. mike

Tools - security bit set?

by mtapley＠swri.edu

All, a while ago was posted here a recommendation for a set of security bits. I have at least two items that I can't (reversibly) get into without them - one is a power supply unit for a PowerBook 3400, which needs a tamperproof torx (I think). What's an affordable (in the Duell sense) set of tools that anyone can recommend to me? I'm hoping to get tamperproof Torx, triangle-head, etc. in several different sizes, so I can keep the whole set together and just grab it when someone assumes I'm about to kill myself. -- Mark Tapley, Dwarf Engineer (I haven't cleared my neighborhood) 210-379-4635 Dwarf Phone, 210-522-6025 Office Phone

Archiving workstation hard drives

by aek＠bitsavers.org

Suppose the drives were from the Lilith/Eve workstations. Would the unix trick of using dd still work? -- nope. they had their own custom drive interface. same is true for pretty much every disc before SCSI common command set. while 512 byte block scsi or ide interfaced mass storage devices now seem like the only things that ever existed, before the mid 80's there was no real block-level hard disc standard across manufacturers. the closest would have been hpib, but that was really only used by HP.

There are many instances where you want the component flush. For example, an RF can - don't want the leg to touch. Same for a daughter board. Or a PCB that fits into a tight case. And so on. Flush cutters are an extremely useful tool and you want one that give a clean sharp cut with damaging the surface of the PCB. It's the same principle as using a saw with no tooth offset to trim a dowel pin - cut but don't damage. Billy

Sun Graphics Options

The "really off-topic" stuff I'm talking about are the current cards- those Suns are outside of my budget. Creator was mid to late '90s and was the first Sun 24-bit midrange option (I don't think there were any 8-bit UPA graphics options). GP2 was, I think (don't have one) a single 9-U VME board that attached to the CG9 via a private bus on the P2 or P3. CG13 looks to be unaccelerated based on anecdotal evidence. Does anyone know if the S24 (SS5 AFX framebuffer) was accelerated? This doesn't cover 3rd party products, either

Strange things found in a free SPARC 20

by ethan.dicks＠gmail.com

So I get this pair of free SS20s today at the weekly geek lunch at the Chinese restaurant down the street - one nice, clean one, and one that, um... well... was corroded inside due to an unfortunate meeting with a dog, I'm told. I stripped down the soiled unit before I even got home to recover a (clean) 1"-tall Toshiba SCSI CD-ROM, two (clean) SM50 processor modules, and a mixed pile of DIMMs with some corrosion on the fingers. The motherboard was a total loss, as was the chassis. I have washed and brushed the SIMMs, a mix of 8MB and 32MB - not sure about a couple of them, but most seem to be visually intact. I was planning on an alkalai wash before testing them. The other box being clean made it a good candidate to boot up... it had a single SM50 (now two), 48MB of RAM, a TGX framebuffer, and an internal SCSI drive of a type I'd never seen before. I had to google it - an ST5660NC. I was surprised to confirm that even though it was an SCA-connector drive, it was a whopping 545MB, and *narrow* (thus the "NC"). I didn't know anyone made a) SCA drives below 1GB, and b) narrow SCSI SCA drives. I think the drive bracket is probably one of the most expensive things in the box, really. I think there was some recent list traffic about using an SS20 as, essentially, an X terminal with that optional internal frame buffer, but since I don't have one, I'm thinking "headless server". Not as powerful as the cheapest of "haul-it-away" commodity boxes, but substantially more robust. At least I'd expect this box to stay up for 6 months at a time. At least it runs Solaris 9. -ethan

Ah yes, here it is: the GP2 graphics processor. VME based, with Weitek engines. Then there was the Leo/ZX option for SBUS. Can't tell you anything about performance of either of these two. With the introduction of the UPA bus things got better: Sun introduced Creator/Creator3d and Elite3d. Of course, none of these graphics could touch what SGI was putting out, but it was a valiant attempt. Creator3d used the SPARC for geometry but had onboard Z-buffer calculations, Elite3d had a full graphics pipeline but not much texture cache. Can't say anything about the really off-topic stuff for the current machines.

SPEC Computer Trainer

by Billy.Pettit＠wdc.com

In the summer of 1961, I worked on a computer made by CCC (California Computer Co. ?) It used a magneto-resistive delay line for main memory. The model number was SPEC, which stood for Special Purpose Educational Computer. It was aimed at computer training in the military (I was in the Army at the time). It was a small sub-desk size computer, certainly not a mini. Only had 128 words of meory. I thought my memory was betraying me until I recently found a brochure that has a poor picture of it. And I found one of my coding sheets from the class. But that's all. Does any one on the list have anything else? Would love to see more pictures or a schematic. How about a manual? Or even more basic - has anyone else even heard of it? Billy

FS: LD-V1000

by marvin＠rain.org

I just got in some LD-V1000 laserdisk players that are basically NOS units. The LD-V1000 was used for a number of laserdisk games including Cinamatronics Space Ace. They were powered up quite a few years ago and there is a sticker on each one with the measured laser output (76 mW for the one in front of me.) While the units themselves are pretty much prisitine, the boxes are in probably very good condition and show signs of mice/rats having visited. $125.00 plus $10.00 packing and shipping from zipcode 93105. They will be shipped in another box 30" x 24" x 12". Each one will be tested to make sure it will play okay, and will be shipped with the lens cap and a shipping screw of some sort (these had the shipping screw removed, and I'm not sure yet exactly what they look like.) No paperwork except the registration card on the outside of the box.

PAiA 8700

I suppose I'll be sorry for this, but I want to mention that one of the hardest to find early 6502 systems just showed up on eBay: the PAiA 8700. But it wasn't on the vintage list; it was on the music instrument category. Most of these were built into keyboards. I've been looking for one of these for 5 years and only seen 3 of tem on eBay. Always get outbid. Had to stop bidding on this one at $93.. Anyway, if anyone else wants one for their collection, take a look at this: 110079964730 You can see the keyboard and the display in one picture. The description gives it away. So if you are looking for these, do a search pointed to midi keyboards or PAiA. Billy
