UK: tape winder? Atlas Autocode charset (flexowriter) conversion?

by gtoal＠gtoal.com

Chris Whitfield and Ian Young have interfaced the borrowed optical paper tape reader that we were kindly loaned and have it working on a PC. Before we go to the site that has the paper tapes (several dozens) does anyone have a winder we could borrow to save winding them all back up by hand? Also before I write it (I have some paper documentation to work from describing the Atlas Autocode character set, which is from the Flexowriter printers that were attached to it) does anyone already have any code to convert from the flexowriter char set to ascii in any form? We're hoping to get a copy of the Atlas Autocode compiler on paper tape... Graham

3.5" drives (720,1.44 or 2.88)

by kenziem＠sympatico.ca

Is there a quick and easy way to tell them a part? In a previous thread on separating 5.25 drives there was mention of testing for the number of sectors. Does someone know where such a program may be located?

ECMA 46 tape standard

by coredump＠gifford.co.uk

I've been asked about a quarter-inch tape standard from 1976, called ECMA-46. It's apparently 63 bits per mm, phase encoded. I work that out to 1600 bits per inch. Now, is this one of the early QIC (Quarter- Inch Committee) standards? Could it be QIC-11, the four-track system used on Sun-2 machines? Or is it something else entirely? And how could such a tape be read, nowadays? -- John Honniball coredump(a)gifford.co.uk

New additions-- Lots of coco computer stuff

by SUPRDAVE＠aol.com

A guy that's seen my website contacted me and brought me a trunkload of color computer stuff up from SC. I got a color computer 1 and 3, a multipack interface for the model 1, dozens of programs on tape, zenith display, dual disk drives, tandy dmp102 printer, a mix of about 200 magazines for the coco, like rainbow, hot coco and some others. also got a tutorial on tape for the 6809 and some assembler program. Everything's dusty, but in all over good shape. The magazines really show quite a color computer following back in the day. Some magazines are over 300 pages each. -- Antique Computer Virtual Museum www.nothingtodo.org

Twinhead Superset 310

by gesar＠tiscalinet.ch

Dear Listers, I'm completely new to this list as well as to vintage PCs and I hope to get some help from you knowledgeable folks in respect to a box I recently got from a friend of mine. It's a Twinhead Superset 310 with a 80286 processor, 1 MB of RAM, a ST-251 harddisk and 5,25" floppy-drive (IBM YD-380) for 1.2 MB disks. The battery was gone, so at every startup, I had to type in the configuration setup. I ONCE only managed to boot the machine which immediately started WordPerfect 5. I typed a few sentences but I could not save this text (the program all the time asking for a floppy I did not have) nor could I end the application or shut down the system (I REALLY do not know anything about DOS). So, I just powered down the machine. Afterwards, I never again managed to boot the PC, as it always asked for a floppy. Meanwhile, I managed to de-solder the 3.6 V battery and I'll look for a replacement. But there are a lot of questions, as I'd really like to learn to get this machine running and as I'd like to handle it: - The mouse-port on the back looks like a P/S2 but its larger in diameter. What standard is this? - There is one ISA-card I do not know what it is for. It has an external connector just looking like a VGA, but the monitor did not work with that. Furthermore, there are two black connectors ("wholes") about the size of an RCA audio in/out. A networking card (BNC)? - Generally: Does somebody know this machine? Somebody has manuals? Best thanks for caring! Steff

Backing up ST506 disks

by julesrichardsonuk＠yahoo.co.uk

Hi all, I'm just wondering how to back up the hard drive (a 20MB MFM) in my Research Machines fileserver. The system runs CP/M, has a couple of floppy drives, and the hard disk is hooked up to a Xebec controller with a SASI bus linking it to the host controller in the fileserver. There are actually two problems: 1) Getting the data off the hard drive somehow (possibly via floppy) and being able to read it on another system (ideally a PC I suppose) 2) Being able to rebuild the system if/when the hard drive fails. Thoughts on both are welcome! I don't have any kind of OS source media for the system, and it wouldn't surprise me if it isn't the only survivor :-( Maybe there are utilities on the system itself to recreate bootable OS media, but my knowledge of CP/M is a little lacking! For my old SCSI systems I tend to hold a raw block-by-block backup image of the drive by putting the hard disk in a PC with Linux and dragging data off that way. If the drive fails and I can't get an identical replacement, a slightly larger drive still works with a little bit of wastage. Due to the relationship between the controller and drive using ST506 I gather things are probably a little more complex though... cheers Jules ===== Backward conditioning: putting saliva in a dog's mouth in an attempt to make a bell ring. ________________________________________________________________________ Want to chat instantly with your online friends?

Another Intel! E320EB

by rigdonj＠cfl.rr.com

I seem to be on a roll lately so this weekend I dug out an Intel that I bought off of E-bay some time ago but never got around to checking out. Disassembled, cleaned and inspected it. Found out that it is an Intel E320EB and uses Multibus cards. Oh, and it's serial number E00001000! I couldn't find a description of it in any of my Intel books but it has a CPU DX-2 66MHz CPU with built-in SCSI port and a 32Mb daughterboard! Also has three 4-port Intel iSBC 544 Communications cards, a SCSI 3.5" floppy drive, SCSI tape drive and two SCSI had drives. The CPU card and daughterboard are made by Radisys. After some checking I found that Radisys bought Intels Multibus I line from Intel in 1996. The ROMs on this one are also dated 1996. Today I made a cable for it and connected it to terminal and tried it out. It booted up fine and passed all the self-test. It boots up and loads IRMX III.2.2. Boot like the Intel 310 I don't have the account name and passwords so I couldn't log in. Anyone know any more about the 320 systems or have any idea of how to get into the iRMX system? Joe

8 inch floppy drives available

by r_beaudry＠hotmail.com

Hello all, I have the following 8" floppy drives available for $5.00 + shipping. The $5.00 covers the cost of a brand-new box, shipping materials, and my time to pack/ship. These drives are working pulls, but have not been tested in a few years. I may have manuals for the Shugarts, so ask if you need one (no extra cost). In order to be fair to digest and international users, I'll take emails from interested people until Tuesday, August 5th at midnight. Then I'll randomly choose people to ship the drives to. Please email OFF-LIST, and include a ZIP code or country so I can quote shipping. Shipping will be by USPS, from ZIP 01473. Shipping weight is approximately 25 lbs. per drive. I will weigh them and give an exact shipping quote when I determine who gets them. I CANNOT combine more than one into a box because of size/weight constraints (i.e., too big and heavy for me to carry!). You can go to www.usps.com and get a shipping estimate. Here's the list: - Qty. 1 Shugart 851 - Qty. 3 Shugart 801 - Qty. 2 Shugart 800-2 - Qty. 1 Qumetrak 842 - Qty. 1 Qume DT/8 (this looks like the 842, but I have no manual to tell the difference).

Backing up ST506 disks

by aek＠spies.com

Put an ST506 controller into a PC. ST506/412 was the defacto standard on PCs until IDE. although most PC people erroneously refer to the cabling and interface as "MFM". The controllers used by IBM in the XT were made by Xebec. Once you have a controller and drive in your PC, you can write the code to read and write sectors to be able to copy a drive. -- It would be easier to use basic SCSI commands to talk to the S1410 controller directly. I have the documentation on line, and as long as no other peripheral is on the SCSI chain, it should work fine (SCSI is a superset of SASI) When you write the copy program, remember to have some fallback strategy WHEN you read a bad sector (filling with ascii "BAD SECT" for example) since you may not get any data back. You'll also need to figure out the disc geometry, sector length, etc. since you have to set these parameters into the S1410 before you can do anything. This may require some experimentation, but it isn't likely that they would have used anything other than 128,256, or 512 bytes/sector. the S1410 manual can be found at www.spies.com/aek/pdf/xebec/S1410Man.pdf

Learn enough about the system to extract the code needed to do a bootstrap. It will be worth your investment in time. The amount you'll learn will be more valuable than the boot strap code. The simples bootstrap is with some serial input to drive. You should get a second drive to fiddle with, that can later be used as a backup. Dwight > >Thoughts on both are welcome!

OT: SCA Drives in StorageWorks SSB's

by healyzh＠aracnet.com

This is a bit modern for the list, but I'm hoping someone here has some experience. I've just been given a pair of BA356 enclosures, and the one has 6 empty DS-RZ1CB-VW SSB's. The shelf itself is a BA356-KD with BA35X-MD 2X fans, and a BA35X-MH 16-bit I/O Personality Module. My question is, while the DS-RZ1CB-VW SSB's are intended for 4.3GB 7200RPM *SCA* drives, can they handle 9 or 18GB 10,000RPM SCA drives? If nothing else, I can always fill the shelf with RZ29-VW drives, but would prefer some 18GB drives if possible (I suppose I can always get some 7200RPM ones off of eBay). Zane -- -- | Zane H.

I drive by the site every now and again and shed a tear for what was once a wonderful place to lose an afternoon. Back around '89-91 I worked at MIT and Eli's was a prime source of parts for labs with tight hardware budgets to repair/upgrade their ailing MicroVAX II's and such. I remember wandering the shelves and seeing RX0n drive cabinets, whole pdp-11/44's, and other goodies that I didn't do anything about. What I did do was buy an SGI Iris 3130 with monitor -- nobody seemed to know what it was, but I got it to boot. I believe I paid $2k for that thing with 20" color monitor, and hauled it home in a friend's car. Fooled around with that for a couple months but something in the monitor went, probably a flyback. I decided by that time that I needed a Sun for a project I wanted to do when I returned to college (anybody remember UCB's Sprite?), so I sold the thing with a dead monitor for the same price. Who knows, maybe I could have gotten more, the thing was loaded with bitplane and Geometry Engine boards. But the weird System III derivative OS really put me off at the time. Manys the time I've wished I could go back in time and raid those shelves, or browse through the tables of electronics parts... --Steve.

IBM 5100 tinkering

by hansp＠citem.org

We did some tinkering with our IBM 5100 the other day with results which might be of interest. Our 5100 is a model A4; it has 64Kbytes of memory and APL (only). When we opened up the beastie for a service a year or so ago and speculated on the fact that there were no empty slots in the card cage (we do seem to have every built-in option made) which led us to propose that perhaps the BASIC interpreter was also included but made unavailable by the absence of the language selector switch on the front panel. Examining the cable harness behind the panel showed a particularly thick section encased in insulation tape just behind where the language select switch would be installed and tempting evidence of one, possibly two unconnected wires. At that time we went no further. This week we were prompted to revisit the 5100 with a view of seeing if we could in fact run BASIC. Carfully cutting open the insulating tape around the cable harness behind the language select switch position revealed two unconnected wires complete with tiny push on connectors. We jumpered the two wires, powered on the machine and waited with bated breath. Following the familiar self-test display we were presented with an unfamiliar prompt, not the APL one at all. A little fiddling with the keyboard quickly confirmed that we had BASIC operational! So at least the APL only versions of the 5100 are configured with the BASIC interpreter which is disabled simply by the absence of the language select switch. Our IBM engineer speculates that the reverse is not the case : the BASIC only configuration does not include the APL ROM code. Anyone care to experiment and confirm that? We are now installing a language select switch (though alas not of the same type as the others) and look forward to playing with BASIC on the machine. Does anyone know the price difference between the A4 and C4 models? I would hazard a guess that that switch cost several hundered dollars at least ;-) Oh, what prompted us to revist the 5100? We recently acquired a Commodore PET 2001 and on compiling some techinal notes for it found a web site stating that the PET was 2 to 3 times faster than the 5100. That statemnet surprised me and I wanted to confirm it. Early indication show that the two machines are remarkably alike in performance (another suprise) the following program runs in the same time (to the second) on both machines : 10 a = 0 20 print a, a*a, sqr(a) 30 a = a + 1 40 if a < 100 goto 20 50 stop The 5100 seems about 30% faster on though with the following program: 10 a = 0 20 b = a*a 25 c = sqr(a) 30 a = a + 1 40 if a < 100 goto 20 50 stop So it seems it is the display which slows it down.

need EISA config util for Everex STEP

by bear＠typewritten.org

I have an Everex STEPcube (12-slot, 80486) that I need a copy of the EISA config utility for. Apparently this was available until about a year ago as a download from everex.com. The site is now defunct. Failing the "correct" ECU I could experiment with another ECU, given just the CFG file for the motherboard. That file would be on the ECU disk, but I could also use it by itself (!EVX0101.CFG), in the absence of the complete ECU. Can anybody help? Thanks! ok bear

Logic Analyzer Pod Probes / Scope

I'm buying a Tektronix Logic Analyzer that has pods, but none of the test leads from the pod to the probe. They don't come up ebay often and when they do they are very expensive, almost as much as the logic analyzer itself. Any ideas on alternative sources for used probes or other makeshift alternatives? Also, anyone got a cheap (but good) oscilloscope they want to sell? I need some test equipment to attempt to diagnose some vintage hardware problems. Thanks, Chandra

Best way to Sell Old, Used Software and SW/dev Books w/little Collectible Value?

by dwallace＠m-net.arbornet.org

Hi, My first time posting here - apologies if I should have RTFM first on this topic. I have a mountain of dated (late 80s - early 90s vintage) and probably non-collectible software packages and books that it seems to me would be a waste to consign to a landfill. I mean stuff like: Clipper 5.2 Corel Draw (Win 3.1) Version 4 Quattro Pro for DOS Ami Pro for Win 3.1 Star Trek Screen Saver (ca. 1992) Borland C++ 3.1 for Windows and DOS with Application Frameworks Books such as "advanced c-struct programming" (OOP on C), Peter Norton's "Inside OS/2", Alan Holub's "Compiler Design in C", several different DOS and BIOS interrupt references, a book on device drivers for DOS (yechhh!)... When I think of all the money I squandered on this cr$p in past years so I could stay in place with idiot employers and not even advance, I want to go GAAAAH! I *also* want, if possible, to make a buck or two off the lot or individually, and remove it from my view and from my basement. The Rubbermaid containers it's in are probably worth much more than this stuff is worth. Maybe. I doubt that most of this stuff is even worth paying the advertising fee on Ebay, and there's a LOT of it. Maybe the thing to do would be to advertise a few of the "better" pieces (like the Holub book) on Ebay, and in that ad on Ebay link to "other articles for sale". Just to generate traffic from the Ebay placement. Ideas? Know of any brokers that would take the entire lot? Or, know of any Luddite communities that eschew sinful protected mode OSs in favor of simple, uncomplicated DOS and 286 level software that penalizes the sinful user with random lockups? :-) OK, that was reaching... Thanks!

pdp-8 serial numbers...

by mross666＠hotmail.com

Can anyone shed light... my 8/L has a serial number plate on the rear, with *two* numbers stamped on it, thus: 1127 963 How does that decode? Which, if either of those, is the real serial?

Intel 310?

by Innfogra＠aol.com

I am finally back online. July is a busy month for me as I wear several hats at the Oregon Country Fair and it occupies me for more than a month. I still have 4 intel 310 chassis, I can't seem to part with them and I have no idea what to do with them. They are good for industrial control as mentioned. I ran across a pair of 310s in the communication room of Fiji Telecom that I think are still there. It is a great development chassis in Multibus 1. Six slot desktop, 5 1/4" floppy and HD and sometimes a 1/4' tape drive. In the 1980s there were lots of different Multibus cards out there. I am surprised there are few in collections. We probably did trash more than a hundred in the late 1980s when we were buying truckloads of intel stuff. We sold a huge lot to InBus in the early 90s. As to the question of cracking a Xenix System? I have yet to figure that out myself. I was hoping someone out there had the secret or did it die with Larry? Paxton Astoria, OR

Analog computer article

by mranalog＠comcast.net

Hi All, If you are interested in building your own analog computer or just interested learning more about how an analog computer works, I found a PDF version of a 4 part construction article on the web. The article, I believe, is from Practical Electronics Magazine (UK) (date unknown, probably late 1970s). The amplifiers are 741 opamps. And the amplifiers even have overvoltage indicators which is a sophisticated feature usually found only on commercial computers. Part 1 is how an analog computer works Part 2 is construction details Part 3 is wiring and testing and Part 4 is programming and special circuits The file 2.25 MB Kronis, P., "Analogue Computer", Parts 1, 2, 3, 4 http://patrik.unx.nu/tech/analog_dator/anacomp.pdf --Doug ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://dcoward.best.vwh.net/analog =========================================

There are a LOT of 9825s out there. I have talked with these guys as well and their problem is getting the files off their last working tape. james.clements(a)robins.af.mil wrote: > Apparently there are some files that are protected some way.

I didn't know you could have protected files in the 9825, but if they have tried and failed, then we need to explore other ways of getting these files off the tape. So I was thinking, can another machine (e.g. HP 85) read 9825 tapes? I think the tape mechanism is the same, but I am not sure about the way data is organized on the tape. Thanks **vp

Intel 310?

by rigdonj＠cfl.rr.com

I've spent part of the last two days working on an Intel 310 that I found in a scrap place and finally got it working. I'm just wondering how common thse are. I searched the net and didn't find any on any web sites but a number of people's resumes mentioned using them at one time. Does anyone else on the list have one of these? If so does it still work? There's good picture of one at <http://valinor.ca/in310a.jpg>. Even thought they're in a desktop case, they still used Multibus cards. They ran either iRMX or XENIX (Mine has XENIX installed). Joe

How to break into a XENIX system?

by julesrichardsonuk＠yahoo.co.uk

> There's ten serial ports on it and they're numbered J20 to J32. > You'd think that the system port would be the lowest or maybe the > highest numbered port but Nooo, it's J31! My NCR Unix Tower has two 'special' serial ports on the back; ISTR that port B is the console, and port A is for a remote diagnostic modem. It's possible your system has a similar I suppose, and J32 is for a modem... > There's lots of bad blocks and such on the drive. I'm wondering if I should > just install iRMX on it and forget it. Comments? In situations like that I tend to pull the drive, drop it in a Linux system and grab a raw image of the disk to a file. At least then I have the data, even if accessing it can be a little complex. Format the drive then by all means, but if it has bad blocks it sounds like it might not be too healthy anyway... cheers Jules ===== Backward conditioning: putting saliva in a dog's mouth in an attempt to make a bell ring. ________________________________________________________________________ Want to chat instantly with your online friends?

shugart 900-2 and 902 disk drives?

The general specs( 8" FH 800k) are the same. > > Joe > Hi Joe The 900 series have a different connector for the cable. Instead of a .100 50 pin, it uses a .156 44 pin connector. I don't know about the 902 though. As I recall, it should be similar to the 800's. I have a 900 series drive in my Nicolet NC-80. If you have an extra, I've been looking to expand my machine to a dual floppy. Doing disk copies are a real pain. The machine has only 12Kx20 of core memory. Not much room for a bunch of disk buffers. Dwight

How to break into a XENIX system?

by rigdonj＠cfl.rr.com

I had some time to kill this morning so I drove over to the warehouse and worked on the Intel 310 and I finally got it running. As I suspected, the HD controller was mis-configured and I also got lucky and found the proper port for the system console. There's ten serial ports on it and they're numbered J20 to J32. You'd think that the system port would be the lowest or maybe the highest numbered port but Nooo, it's J31! I read through the few Intel 310 manuals that I have last night and they're not much help but they at least gave me the proper baud rate, parity, etc so that elimenated one unknown. Played around with the SDM and ROM diagnostics and all the hardware checks out perfectly. The bad news that the 310 has XENIX installed :-( I also couldn't log into the system as a user or super user since i don't know the account names or passwords. Does anyone have any idea how to break into a XENIX system? It's XENIX 286 -W- Version 3.0. There's lots of bad blocks and such on the drive. I'm wondering if I should just install iRMX on it and forget it. Comments? Joe

CFX-400 Case

by wrawbee＠hotmail.com

Stan, I've done some calling around and emailing. Casio has four distributors that they send replacement parts to. None of them have the case in stock. The last time a case was sold from Casio was on April 30, 1996. It was to an individual, not a distributor. The CFX-400 case with key pad has two part numbers. The first is 73081910. It was later changed to 73081928, but it is the same part and description. There are two parts still in production and available from Casio that you may want to consider buying. They are the rubber backing seal and the LCD (not the module, just the screen). Good Luck. _________________________________________________________________ Add photos to your messages with MSN 8.

Old CFX-400 cases

by wrawbee＠hotmail.com

Stan, I'm guessing you decided not to trade or sell any of your parts to me. Perhaps you got a better offer or you were offended by mine. I hope I didn't offend you, but if someone offered you a bunch of money for them that's great. If you just decided to hang on to them or something, please keep my email address in case you ever do decide to part with any parts or if you are ever looking for a nice CFX-40 as a backup or replacement. Thanks. _________________________________________________________________ Add photos to your e-mail with MSN 8. Get 2 months FREE*. http://join.msn.com/?page=features/featuredemail

Free: Tektronix RM31A, near Santa Cruz, CA

by tothwolf＠concentric.net

I guess this is slightly OT, but I figure someone here might be interested. I'd love to have the scope myself, but it is rather heavy, and shipping it to Houston would be risky due to the huge number of tubes. (Close to 50 individual tubes IIRC.) This is a rack-mount scope, and it comes with a type CA plug-in. It is located near Santa Cruz, CA just south of Silicon Valley. If anyone is interested, contact me off-list and I will pass on contact information. -Toth

PET 2001 16 N Mystery

by Degnan＠degnanco.net

I wish to pose this question with the hope that there is someone else who has had the same thing happen to them, and/or can suggest a cause/fix.. I have a Commodore PET 2001 16 N. Whenever I try to write or read >from tape (using 1530 drive) the computer freezes up and I am forced to turn off/on. After powering the unit back on, the screen is filled with garbled characters. Turing off/on does not fix. However if I wait a day or two later the computer is OK and the garbled characters no longer appear. I have reproduced this series of events twice and again the computer "fixes itself." I do not want to try again for fear of permanently ruining the machine. Any ideas about what causes this? Anyone had this happen to them?

Emulex SC04 controller... what kind of disk does it talk to?

by CordaAJ＠NSWC.NAVY.MIL

Actually, if I had known you had a bid in on it, I wouldn't have bid against you... Because of my cr*ppy phone connection (no dsl/cable here) I use an online bidding service, so when I find an item, I just register it with the bidding service and forget about it... they email me at the end of the auction to let me know if I've won or lost... But to get back on topic, I can then assume that this was one of those flash-in-the-pan ANSI standards? I've been around quite a while, and I don't remember coming across this one... (and I remember MASSBUS, IPI, SMD, MFM, ESDI, and a handful of other abbreviation...) Oh well, another board for the board-archive/stack... -al- -----Original Message----- From: Al Kossow [mailto:aek@spies.com] Sent: Thursday, July 31, 2003 2:49 PM To: classiccmp(a)classiccmp.org Subject: Re: Emulex SC04 controller... what kind of disk does it talk to? anyone recognize this puppy? -- yup.. ANSI 8" interface I was VERY happy someone outbid me on it when I discovered what it was.. If someone has a paper copy of the X3.101 spec, i'd like to add it to the archives on spies. It appears to be based on the Shugart/Quantum 8" drive standard but on a single 50 pin connector instead of a 50 and 26.

Emulex SC04 controller... what kind of disk does it talk to?

by CordaAJ＠NSWC.NAVY.MIL

Hey guys, Just picked up an Emulex SC04 disk controller (ebay item). I thoughtit was a Qbus SCSI (did a prelim. deja search, and the one note I came across led me to believe this). Apparently I was wrong... the part numberfor the controller is SC0410201-LXB, and (I believe, but I couldbe wrong) this maps to the .pdf on AEK's site: http://www.spies.com/~aek/pdf/emulex/SC0451001-A_SC04C_Jan82.pdf This manual provides a pinout and refers to the disk interface as an ANSI X3T9/1226 interface. This doesn't google to anything useful, however I found an identical pinout list which refers to an ANSI X3.101 interface. Again, I don't recognize this at all. It's definitely not SCSI (if this is the correct manual) and doesn't seem to be SMD... Perhaps I am just blind here... anyone recognize this puppy? For reference, the ebay page w/picture is still available... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2743862622 -al- -acorda(a)1bigred.com
