MIPS RISComputer M/120

by csmith＠amdocs.com

Hi everybody, I have -- in various stages of repair -- three MIPS RISComputers. The model is M/120. I'm in need of an operating system (and maybe even software :) that will run on these. They were given to me without hard drives. Any ideas? Also, can anyone tell me what's the normal amount of RAM for these to have? One of them has two or three (don't remember) RAM boards, and one has five. The third has no RAM, and I wonder whether I could divide the boards between them and still have something reasonable.

ABS type glue / was ASR-33

by Robert_Feldman＠jdedwards.com

There is a new multi-part bonder called "cyanopoxy" that can even glue nylon and "slippery engineering plastics" such as Delrin. It is, however, quite expensive -- $48.50 w/s&h for a small quantity; see www.mrhobby.com. I learned about it in an article in "Railroad Model Craftsman" magazine. Looks good and might work to glue broken switch paddles, but I haven't used it myself. -----Original Message----- From: Craig Smith [mailto:ip500@home.com] Sent: Monday, December 10, 2001 2:41 PM To: classiccmp(a)classiccmp.org Subject: ABS type glue / was ASR-33 Check out a sporting goods store that sells whitewater canoes.

Availability of DSP56K chips

by CLeyson＠aol.com

Hi Carlos Try Dial Electronics, www.dialelec.com, they may be able to get some 56001's, they are resonably priced and don't have a minimum order charge. Unfortunately the rest of the 56k family comes in 144pin quad flat pack, even the 56002. One solution might be get a TQFP to BGA adapter board. The BGA adaptors usually have long enough pins to wrap and solder to. Winslow in the UK may have these in stock. Also, look out for an old style DSP56303-EVM evaluation module. These had pin headers connected to the data, address and control busses. I may have an old one lying around somewhere. Don't bother with the new EVM modules if you need to interface to any hardware - they only have headers for the control bus and 8-bit host port. Note: The 8-bit host port is a slave port only and needs to be driven from external processor. I've been using the 56300 family for quite a while now. The 24-bit instructions let you do one arithmetic op and two data moves in one cycle. The DMA channels allow you to move data without interrupting the core. You also get a lot more internal memory with the 563xx parts. My personal preference is to run these processors using internal memory only. Just use slow 8-bit flash to load programs. It saves having to use fast SRAM and you can do all of your I/O with fast serial links if need be. 56303 - 4k program, 2k X and Y ram. 3.3V core and I/O. I/O is 5V tolerent. Speed 80-100MHz. 144pin TQFP 56309, 20k program, 7k X and Y ram. 3.3V core and I/O. I/O is not 5V tolerent. Speed 80-100MHz. 144pin TQFP or PBGA (Plastic Ball Grid Array) package. 56307, 48k program, 8k X and Y ram, or 16k P ram and 24 X & Y ram 1.8V or 2.5V core and 3.3V I/O. Speed 100-160MHz. BGA package only. 56307 also comes with an independent Co-processor on board. All the Motorola tools are free even the gnu C compiler. I used the C compiler once and didn't like it. It produced slow code and didn't even support a fractional data type !! Not much use if your processor work in fractional arithmetic. I do all of my DSP programming in assembler. Alternatively try Texas or Analog Devices. Chris

That's the driver for the DMB32. To hide it from SYSGEN it just needs to be renamed: $ RENAME SYS$COMMON:[SYS$LDR]SIDRIVER.EXE SYS$COMMON:[SYS$LDR]SIDRIVER.OLD But just in case, it might be worth checking that you don't have more than one version lying around: $ DIR SYS$LOADABLE_IMAGES:SIDRIVER.EXE Normally I would suggest purging down if multiple files are kicking around, but since this system is all you have, I'd go with renaming all of them and keeping the version numbers the same i.e. $ RENAME SYS$COMMON:[SYS$LDR]SIDRIVER.EXE;33 SYS$COMMON:[SYS$LDR]SIDRIVER.OLD;33 or whatever. The other WAN device drivers you won't care about are SJDRIVER, SLDRIVER, SFDRIVER, SEDRIVER, ZTDRIVER and ZWDRIVER ... actually I'm sure there are more, I've just mislaid my list! If SIDRIVER is out of date I guess that the rest will be too. However, I assume that SIDRIVER is getting dragged in because SYSGEN found a DMB32? Antonio

Free DEC stuff in Milpitas CA

by bob＠jfcl.com

I have the following mostly (but not all) DEC stuff to give away FREE. All you have to do is pick it up in Milpitas CA (next door to San Jose). * A VAXstation-2000. No disks (you'll need to find an RD5x/3x for it). No guarantees of condition, either, but then it is free :-) * A VAXstation-3100/30. No disks (but you can use almost any SCSI drive). No guarantees of condition, either, but then it is free :-) * A Sophia Systems SA-2000 8-bit ICE. This is a self contained CP/M machine from the early 80s in a "luggable" case something like the KayPro or Osborne. Includes SA-DOS boot diskettes but no pods (it boots and runs just fine with out them). * A DECmate-II RX50 system (no hard disk) WITHOUT the 6120 CPU chip. System unit only - no monitor or keyboard. * About half a dozen DEC orange binders (empty). * A MicroVMS (VMS v4.x) manual set, in orange binders. * Most of an OpenVMS v7.x manual set (perfect bound). * A padded, sound proof printer enclosure for a 14" dot matrix printer, including a fan. I only read this list in digest form, and I'm way behind on that, so please write to me directly if you're interested in anything. Bob

Availability of DSP56K chips

by cmurillo＠emtelsa.multi.net.co

Hi everyone; It's been a while since I last coded stuff for robot control. The last time I did that, the DSP56K (dsp56001 in particular) chips were readily available. Now I need to develop a new platform for research purposes and I am finding that the once ubiquitous dsp56k chips have been eol'd (end-of-line'd in motorola parlance). The suggested replacements are the dsp56301 or 303 chips, which are code compatible, have 24 bit addressing (instead of 16 bit), run at 80MIPs instead of 20, and have all the glue logic for PCI or ISA interfacing built-in (dsp56301, which makes sense in my application because the robot supervisor will be a Linux server receiving commands from robot application clients over tcp/ip; the dsp will be a slave that does the low level yet massive number crunching stuff). So why don't I just go and choose the newer parts? Several reasons: 1) I'd prefer to go with unix-based free software tools. There is a56k and gcc56k for the dsp56k. While the dsp56.3k is supposedly code-compatible, I am sure that some tweaking would be required to make these tools work with the new family, and compilers are not my area of expertise. 2) The older parts have roughly 100 pins and can be wirewrapped, the new parts have 192 pins and require modern pcb design and production techniques, which are outrageously expensive in this corner of the world. I am not comfortable wire-wrapping a design that runs at 80MHz instead of 20. 3) From experience, I know that 20MIPS is enough for the task at hand. So, I am faced with a familiar problem; an old part that will do the job in a simpler design is no longer (readily) available; there is a new, better, faster part, but there aren't as many software goodies to go with it, and the hardware design tools and fabrication are more expensive. The key issue is the present availability of the older parts. I've checked some places and they seem to actually be out of these chips. So my question to the list is: do you know where to get dsp56001A chips? Or better yet, do you have some that you don't plan to use? carlos. -------------------------------------------------------------- Carlos E. Murillo-Sanchez carlos_murillo(a)nospammers.ieee.org

Availability of DSP56K chips

by CLeyson＠aol.com

Carlos Sorry I got carried away. If all you need is a slave processor and 20Mips, then the 56303-EVM is ideal. You get 64k x 8 flash, 32k x 24 fast SRAM, a 16-bit stereo codec and a pin header for the host port. Also included is a 56002 which acts as an RS232 to JTAG interface for Domain Technologies Debug-56k debugger, also free from Domain Technologies, www.domaintec.com. Chris

It was shipped, I think, with both 3.5 and 5.25" high-density floppy drives. I just found another 3.5" floppy that works in it on Saturday night. I got no manuals, no software (other than what was extremely messed up and left on the drive), and a disassembled machine. The machine is now in more-or-less good shape. I need to pick the tumbler keyboard lock. For now I've just disconnected it. (Or find a key that works) I should also replace the power adaptor I've got plugged into the floppy drive, since it's also got a signal cable adaptor that's not being used. :) As I was saying, the installation was pretty botched by the time I got it. It boots -- thinks it runs MS-DOS 3.2 -- and that's really about it. I believe the CPU was intel 286. It has a "Tall Tree Systems" JRAM card and JLaser 3 (I think) daughterboard. a 20MB MFM (or RLL?) 3.5" half-height hard disk. (Miniscribe, I believe) It also has (...and this is the reason I rescued it, even though it is an intel machine) a really odd graphics adaptor with a 15-pin (two row D-shaped) connector that drives a full-page monochrome (white) EGA monitor. That's pretty much all I know about it. Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

It's less difficult than you think. But I know just what you mean, VMS is just trying to be too clever :-). But you can do binary copies, just do this: $ MOUNT/FOREIGN/BLOCK=512/RECORD=512 MUC6: $ COPY MUC6: FILE.001 $ COPY MUC6: FILE.002 Now you don't know off hand what the block size on the tape is. I think, if you pick a block size smaller than the tape's, you will receive error messages. Experiment with it a little bit. Analogously, copy as many files as you can, for you don't know how many files the SAVE EEPROM command has written. -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Several Apollo computers for free - Raleigh, NC

by cdrice＠pobox.com

My mail to this list keeps bouncing, but I'm still getting the digests. I haven't seen my message in a digest, so I'm assuming no one else saw it either. So, here we go (again) -- sorry if everyone gets this three times... -------- Original Message -------- I've been following this list for some time; however, recent family emergencies have required me to give up most of my hobbies for some time, and likely in the future. I'm also having to move rather quickly across the state and sell my home in Raleigh; I'm selling and giving away a number of things that I just don't see myself having time to deal with in the near future. Among them are several Apollo computers, and stack of misc. hardware (token ring parts and cables, misc. video and i/o cables, etc). and a very large stack of documentation. There are free (unless you feel compelled to make a donation to the feed- a-Chuck fund). :) >From my notes (I do NOT absolutely guarantee this is accurate): - 3500 with: - 170MB HD - SMS/Omti controller - mono video card - 19" mono monitor - 32MB RAM - 3COM 3C505 - DomainOS 10.4.1 - 5 1/4" disk drive - 3000 (unknown contents) - 3500 (unknown contents) - 2500 (unknown contents) - Another CPU (maybe a 4000?) with color card and monitor; I don't have all the specs with me, but it was fully functional when I last shut it down. - Apollo token ring - Isolan multiplex repeater - Lots of misc. parts (cables, keyboards, etc.) - Lots and lots of books; some still in original shrink-wrap **I WILL NOT SHIP THESE ITEMS.** Sorry; they're just too heavy and bulky for me to package and ship; I just have too much else going on right now. With everything going on, I STRONGLY prefer someone take everything. I will not be able to take the time to go through any of this and pick out parts that people want. I am in Garner, NC (just south of Raleigh). I can provide exact location and directions upon request. I am usually only in town on Thursdays and Fridays. Please email me if you are interested and we can work out the details. Please help me find a home for these guys; if I don't find a taker pretty soon, they'll have to go to the recyclers. - Chuck -- | Charles Dee Rice ------------------------------------- cdrice(a)pobox.com | | "You know how it is with me baby - You know I just can't stand myself | | It takes a whole lot of medicine, darlin' | | For me to pretend I'm somebody else." |

Being a PET user from way back, I always liked the Commodore drives from one particular aspect - they were intellegent peripherals.

The thing I did *not* like about them was that they were scorchingly expensive. By the time I could afford a PET drive, nobody cared anymore.

overclocking older processors

Anybody ever done that? I've just sent EK-78032-UG, basically the 78032 User Guide over to DFWCUG. You can see the gory details once it arrives and they put it up. In the meantime, from Appendix A, clock period is variable from 25ns to 250ns i.e. 40MHz to 4MHz. It specifically states (somewhere) that the part will *not* work down to DC. The clock should be held in the high and low states for 16ns each, so even with infinitely fast rise and fall you cannot do better than 32ns and stay reliable across all parts and all temperature ranges. Now if you are willing to restrict the temperature range and hope to work on just *most* parts, who knows :-) Tweaking a MicroVAX II won't buy you much. I doubt you could bump the clock by much more than say 20% without something going horribly wrong. And the uVAX II is a fairly well balanced system: the memory cycle is just about right for the CPU (I think it works out that the CPU cycle time matches the memory cycle time - hence no need for cache). So if you up the CPU clock, you need to find some way to speed up the memory otherwise you don't even see your modest 20% gain. Antonio

iPDS questions

by healyzh＠aracnet.com

I'm sure glad to see the list is back up, I originally tried the following message on Tuesday. I still don't know anything more about the system. Unfortunatly it's been raining really hard around here since Tuesday, so the system is still sitting at work, and I've not really been able to examine it. Zane I'm still a little shocked. I just found a working iPDS system, complete with documentation and some software. Unfortunatly I don't think a lot of it is still readable. I did get the system to boot and pass all diagnostics. I know nothing about these beasties, from looking at the doc's it's obviously i8085 based with 64k RAM. It's got a single 5 1/4" floppy, and it's in a case slightly smaller than a Kaypro II. In the area behind the CRT is a storage area for two pods that each handle two different sizes of PROMs, these plug into a hole in the right side of the case. What on earth filesystem are the floppies? Are any kind of software images available to replace the dead floppies? Is there any software to read and write to the floppies from MS-DOS? Basically the main thing I'm interested in is the systems ability to read and write PROMs. I wouldn't mind being able to use this to support my DEC hardware :^) Zane -- | Zane H.

PDP 11/34 Console & cards

by fcharp＠rogers.com

Hi, I have sitting on my shelf a PDP 11/34 working unit rescued from the recyclers. The system was operational when decomissioned. Caveat: no power supply. So the pieces or the whole are up for grabs, shipping costs only. I thought they may be of interest to the right people, since most of the boards were original DEC. I also have a CD-ROM full of DEC maintenance and service documents for the PDP series. Any interest in that, ask for details. Be aware that I live in Ottawa, Canada. Here is the list of cards found in there. I am not sure it is complete, because I may have listed only the ones I could actually recognize. PDP 11/34 CARDS DIGITAL M7762 RL11 U RX01 floppy disk controller M7856 DL11-W U SLU and realtime clock M7859 U 11/34 programmable console interface M8256 RX211 U RX02 floppy disk controller M8265 KD11-EA U 11/34A processor data paths M8266 KD11-EA U 11/34A processor microcode module M8267 FP11-A U 11/34A floating point processor M9202 U UNIBUS connector, inverted (M9192+M9292 assembled M9202 1" apart with 2' cable) M9312 U Bootstrap and terminator module OTHER Dataram Corp U 256K DRAM board The system was obviously well cared for and was not even dusty. The console board is the one that includes an Intel 8008 processor. The system case and front-end are impeccable. I don't collect PDP equipment, but I hate to see a nice system go to the junkyard. At the same time, I need to make room for other masterpieces in peril. Cheers, Frederic Charpentier

All, With regards to the DEC CDs, I will extract the titles of the manuals (about 200, I think) and post them. There are too many service bulletins and the titles are all numbered, so I won't have the time for that. For those who requested the CD's, I will let you know when they are ready -- some time this week. I am not sure that mounting images of the CDs on ftp is a good idea (I don't know what the copyright issues are there), but I don't mind making copies for those who want them. ...oh -- and yes, I will let you know about the stuff that I would like to get pretty soon... :-) Cheers, Frederic Charpentier

Remington Rand 409 (this already has been posted!)

by ae＠alum.mit.edu

I am helping to gather original documents and/or artifacts concerning the Remington Rand 409-series computers for the Remington Rand 409-series museum being set up in Rowayton, CT. The models of interest are the 409-2 and the 409-2R. These are tube, punch-card, and programming panel machines >from the 1950s. We are interested in documenting the location of all surviving artifacts, but also would like to acquire particularly interesting items by donation or purchase. We are looking specifically for anything related to the programming of these machines, such as the programming panels, programming manuals, or the programming jumper wires. Photographs or drawings of programming panels (originals or reproduced in third-party publications), with or without programs wired on them, also would be of interest. If you have any of the above, or have more general items such as Remington Rand brand computer tubes or punch cards, whether or not you wish to sell or donate them, please e-mail me at: egendorf(a)mit.edu.

11/44 power problem... (Oh, not again...)

by DSEAGRAV＠toad.xkl.com

Same machine, new problem. ^_^ Whilst out in the garage playing with the 44 (which I still don't have an OS for...), my kid sister and one of her friends come out to the garage to smoke. (They're not allowed to smoke in the house.) Anyway, while the 44 is running, her friend says, "Wow, that's loud!", to which Monica replies "This one's louder!" and turns on the KS10... You know what's coming. And we had christmas tree packages and such all over the garage, too, so navigating the garage in the dark was real fun... (For those who didn't see it coming, the garage breaker went...) Anyway, after resetting the breaker, waiting for the VAX to reboot, checking that the KS10 was still in working order (I wouldn't be mailing if the KS10 was broken. I'd be busy burying my sister. ^_^) and putting back all the boxes I stepped on or knocked over, it was discovered that the 11/44 no longer powered on. The power control lights are on, the RX02 and SCSI disks inside the case work, but the BA11 (Is that the right part?) will not turn on. When you turn the switch on the front panel, nothing happens. No click, no fans, nothing. The breaker on the back of the BA11 did not trip. I turned it off and back on, nothing happened. I ran the AC power checks in the manual and nothing happened. I checked the front-panel wiring was still connected, it was. I pulled and reseated the front-panel control board in the UNIBUS. Nada. It looks like it should be working, it doesn't smell burnt, and I opened the top of the BA11 power supply and looked inside, and it looks really scary (what, with the THIS VOLTAGE WILL KILL YOU stickers and wires thick as my fingers and whatnot...) but it doesn't look burnt. Is there a hidden switch or fuse or something in there? That's what it looks like... Failing that, someone got directions for checking out an 11/44 power supply? -------

The same concept is used for the Mac's and their PC cards. The Intel chip is placed on a card, and it runs independant of the mac (but shares some features like drive controller, stuff like that). You swap between them with a hot key, and you can have things running on each (ie: start something heavy on the Mac, swap to windows/dos/whatever OS you are running, it is a true Intel compatible setup, and run things there.) Swap between as much as you want, each will continue to run, being blissfully unaware the other is there. Connection between the two is nice, you can have shared folders between them. The Mac will view it as a folder, the PC will view it as an additionally available drive. And you can cut and paste between the two. Very nice setup, too bad Apple abondoned them, and stopped upgrading the driver software, so they don't work too well past System 7.6.1 (they will work under OS 8 and 9, but some problems can arise) -chris <http://www.mythtech.net>

PDP 11/34 Console & cards

by fcharp＠rogers.com

All, Well, that was quick. The system is spoken for. Thanks to all for their interest. Regarding the DEC service CD: in fact, there are 2 CDs. They are full of manuals and service stuff, BUT they cover more recent equipment than the PDP. The last dates on the CD are 1994, which says that there is a lot of VAX-related material on the discs, but not much with regards to PDP. My apologies. Anyway, I already had a couple of requests for them, so I guess I'll be giving the ol'burner a run for its money. Cheers, Frederic Charpentier

Apples and Oranges, but Primes have an A/C distribution box in the back that the big round A/C plug goes into... this whole box removes from the chassis, and when disassembled, reveals a fuse inside along with something that looks like an EMI filter. The fuse is replaceable without soldering... ...but this is a Prime, not a PDP-11/44, but I'd look for something similar... -dq

Well, after all the talk about a MicroVax II BA123 on the list lately, I managed to unbury mine. It appears to be all original except for 2 hard drives that may have been added as an upgrade. All the boards match up with the DEC sticker with handwritten board numbers. It has the standard cpu board, what seems to be a 2mb ram board, a serial interface board w/ 8 ports, and the standard scsi and tape interface boards. It also has some sort of loopback board in the upper 3rd slot. Does anyone have a link to reference info on these boards? I'd like to find a pair of 8mb ram boards and a network interface for this thing, so I can put it back in service for open source software development/testing. I don't know the part numbers for these boards, so any extra info would be great. I'm also looking for the door that covers the front control panel, as this machine seems to have lost its door at some point before I rescued it. If anyone has any of these parts laying around, please drop me an email. I'm more then willing to pay shipping. I really don't think I have much of anything anyone here would want as a trade, so I'm willing to pay for the parts too if required. Another interesting tidbit about this box, it still has its inventory sticker from NASA, and it orig cost good old uncle sam $22,000+. Anyone else wonder why they didn't have it outfitted with a network interface of somesort, especially with it costing that much already? -Toth

My former boss at Software Productions (we wrote kiddie software for home computers under the Reader's Digest label) put a story in an early version of the docs of how he fired up his Apple ][ to run CP/M and the disk drive made odd noises... he took it in for service and the tech extracted fragments of a Peanut Butter & Jelly sandwich.

I just dug out a couple iPDSs out of my storage locker that I am getting ready for sale. I may be interested in some copies of the documentation. I also have some disks but have not checked their condition. You are right that they are 8085 systems. Besides EPROM programmers there was also an EMV 51 emulator pod for IIRC debugging the 8051. There are also external floppy disk drives that daisy chain to it. It also ran CPM. I believe Fred's Xenocopy program will copy diskettes for it. IIRC they are standard 360K DSDD drives.

Houston Classic Computers was {Off-Topic: Re: Anyone have a MicroVax II in a BA123 available?}

by msell＠ontimesupport.com

I don't know of a formal (or informal....) classic computer user group in Houston, but I would love to participate in one. I know that there are several of us in Houston. I met with David and Mitch recently; very nice people. David has a real neat collection of older "personal" computers and some other Unix-class boxen as well. Obviously there are more of us, an informal gathering would be neat. - Matt >Now, to change the subject of this thread, does anyone know of any >"classic computer" user groups in the Houston area? > >-Toth Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/cgi-bin/mojo/mojo.cgi "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler Many thanks for this tagline to a fellow RGVAC'er...

Anyone parting with a Wyse 60

by mythtech＠Mac.com

Does anyone have a Wyse 60 they want to part with on the cheap? (working only please... I have a dead one thanks) I tried buying one on ebay a few times, and each time, either they were in horrible condition, or went above my price threshold, or I got "ebayed" at the last second by someone outbidding me. I would prefer one in the NJ area that I can drive and pick up as cost is my #1 issue, but if total cost (buy + shipping) isn't too bad, I will accept shipped ones. I might have stuff to trade, but most everything I have that is available to be parted with is PC related, which A: isn't as popular here, and B: isn't as hard to get as other systems. I do have a C64 or two (don't know functional condition), maybe some other stuff (like these Zebra 2500 manuals I keep tripping on) If you have something in mind, let me know, I will see if I have it. Thanks -chris <http://www.mythtech.net>

Badtrans

by philpem＠bigfoot.com

Hi All, I've noticed that a few of you have been chatting about Badtrans - according to Symantec, if you drop the underscore from the "From:" address, you should end up with the user's actual e-mail address - if the virus chose to use the actual address... I've picked apart the message source and what it does is quite sneaky - it uses an IFRAME to load the virus and also uses MIME-headers-within-MIME-headers... A few of the regulars on alt.comp.virus might want to elaborate... It's a crafty little bugger - it even installs a keystroke logging trojan... Anyone remember the so-called "Sexyfun" or "Spirale" virus (it's real name was Hybris) - it came in an e-mail from hahaha @ sexyfun.net and could update itself over the web with new "plugins"... One of which displays a _huge_ hypnotic spiral on-screen... Sophos put a screenshot of it on their website (www.sophos.com). Later. -- Phil. philpem(a)bigfoot.com http://www.philpem.f9.co.uk/

Actually, I don't like the old style optical mice at all. I like this one because I think the older optical mice are hard to find. And on top of it, this was manufactured for use on the Jr - it wasn't just a run-of-the-mill PC mouse, it had two funny connectors specific to the Jr. (One for serial, and one to take power off the lightpen port.) All of that makes it special. My original machine had an MS bus mouse with a roller. Quite a different animal to use. The new optical mice are only vaguely related to the old ones. They don't need the pad or anything. I haven't used one, so I don't know if they are any more usable.

Dataproducts printer inteface

by steve＠airborn.com.au

Sorry for the repost... but has anyone heard of the (old) Dataproducts printer inteface? It was also called the Line printer interface, and was used on other Brands besides just Dataproducts. Basically I know it uses differential signals - otherwise similar to centronics - but I would like to find out some details. I have the Pinout: http://www.hardwarebook.net/connector/parallel/dataproductsdsub50.html I would really like to find a description of the "Demand" signal and the polarity of "Strobe" and "OnLine" I would like to know the levels (I presume they are TTL) If anyone can help me out, perhaps I can respond in kind by giving them the final result - a circuit for a Centronics-->Dataproducts interface. steve(a)airborn.com.au

Bubble sorts have their place (was: FLUKE?

Back to the description of the bubble sort that Wirth had in his book (the book is "algorighms + data structures = programs," for the curious), he suggests modifications to a bubble sort: Always remember the position of the last switch that you've made. You can start/end here next time. (A similar thing was mentioned in a previous mail by somebody) Alternate the order of the sort going right-to-left one pass and left-to-right the next. That takes advantage of the fact that a number that's incredibly far out of place will tend to move further if you're sorting towards its proper place. (In other words, it's as you say, but assuming that we don't know the order of the data, so the sort can be generic and still be more efficient) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '
