hp2114 basic

by Tim＠rikers.org

From what I hear, the system I used was not one of the TSB series. I'm still interested in trying it out. I don't see binaries online anywhere. Can someone point me to them? I never did any admin on the systems as a student. I only had access using BASIC. I have booted up SIMH with the hp basic stand alone, and it's similar but lacks some features our system had like string variables. http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs I see on jeffs site the source tapes for 22255 "Four user BASIC". Perhaps this is the system we were running? 2 CRTs, one ASR-33 and a card reader would mean 4 users, correct? http://oscar.taurus.com/~jeff/2100/hpbasic/index.html Anyone willing to give be instructions on how to get the files assembled? I would think I'd load something like the "extended assember" via PTR: http://oscar.taurus.com/~jeff/2100/siotapes/extasmb.abs jump someplace? and then feed in each of the basic tapes on the same PTR? My experience has been with Linux on all kinds of hardware, from x86 servers and desktops to alpha, sparc, ia64, mips, ppc, sh3, and many arm systems. Most recent work is with ARM boxes. I was deeply involved with the SHarp Zaurus release while working at Lineo (or Embedix, or Metroworks, or whatever they call themselves now). I have simh up and running. Not the same without the blinking lights. Perhaps Jay's emulator will have blinking lights? We did a version of VNC for the Zaurus that had a "skin" which was a scanned image of the device. I envision the same interface on an emulator. click the buttons with the mouse, turn the key to lock/unlock, Would be nice to have a tape reader with audio and perhaps a mag tape too. ;-) There used to be some internet accessable simh access systems running. Are they still? I notice that simh just loops like the actual machine would. This means it eats up 100% cpu all the time. Seems to me that should get hacked somehow to detect "idle" states, and select() someplace for a short ammount of time instead of looping all the time. If I ran the simulator on my Zaurus it would suck the battery dry in no time. We can't have that can we? ;-) Well, thanx in advance for the help. I look forward to trying out the 4 user basic environment and see if it's what I recall. -- Tim Riker - http://rikers.org/ - TimR at Debian.org Embedded Linux Technologist BZFlag maintainer - http://BZFlag.org/ - for fun!

TCPSER4J Modem Emulator development

by brain＠jbrain.com

To address some limitations in my tcpser modem emulator (http://www.jbrain.com/pub/linux/serial), I've been working on a new version that is Java based. Firstly, comments about any hate of Java should be directed to /dev/null or similar :-) tcpser4j is a piece of software that runs on a PC/Mac/Workstation and turns a regular rs232 port into an emulated Hayes compatible modem. Instead of dialing out over phone lines, this modem uses TCP/IP for the connection. tcpser4j can handle both incoming and outgoing calls. It is most useful to place vintage BBS systems online as telnet BBSes. The original version of tcpser was a single 'C' codebase, but to get Win32 support I needed cygwin1.dll. That is a problem at times, and there are a number of older versions of the DLL out there that do not work with the app. As well, baud rates less than 300 seem to be non-functional in the DLL. I can't legally redistribute the DLL in my archive either. Moving to Java addressed those issues, and it also allowed the codebase to become more dynamically loadable, or reloadable. The new version contains the following features found in the original: o Multi-platform support o Support for all normal and extended Hayes AT commands, including multi-command strings o Proper S register support, including changing line terminator, linefeed char, guard time, etc. o Correct AT command response codes, including abbreviated numeric codes and Hayes Smartmodem limited response code emulation. o Tracing abilities (see what is being sent on the wire) o Phone book aliases (alias 555-1212 to servername:portnumber) o Multi-line support (multiple "modems" listen on one IP port, like modem pool) o Proper DCD support (with modified null modem cable) o Very good Hayes modem emulation o Inbound and outbound call support o Support for sending text files or raw text to local and remote sides for events like BUSY, ANSWER, TIMEOUT, NO_ANSWER, etc. o Support for inverting the DCD line o Proper support for +++ Hayes escape sequence o Support for handling NVT sequence negotiation when "dialing" telnet servers The new version hopes to better the original in a number of ways: o Java codebase, can be run on any platform with a 1.2+ JRE o Uses the RXTX Comm Library, available for most platforms. o Extensive logging flexibility. Users should be able to cater logging to their heart's desire o Better support for AT command set. Default S register setting and querying now supported, for example. o Multi-modem bank support (configure 2 modems on 1 port, 3 on another, etc.) o XML based configuration file easier to use than command line switches o Phone book aliases now loaded from file. o Multiple Phone books, with phone book delegation. Modem has a modem book, which checks pool book if no results. pool book checks master book if no match found in pool book. o Support for remote administration GUI o TCP232 option. Connect to the server via TCP/IP port and issue AT modem commands. This is best used with an emulator like VICE that emulates a rs232 interface by conecting to a TCP/IP port. It can also be used to test modem operation. DCD operation is not supported in this mode. o Remote232 option. This allows one to use RS232 ports on on the local machine. If your BBS or vintage PC is by another PC, but you want tcpser4j to run on a server, use this option. the RS232 port need only be on a machine reachable via TCP/IP, so it could be across the house, the state, the country, or the world. All control lines are preserved in this mode. o captive modem support. If configured, soft-modem will listen to IP port and real modem. This will allow existing dialup BBS systems to add telnet option while preserving dialup user support. In this mode, if telnet access is active, captive modem will be placed off-hook, and will be placed on-hook when telnet user logs off. Outbound calls will also be routed, so atdtjbrain.com will go out over IP, while atdt431-7754 will use modem. (this is still under development) o Better support for +++ sequence timing. o Support for extended error code reporting (i.e.: "NO CARRIER (Server Refused Connection)") o Support for adding new modem commands to better emulate specific modem variants I'm pretty much done with the base code, and am looking for some folks who would be interested in helping to test this codebase in some situations with different vintage platforms and send bug reports. As it's an all-new codebase, I need to do a shakedown. Initial testing has been good, but I only have so many test scenarios here. I'm also interested in ideas folks might have. Some have asked for hooks to add a chat room in the unit for folks who get busy signals when dialing in. I'm looking into that option, and some others. Most will be support via dynamic classes. Finally, I'm looking for someone to help with the Remote GUI Administration component. The codebase is available at: http://www.jbrain.com/pub/xplatform/serial/tcpser4j-2.0alpha.zip. Windows users need only unzip and execute run.bat. Other platforms need to install the appropriate RXTXComm JNI library (http://users.frii.com/jarvi/rxtx/) for that platform and tweak the run script to suit. Since I can redistribute the RXTX codebase, I may add the various libraries in a later release. Please send run scripts for other platforms. Notes: I preloaded all of the telnet BBS systems I know of into the master phone book. Please help me add to the list. As well, I created my own protocol for encapsulating serial line status into a TCP/IP datastream with the serial data. I had once saw another application that provided remote serial ports, but was unsuccessful in finding a current reference. If someone has a link and the existing protocol will work for this project, I will change my code to use the existing protocol. I have not prepared a proper README file for tcpser4j as yet. Please use information from the current tcpser project archive, or email me if you have trouble. I have tested the IP232 port option with the WinVICE emulator configured to send serial data to a remote IP port. VICE 1.16 has bugs with TCP/IP serial option, but 1.15 works. However, I have not yet been able to test the ACIA IP emulation in 1.15, and the user port emulation fails if custom RS232 routines (the George Hug routines, for example) are used. Normal KERNAL RS232 works fine. Jim Brain -- Jim Brain, Brain Innovations brain at jbrain.com http://www.jbrain.com Dabbling in WWW, Embedded Systems, Old CBM computers, and Good Times!

program to print out ASCII renderings of punch cards and/or papertape?

by ethan.dicks＠gmail.com

I've been wracking my brains and googling for most of an hour... ISTR there _used_ to be a program that shipped with UNIX (at least BSD-flavors, if nothing else) that could take a string as a command line arg, and print either a punch card image or papertape renderings to stdout. Does anyone remember the _name_ of this program? Thanks, -ethan

Sparc5 bits wanted

by witchy＠binarydinosaurs.co.uk

Folks, (eep, is a Sparc5 on topic?!) While clearing out the soon-to-be dining room where all my stuff has been stored for the last couple of years I found a Sparc5 that I'd completely forgotten about. It's been completely robbed of bits that I can see - memory, floppy drive, CD, HDD - so what's the minimum I can get away with before at least powering it up to see if it works? The only spare memory I've got is PC100 (may even be PC66) 168-pin DIMMS. Can I use a serial console on it or do I need a 13w3 monitor cable? The HDD looks like it's a standard SCA-80 connection....keyboard and mouse are there but I hope I don't need one of those foil mousemats! Assuming it does work does anyone have a floppy and CD spare for this thing?

David, After close examination of the pictures, I am certain that the PDP-1 shown in the pictures is in fact the one at the Computer History Museum. You can even see the purple cubicle walls (left over from SGI's former tenancy of the building) that are used as a backdrop for the Visible Storage exhibit currently on display. Also, the picture of the inside does not look like a production machine -- it is almost certainly a photo of the prototype PDP-1 also owned by CHM. Others have noted that the photo of the G-15 appears to be a fake composite. I admit that before realizing this, I sent serious inquiries to both parties advising them that they were sitting on treasures worth big $$$$ and would be well advised to preserve them. --Bill

I'm in another hobby, science fiction fanzines, where we just lost one of the most significant collections of the last 50 years. And all because the collector didn't write it's disposition exactly in his will. He left most of his estate to his church. The fanzines were left to a University collection. He mentioned this is letters and conversations - but not in the will. But probate ruled that the church gets everything since it wasn't in the will. The church wass fighting to keep the stuff because they smell big money. So the collection now is lost to the group that would appreciate it most. I know of two major collections of science fiction lost the same way. One of them was original art worth hundreds of thousands of dollars. Is your collection going to the dump? Will your kin know what to do with it? Will the books and tapes be tossed? If you value the effort you put into it, protect your collection. Write it up - talk to your heirs. Billy

It also made me think there could be >opportunity in aggregating and searching these giveaway mailing lists. My wife monitors the list for my county... and I get the feeling that a centralized list would work against the point of Freecycle. I have the strong impression that anyone sucking up the goods to resell or otherwise do anything other than fill personal use (and this would border on collectors hording items as well), is not what the freecycle movement is all about. So a cental list, that a reseller could monitor and have the resources to snatch everything of value quickly, would be seriously frowned upon. By keeping the lists smaller and more local, it helps bolster the general idea of being a good neighbor. That said, I do watch for computers of interest myself (I haven't snagged any yet however). But I also give back, just Tuesday I gave away an unneeded queen size box spring via Freecycle. And last night I replied to someone looking for a free PC monitor (but haven't heard back, so I gather they got a better offer then the 14" I have available). -chris <http://www.mythtech.net>

In searching for radio gear, I ran across this URL and thought it might of some interest here. I don't recognize it, but it looks like it might be some older computer stuff. http://www.geocities.com/heftyharry/OLD_COMPUTER_SALE.html

I favor 13 months and a yearly leap day. So how would you deal with the fact that a tropical year will *never* divide evenly into days no matter how you twist and turn it? In my calendar I've addressed this problem at its root: instead of starting with the day as the basic unit and trying to pack days into years like other calendars do (doomed to failure because of the above), I start with the year as the basic unit (actual astronomically determined tropical years starting at Ostara, the vernal equinox), divide the year into dates mathematically (without regard to actual solar days), and then *map* days to dates as a separate function.

OT: Sheet metal and UNF screws (was Re: PET and the IEEE-488 interface)

What do you mean by "#4 copper wire"? 4SWG, which is just under 1/4" diameter? 4AWG, which is somewhat slimmer? That might be "wire" to the company that runs the mill that makes it[1], but it would be "copper rod" to most of the rest of us. Try a model engineering supplier. Or do you mean insulated cable? That would have a cross-sectional area of between 21mm^2 and 28mm^2, depending on whose wire gauge you used, and would have a current capacity of something like 150 amps, continuous, in an enclosed space (like a conduit). Almost double that in free air, more for intermittent use. Try a welding supplier, and ask for the cable used for earth clamps, or buy a cheap pair of jump leads. Or do what I did, and twist 3 or 4 thinner cables together. I have a cable that will run about 350A-400A, good for a fairly decent spot welder. [1] I once got some 3/8" square silver steel from the local wire works. They called *that* wire, too. -- Pete Peter Turnbull Network Manager University of York

LOL. Brilliant. Saw a nice article today that calls cellphone owners to help astronomers to receive signals from the Huygens space probe (now on the moon Titan of Saturn). Here is the (free) translation: AMSTERDAM - Astronomers are asking the help of Dutch and Belgium cellphone owners to receive the extremely weak radio signals of the European space probe Huygens. Huygens is since 14th of January on the Saturn moon Titan. Allthough it was thought that Huygens after its descend on parachutes would only survive a few minutes there are clues that the probe is still active. Astronomers all over the world want to pick up Huygens' radiosignal as soon as possible, because any day could be the last that the probe still has sufficient energy. In order to receive the weak radiosignal astronomers call in the help of the people. Using cellphones, measurements can be done because cellphones are sensitive to radio signals. Cellphones communicate via repeaters with telecom satellites. Since these satellites reflect the signal back to the earth surface, groundstations for satellite communication, but also radio astronomers observatories, who have often bigger dish antennas, can receive the weak signals. By cooperating all cellphones, Holland and Belgium can form a gigantic radiotelescope. If people go on to the streets and aim their cellphone between 12.30 and 13.00 hours in east direction, those tens of thousends cellphones work together as one big radio mirror. The weak Huygens signal reflects via space back to the east of our (Holland) country where it can be picked up by out VLA synthesis radio telescope. The amplified signal will enable this radio telescope to receive the Huygens signal loud and clear. It is hoped that astronomers can find out what happened to the probe in the last few months by this amplification. <end trandslation> Here is the URL to the article (in Dutch of course) http://www.nu.nl/news/504049/81/Zwak_signaal_Huygens_opvangen_met_mobieltjes .html keep your eyes open! - Henk. > From: "Gooijen H" <GOOI at oce.nl> > Subject: RE: searching for a set of RL02 slides > > > > Damn, I've been fooled by Edward! <grumble-grumble> > > Today is April 1st, and that is the day that everybody tries > > to fool everybody in Holland.

As it is, it's gathering dust. It varies very slightly from maker to maker and even batch to batch, so if it's that critical you'll need to measure it. Indirectly, the 802.3 standard says 0.78; my tables show Belden 9880 VF is 0.78-0.82, attn 1.3dB/ft @ 100MHz, 2.8dB/ft @ 400Mz, 4.5dB/ft @ 1GHz.

To be picky, DIX != thick Ethernet, or more exactly DIX != 10base5. 10base5 uses thick coax but it works slightly differently to DIX. Yes, they use AUI cables and transceivers with a DA15 connector with that horrible slidelock, and they use vampire clamps on some of the taps (last time I fitted one was for a demo two weeks ago), but the "Ethernet" cable is the thick coax, with N connectors. > PS: That connector looks odd to me. My coax net has BNC T's on it and > a reflector on the end. Maybe we're not talking about the same > things? You mean a terminator. And the BNCs are thinnet, aka cheapernet, 10base2. Same speed as 10base5, but shorter (185m per segment instead of 500m), and with fewer allowed active connections per segment, and different rules about spacing the taps, which are BNC T-pieces. If Stefan's N connector has a 50-ohm resistor in it, it's a 10base5 terminator. -- Pete Peter Turnbull Network Manager University of York

AS/400 P03 Questions

by phirkel＠sympatico.ca

Hi folks. I recently acquired an AS/400 P03 "Advanced Portable." This is my first real piece of IBM Midrange hardware, and I have not a clue how to interface with it. I know the OS is a PITA on its own to deal with, but I figure I'll solve one problem at a time. So, I was just wondering, does anybody have any manuals for this sucker (preferably in PDF form!) or know where I can grab them from? There is not a sign of the English manuals for this machine on IBM's website at all. Also, I was wondering if anybody knew how I would go about interfacing with this machine. The DE9 ports on the back of it are definitely not serial ports, and the only other port on it is a SCSI port. Am I missing some cards for this machine? It would almost appear as though the original owner pulled some interface cards for it, but I could be mistaken. Any help would be appreciated! Phil.

Century Data Systems T-50 disks

by pat＠computer-refuge.org

So, I picked up a bunch (5) of Century Data T-50s, (also labelled as "Diva" disk systems), which seem to be multi-platter 54.7MB removable 14" disk-pack drives. Of course, I didn't get any of the disk packs to go with them. My questions are: 1) Does anyone have any available disk packs, or know if they're interchangable with something else that is availble? 2) Does anyone want (some of) them? I don't want to give them up for nothing, but I'm not looking to get too much out of them, and I'd rather give them to someone who finds them useful than let them sit around, especially since I don't have any disk packs (yet). The drives are 150-200lbs each, and are rated at 4A at 208-240V (60Hz IIRC). There's a detailed manual on bitsavers about them: http://computer-refuge.org/bitsavers/centuryData/76205-902_tridentSpec_Nov8… I also have the T2000 disk excerciser and T2001 head alignment boxes for the drives. I have no idea if any of this works; it was probably in storage for 10+ years, and the drives date back to about 1980.

Popular Electronics Magazine

by swtpc6800＠comcast.net

For those of you that answered over 50 on the age question, you probably grew up reading Popular Electronics magazine. (For the U.S. folks anyway.) In the five year period between 1967 and 1971, Southwest Technical Products Corp. (SWTPC) published over 50 articles in Popular Electronics written by Daniel Meyer, Don Lancaster, Louis Garner and others. The idea was to write a construction article then sell the circuit board and kit of parts. Daniel E. Meyer started DEMCO in 1964 and incorporated as SWTPC in 1967. The company lasted until 1986 and had over 100 employees the 1970s. Don Lancaster was not an employee, he just got royalties. Around 1975 SWTPC came out with computer and terminal kits. Don Lancaster was turning out Cookbooks by then (RTL, TTL, CMOS, etc) and started doing musical projects for PAIA. They parted ways. I have been collecting old issues of Popular Electronics and Radio Electronics and scanning a selection of SWTPC projects. This is a history of kits like FM wireless microphones, reverb adapters, musical instruments, audio amps, strobe lights, digital clocks, and digital test equipment. Most of the members of this list have built several of these things over the years. For example, there are some Nixie tube projects in Feb 1970, Dec 1970 and Feb 1971. I have almost finished with Popular Electronics and have posted them to my web site. I will add to the Radio Electronics page next. (Thanks to Jay West for providing the space.) I am scanning the magazines at 300 dpi and storing them as tiff files. I downsize them to 150 dpi JPG files for the web. I have over 1.5 GB of magazine tiff files. I will make them available on a DVD ROM for those who want them. My whole web site will fit on a CD-ROM. I will provide details on how to get these in a few weeks. (I am not looking to make any money on this.) http://www.swtpc.com/mholley/magazines.htm I also have a 1971 SWTPC catalog with a list of which Popular Electronics issue each product came from. http://www.swtpc.com/mholley/Catalog7/Catalog.htm Michael Holley www.swtpc.com/mholley

You're probably thinking of "botch", which means (v) to screw something up, or (n) something which is screwed up. "Kludge" means to make something work, but in an inelegant or clumsy fashion. "Bodge", however, means to adjust or adapt something carefully to fit, perhaps in a way not originally intended; "bodgers" were originally people who did the final fitting of parts to machines and the like. -- Pete Peter Turnbull Network Manager University of York

Michael, I think you are providing a great service. And your web site is an excellent example for all of us trying to save a little history of computers. Thank you. Count me in as one willing to buy any CD or DVD you produce. Do you have the issue that reviewed the PAIA 8700? I don't remember if it was RE or PE. But I do remember buying the computer from the reviewer. Then visiting the designer and finding he had also designed a EPROM burner and monitor to go with it. Don't know if it was ever released. The pace was so fast in those days that single boards machines were outpaced by the many systems. Billy

Yep, it's way older than that.

Vacuum Tubes

by bmachacek＠pcisys.net

Just thought I'd let the listees know that while visiting my local parts and equipment store today (which carries a large amount of discontinued and surplus items of all types), I noticed there was a whole aisle of electronic vacuum tubes there. Guess it's been there for quite a while, I just hadn't noticed it before. I looked at several of the tubes and saw that the addresses listed on the boxes contained no ZIP codes, so I figure that a good part if not all of these tubes are vintage items from back in the '50s or '60s. I have no idea what prices they have on these items as most of the stuff is unmarked, but I know from buying other items there, their prices are usually pretty reasonable. If anyone has any needs of vintage vacuum tubes, contact me off list and I be glad to check on them for you. I saw RCA, GE, and Sylvania there to mention a few and I believe most were for TVs and Radios, but who knows what else I may find there. I'm not an electronics person so I don't know what distinguishes one tube type from another. Let me know if I can be of help to anyone out there. Bill bmachacek at pcisys.net

Yes, I can do it all via the front panel, but I'd like to find a copy of wncedit or something - as I understand it that software will start the punch, read in the binary and store it in a file, then burp the file back out to the device at a later time to recreate the tape. If anyone has such software I'd appreciate contact off-list. Otherwise, I'm gonna start writing something. Jay West

Universal floppy disk controller

Hi The external boxes that have tape drives would have to have a FDC in them. These tape drives were designed to be paralleled with the wires to a floppy.

Universal floppy disk controller

by Watzman＠neo.rr.com

Ok, so we've been discussing various ideas for a universal floppy disk controller. I bought (E-Bay) a used Microsolutions "Backpack" external parallel port floppy disk drive, it's a 3.5" 1.44MB drive. Internally, it is a standard drive (with a 34-pin standard interface) and a floppy to parallel port interface card. The question is -- and it's really a software question -- If I connect a 5.25" drive to the interface (using the standard 34-pin interface) will the device (or, perhaps more to the point, will it's drivers) work? I believe that they actually made a 5.25" model (with a 1.2 meg drive), but I have not been able to find one. The Format program that comes in the software packet has documentation suggesting that it can format a 1.2 meg and even a 360k drive, and I'm guessing that the interface card is the same for the 5.25" and 3.5" models. This might be the answer to being able to access 5.25" drives on a "modern" PC. It would be really cool if 22Disk would work with a drive connected to this thing. I plan to do some testing in the next week or so. It still doesn't solve the eight-inch problem, however. [I know, there's a chance that the controller could be made to work with 8" drives using a funky cable -- but first things first, 5.25" drives.]

using a DRV11 to run an IDE drive?

by GOOI＠oce.nl

Yes, it is possible to connect a DRV11 to an IDE disk drive. However, you must compromise. I connected a IDE disk drive to some simple parallel ports of the I/O Board. But it is PIO mode only, no DMA, so not really fast but it works. The lowest level software is fairly easy. Check www.pdp-11.nl and click on the link "Home-brew PDP-8". You can download the 6809 source code which even resembles (a little) PDP-11 mnemonics. I thought to get it working with 8 bits, but it is a lot easier if you have a 16-bit data path. That means 16 inport bits and 16 outport bits. Further you need a few (6?) extra output lines for control. So perhaps one DRV11 is just not sufficient, but I would say: yes, you can connect an IDE drive to one (or two) DRV11's. BTW, if an IDE hard disk works, I found out that a Compact Flash Card with IDE adapter works just fine too. Solid state disk on your PDP-11! - Henk, PA8PDP. -----Original Message----- From: cctalk-bounces at classiccmp.org To: General Discussion: On-Topic and Off-Topic Posts Sent: 30-3-2005 20:18 Subject: using a DRV11 to run an IDE drive? I've seen an old PC trick that uses the printer port and custom cable to bit-bash interface an IDE hard drive or cdrom using a dos .sys driver. Anyone think it's possible to do the same with a DRV-11 for the pdp11? Features: built in BAR/WCR/CSR circuits, 16 bits in, 16 out. 6 function bits, Attention/Ready/Cycle Request/Bust handshake bits etc Perhaps a small pld or fpga could use the spare handshake or function bits to latch the 3 address bits for the IDE and generate the chip select/read-write etc while the 16 bit input and output busses could be joined via tri-state buffers... I'ts not a replacement for a scsi controller, but it beats hunting down the hard to find bus interface chips and provides a proven already working basic interface. I've got a dozen of the QBUS (and a few UNIBUS) DRx11 boards if someone is interested in fooling with the idea. As a side note - I recall UW's CCNG CE dept fashioned an early MP cluster called using DRV11s to connect LSI11-2s in the 80's. regards -h

Sun 4/330 with faulty serial interface...

by julesrichardsonuk＠yahoo.co.uk

We've got a Sun 4/330 which has bit 6 stuck high in every character output on the console. I don't suppose anyone has schematics for these boards or know how the serial hardware works, do they? The machine looks to be booting OK, so it appears address & data buses are fine - but at the point where characters must be loaded into a parallel register and converted to serial for output it's falling over... I suspect the machine's hard-wired to use only serial port A as console, but either way I couldn't get hold of the right cable to see if the other three serial ports are OK (the latter three being 9-pin male, whilst port A is 25 pin male) I can't think of any line settings, faulty voltage rails etc. that'd cause bit 6 to be stuck high, so I'm assuming it's a hardware fault... cheers Jules

As others have mentioned, the origin much older. There was a long thread on this someplace, maybe in Datamation, about the origin. It was certainly in use before WWII by maintainers of the punched card devices. It showed up in writing in a few articles during the '50's. > The first kludge article triggered five others ("How to maintain a > kludge", etc) in subsequent issues of _DATAMATION_.

I loved those articles. Read all of them when they came out. I still have two of them that I tore out of Datamation. Scans of them would be perfect for the readers of this list. I especially remember "How To Maintain A Kludge" subtitled "Craftily!" Paraphrasing, they had a hall of fame maintenance engineer who talked a customer into using a Kludge Komputer for 6 months even though it had a broken power on switch. Billy

RTP IO controllers (Computer Products, Fort Lauderdale)

by hofmanwb＠worldonline.nl

RTP makes very reliable IO equipment for use in plants and laboratories. The Universal controller can be connected to a wide variety of computers using a module that plugs into the bus of the computer. One can also use an ethernet module or a module with a serial line (DIOC) I did a number of projects where I used DIOCs to couple it with PDP-11 computers, a Foxboro SMS computer and a GE Mark V. The great advantage being that when you change the type of computer you use, the plant wiring can be left unchanged. The great reliability of the RTP stuff ment that even when the computer is worn out, you can leave the RTP in place. Factory experience was that maintenance people completely forgot the RTP gear because it practically never stopped working and bewilderment set in when it once in a while failed. Very convenient is also that after 10 or more years it was perfectly possible to get spare parts. RTP is not for planned obsolescence I would not be surprised at all if spare parts still could be obtained for your stuff.

Am I using > the wrong image for an RQDX3 - maybe ZRQCH0.BIN wants an RQDX2? No, ZRQC is specifically for an RQDX3, and H0 is the proper version for an RD54. It wouldn't work with an RQDX2 (you need ZRQBCx for that). Have you got the correct ROMs in the RQDX3? Correct jumper settings (standard address set on W1-W11, W12-W17 not fitted, W23 should have jumpers between 1-2 and 3-4 for most firmware versions)? Which connectors do you have the drive connected to (should be J1 and J5)? Do you have the terminator resistor pack on the drive itself? "Fatal Controller Error" sounds like the controller isn't doing what the diagnostic expects. Does the RQDX3 pass the self-test? It has a small LED on it; that should go out about 3 seconds after power-up if it passes the selftest. If it doesn't, disconnect the drive and try the power-up selftest again. I've never run ZRQC (or indeed most XXDPv2 diagnostics) the way you're doing it. Are you sure that works? -- Pete Peter Turnbull Network Manager University of York

With an M9058 it shouldn't matter; the drive selects are all tied together on each of J1, J2, J3, J4, each of which is fed by a separate drive select from J12 (the 50-way connection to the RQDX3). For example, J1-26 is fed from J12-30, which is DrvSel.3. Except that there's a removable link for each connector, between DS0 (pin 26) and DS1/2/3 (pins 28/30/32 - DS1/2/3 are hardwired together); make sure that link hasn't been removed. -- Pete Peter Turnbull Network Manager University of York

Obscure DOS question

by websupport＠degnanco.com

Have you tried using the append command? You can put ~512 files in the root and then the rest in directories, but the OS will treat all files within the append "path" as being from the same place. By using the append command, you can tell the OS to look in the other directories without having to declare the directories in your code. It sounds like each file name is unique so it should work (?) append a:;a:\1;a:\2 -Bill > >MS-DOS 3.3 has a limit of 512 entries in the root directory.
