Unix handles file extensions "very poorly"?

by brian＠quarterbyte.com

For the "very poorly" category, I'd like to nominate the DOS & Windows command line globbing semantics, where ? matches one character OR NOTHING. Likewise, ?? matches zero, one or two characters. And ??? matches zero, one, two or three characters. So, del *.? will not delete just "file.a", it will delete "file" as well. This sort of sets the gold standard for poor behavior. Even Microsoft is at odds with itself about what ? means. In the Windows world, the command shell doesn't expand wildcards. Applications have to do it for themselves. The Visual Studio C runtime library globbing routine incorrectly states that '?' matches "exactly one char". So even some of their own developers aren't aware of this. Brian

The National Museum of Computing enjoys tablet resurrection of BBC Domesday Proj

by COURYHOUSE＠aol.com

The National Museum of Computing enjoys tablet resurrection of BBC Domesday Project | Culture24 In 1986, to mark the 900th anniversary of the Domesday Book, the BBC launched the Domesday Project, a then-pioneering campaign where the public could submit pictures and insights on their local area which were then etched onto immortal laserdiscs. High costs and technological advances meant the project was never fully realised in spite of its futuristic ambitions, but last April BBC Learning resurrected the project by making the archives accessible online. _http://bit.ly/tA7ueH_ (http://bit.ly/tA7ueH) Thanks, Ed Sharpe, Archivist for SMECC See the Museum's Web Site at _www.smecc.org_ (http://www.smecc.org/)

Somewhere I have the schematic to tap the input of the RF modulator to drive a Composite Monitor. Several of my Cocos have these. But, newer flat screen TVs may not be able to accept this signal.

OT (Sort of): Programming algorithm for PALCE devices

by cclist＠sydex.com

Pardon if you've heard this before, but... I'm looking for the programming algorithm for Lattice/AMD/Cypress old PALCE devices. I've got a bucketload of them (mostly PLCC) and I'd like to do something with them or trash them, if no luck in the programming department. I've found algorithms for the PEEL devices as well as NS type plain GALs, but nothing on the PALCEs. I know that programming info is usually supplied to OEMs under a NDA, but the technology has passed through a sufficient number of hands that it's hard to believe that nobody has any information. Note, unless it's very cheap (i.e. it costs less than thowing the PALCEs out) I'm not interested in another programmer, but I'm not opposed to tinkering a bit. Thanks for whatever help, --Chuck

If there are other versions, it may be possible to use a different operating system, so please let me know if you have a non-RT-11 version. I believe it is an Analog to Digital Adapter, but I am not sure. However, the module number is definitely DT2768-I. Can anyone help or suggest where it can be found.

Word Perfect 5.1 Documents?

by alhartman＠yahoo.com

Word 5.1 for the Mac runs fine under Executor (http://www.ardi.com). In fact, Executor came about as a way to run Word and Excel on NeXT systems, and was ported to Windows, DOS, and Linux. Executor was how I ran Word for Mac on my PC until Word for Windows eventually caught up. I also used the MagicSac on my Atari-ST with an Epson MX-80 and EPStart (to print with) to use Word on my ST. Later I got a program whose name I forget (Printworks for the Mac - Laser Version?) that was a driver for popular Laser and Dot Matrix Printers that came with a special Apple Serial to Parallel printer cable. I have a Spectre-128 GCR now (I also have ARDI's Transporter One to read Mac GCR disks), but haven't booted my ST in ages. It has a 2.5gb RAM upgrade by AERCO that has stopped working, and I lost the documentation for it, so I can't figure out the jumper settings. Someday, I hope to find them or find someone who has it... Or even more unlikely, run into one of the principles of AERCO. I remember that WordPerfect for the Mac 3.5 ran fine under Classic on MacOS X. Here's a webpage about it:?http://www.columbia.edu/~em36/wpdos/macintosh.html Hope some of this is helpful... Al

Well, if you want "vintage" (and I assume you do) there was at least one such project in an old issue of Byte or Kilobaud (IIRC). Given that typical period (I'm assuming vintage all the way) o- scope's linearity is none too wonderful, you might get away with a single 8255 PPI (or similar parallel chip) and a simple R-2R "ladder" DAC. You can't get much cheaper than that. --Chuck

semi-ot: FPGA memory arbitration methods

by keithvz＠verizon.net

I'm designing a video scan converter to connect my classic Amiga to a new LCD. For the journey, not the destination. Don't want to buy one off the shelf, etc. I need to both read and write to my single-port freeware altera memory controller simultaneously(ok, not exactly at the same time) . I'm converting from 320x200 to 640x400, doing simple pixel doubling. 12-bit color, 4-bits per color, padded to 16-bit for ease of handling within the FPGA. Write side into the memory from amiga->my converter: 1 byte every 70ns. Read side to go from memory->LCD: 1 byte every 20ns. Memory is 8mb, 133mhz access, 16 bits wide, wishbone memory controller has fixed burst size of 2. What are some common ways of doing arbitration? Time slots with buffering between writes? How would this be implemented? Two-port memory controller (I can't find a free, working, easy to use Altera one) Some type of synchronization method? Semaphore/Mutex concepts? My existing setup detects horizontal sync pulse, and reads the entire line from DRAM -> block ram. Since I'm pixel doubling, I only need to read one input line for every two output lines, so I can potentially relax my READ times accordingly. Any advice or recommended references would be appreciated. My efforts are being blogged at http://techtravels.org/?page_id=463 Thanks Keith

You first need to decide how you're going to produce the vectors It's obviously importnat that not only do the 2 DAC output voltages get to the right values (that is, the vector ends i nthe right place), but also that they get there along a 'straight line' from where they were. There are 2 basic ways of doing this, the older one (which has a lower transistor count, but is a right pain to get working) is to do it in the analogue circuirty, that is the DACs 'jump' to the new valuse, the analogue circuitry then genreates the appropariate ramnps to mvoe the beam), the other is to do it digitally, calcualting stairsteps along the vector, moving the DAC ouptus one step at a time, and using analogue circuitry to smooth the result. Unless there are good reasons not to, I would recomend the latter approach. You can porduce the stairsteps eitehr using simple logic ICs (take a look at things like the DEC VT11 system) or using a microprocessor. The latter is probably easier. Jaut about any processor would be fine, I see no reason not to use a Z80 Somethign to be acaefule of is the relative speed of drawing differnt length vectotrs. If the beam moves more slowly on some lines than on otehrs, the former will appaer brighter on the screen.Try to keep drawing speed constant. There are then 2 other parts to the project. The first is the DACs themselves. I think you want more than 8 birs of resulution -- 12 bits would seem to be sensibe (12 bit DACs are not that expensive now). Try to get double-buffered DACs, which allow you to load the input regsters from the processor and then later transfer that registers's contents to the DAC iteself. The advantage of that is the processor can output the 4 values (high and low parts of X and Y) and then update both dacs simultaneously. Without that, you might get little glitches on the display. The otehr part is communication to the host. You have suggested dual-port RAM, which is certianly oen way to do it. I would suggest looking at FIFO buffers (each side cna write to a FIFO which si read by the other side. Of even just a pair of ports with handshake flags. SOemthing like this : '374 ----------- 8 | | 8 Data Bus 1 ---/------| D Q |--------/--------Data Bus 2 | | | Clk OE | ----------- | o WrStb/------+--------+ | | +--+-----------+----RdStb/ | | | | o | | --------- +--|\ | | R | | >o---- Ready Flag | +5V--|D Q|o-----------|/ | | | '00 +-------|> | | | --------- E.g part of '74 The ready flag shoud lbe readable by an input port on each processor. The ideea is the processor 1 can write to the '374 latch, when it does so, it sets the D-type at the bottom, maingign the ready flag line go high. Processor 2 can detect this, it will then read from the '374, clearing the D-type and briinging the ready flag low again. Processor 1 can monitor the flag line too to see when processor 2 has read the data. The NAND means that the ready flag will remain high while proecessor 2 is reading (and thus asserting the reset line to the D-type) so proecessor 1 doesn't try to writ at this thime (when it couldn't set the D-type). Take a look at the hP120 schematics to see how a pair of Z80z can communicate using this sort of circuitry. -tony

Word Perfect 5.1 Documents?

by brian＠quarterbyte.com

I wrote this note yesterday, but replied to cctalk-request by mistake. (The listserv engine wasn't impressed, by the way). ... If you're using the built-in import or export filters provided with Word, WordPerfect, OpenOffice, or whatever, for your own documents, check over the results *very carefully* on a computer that does not have the old word processor installed. For documents anything more complex than a grocery list, the conversion tools provided with document processing programs are not quite what you'd hope for. One bit of advice I have is, if you want to convert old documents, do it now. As each new edition of Word or Corel Office comes out, tools for converting the oldest formats either disappear, or they stop working and the vendors aren't doing the QA to know this. (The current version of Quattro Pro crashes trying to open many spreadsheets in the old .WB2 and .WB3 formats, for instance). People in this group may have intermediate, older software versions lying around, but most folks don't. My experience is that both import and export tools do a decent job of getting raw text in and out. Formatting, styling, graphics, equations, cross references and outline numbering schemes? Not so much. But this is where the investment in a document lies. Text is cheap. One way of converting legacy formats is to have printed pages retyped in China or India at under a dollar a page. (This is a real industry.) But formatting is really expensive. Complex documents with drawings, math or tables can cost a business $25 to 100 a page, or more, to have reworked by skilled clerical or technical staff. Word's import filters are *horrible*. The result *might* look ok at first, but it goes downhill fast one you start editing or try to apply a consistent stylesheet. Their treatment of equations and graphics is downright dangerous. The filter that extracts WordPerfect's WPG graphics only converts the basic [0,x] character set for text that appears in labels in graphics. Characters in the other sets turn into spaces. I saw a drawing that used the "1/2" symbol in a label that read something along the lines of "IMPORTANT: TIGHTEN THIS NUT TO 2 1/2 FOOT POUNDS" come out "IMPORTANT: TIGHTEN THIS NUT TO 2 FOOT POUNDS." The equation importer is no better. "grad" (nabla, the upside-down triangle) and "Delta" both come out as an uppercase Delta. Some other symbols are dropped entirely. Many equations simply don't convert at all. This has been the state of the filters since at least Office 97. Microsoft has made no corrections. OpenOffice? I've found it crashy, especially when trying to export or import. Small documents, OK. Big, complex documents, no. Export tools are typically worse than import tools. Vendors aren't really motivated to provide a good tool that you can use to escape from their product line. You can usually get away with *publishing* to another format, but you usually won't get a maintainable *source* document. (By maintainable, I mean a document with cross-references intact, outline numbering organized the way the new environment's native numbering system works, typography governed by a single consistent style sheet, and so on). My experience with exporting things from WordPerfect is that equations are not editable, or are not converted at all. Graphics exported to any vector format (e.g. WMF) still use the proprietary WordPerfect fonts, so again, symbols beyond basic ASCII are a big problem. Once you move the exported document to a system that doesn't have WordPerfect installed, symbols disappear from the graphics. PDFs with embedded fonts get around this, but, PDFs are really bad format for documents that have to be maintained. (A couple of years ago we lost a bid to do a conversion for a major US oil company. They decided to convert a huge archive of refinery operating manuals in-house on the cheap, by making PDFs and then converting the PDFs to Word. They will be losing all automatic cross references and numbering. After a few future edits, "Before opening this valve, see the critical warnings in step 3.32.4 on page 147" will be pointing to the wrong comments on the wrong page because these numbers are now just literal text. Management didn't seem to be at all concerned about this. If I lived next to a refinery on the Gulf Coast, I'd move.)

Looking for: "STP Connector Card" for a VT103

by derschjo＠mail.msu.edu

This is a long shot -- anyone have a spare "STP Connector Card" for a VT103? This is a small paddle board that plugs into the main VT100 circuit board (on the J3 slot). Basically it re-routes the external serial port internally in order to allow it to connect to the VT-103's internal PDP-11. It's a completely passive device and I have the schematic, PCB layout, and pinouts so it's not looking like it would be too difficult to just build one, but I figured I'd ask before I went through the effort. (And for those interested, I'm finally doing something fun with the VT-103 I got a few years ago. I've upgraded the backplane to 22 bits, and I've installed a QED 993 board (a 3rd-party 11/93 clone with 4mb memory onboard). Now I just need to work out the SLU connections for the terminal itself (hence the STP connector) and work out some storage... maybe I'll just borrow the SCSI card from my MicroVAX...) Thanks as always, Josh

Oscilloscope vector display driver...

by dougcoward＠hotmail.com

Chuck said: > Well, if you want "vintage" (and I assume you do) there was at least > one such project in an old issue of Byte or Kilobaud (IIRC). Wow, that takes me back. I built one back in late 1984 on a board to fit into the expansion port of the C64. I believe it was Byte and I believe the project was originally for the Apple II. AFAIR The board had 16 buffers on the address lines feeding two precision resistor networks. One network for the lower 8 address lines connected to the oscilloscope X input. The other network for the upper 8 address lines fed the Y input. Giving you a 256 x 256 vector display of where the processor was accessing memory. I had a paying job to break software protection on some C64 games. And this help alot to determine which parts of memory where pieces of code were being stored. For a while I toyed with the idea of writing a vector verse of Tic-Tac-Toe by programatically putting jmp code pieces out in memory and jump from piece to piece in a loop create the graphics on the oscilloscope. --Doug Coward Poulsbo, WA The new home of the Analog Museum and History Center is http://www.cowardstereoview.com/analog

rj45 -> wireless ->rjr5 ?

by rdawson16＠hotmail.com

On the off chance somebody here has done this: I have 2 wireless routers, one connects to cable and I have an internet connection. Its a wifi too. I want to pick up that wireless signal with another router, locate it in the other part of the house to connect a wired ethernet device. its as if I want a wireless adapter, but not having an output that is usb, but a ethernet jack. Is this possible? Its to avoid running a long cat 5 cable thru the house. Randy

Oscilloscope vector display driver...

by wh.sudbrink＠verizon.net

Hi All, I'm thinking of building a "somewhat vintage" two-channel DAC board, intended to drive an oscilloscope as a vector display. I'm just considering parts now, unless someone has a really good design already set to build. By "somewhat vintage" what I mean is that I don't want to just drop in a modern "super chip" that will have ten (or more) times the power of the intended host computer which, by the way, is an SWTPc 6800. I figure the board will have some 8-bit processor on it. I'm leaning towards a Z-80. It will have an EPROM, some scratch static RAM, some glue logic to manage the communication with the SS-30 bus... and this is where I get fuzzy... a 1Kx8 dual ported static RAM and two DACs. These last two elements (the dual ported SRAM and the DACs) are where I don't have any experience. A little googling has led me to the IDT7130 for the dual ported SRAM and the DAC0830 for the DACs. Does anybody in cctalk land have experience with either or both of these chips? I have a source for the DAC0830, but I don't have a source for the IDT7130 yet. The basic idea of the design is for the 6800 to write a vertex list into the dual ported SRAM which the Z-80 then reads and pushes to the DACs. I'm hoping I can just hang these chips off of the Z-80 address and data busses like the RAM and EPROM but I need to do some more reading of the spec sheets. Any help greatly appreciated, Bill S.

Unibug ROM for TI TM990/189 University Board

by eric＠brouhaha.com

Does anyone have the "Unibug" ROM that was supplied with the TI TM990/189 University Board? This was an educational and evaluation board for the TMS9980 microprocessor, an 8-bit-bus version of the TMS9900. It's not hard to find images of the "University BASIC" ROMs on the net. Those ROMs replaced the Unibug ROM. Thanks, Eric

The comments I wrote yesterday (and posted to cctalk-request by mistake) are about the import and export filters provided with Word, WordPerfect, OpenOffice etc, not about DCF/Bookmaster, which really live in another world. I'll post those comments shortly. Bookmaster is pretty great, and it converts to DITA XML in a rather straightforward way, which is no surprise since the latter is a direct descendent of the former. 1978: :note text='Warning'. Don't run with scissors. :enote. 2011: <note type='warning'> Don't run with scissors. </note> DCF (which is the IBM branch of the RUNOFF family tree, upon which Bookmaster is based) is another story. In the hands of documentation folks, it was a markup format. In the hands of engineers, it was a programming language. When engineers wrote documentation, it was a hairy mess. I've untangled some "interesting" DCF documents. Brian

tools for reverse engineering schematics from boards?

by legalize＠xmission.com

I've got a bunch of Nuclear Data peripheral circuit boards that I need to reverse engineer. They are simple circuit boards with all the tracings visible (i.e. no internal layers) and the parts are all 7400 series logic in standard DIP packaging. If I were to do this manually, I would take high resolution photographs of both sides of the board. From the photographs, I would try to recreate engineering drawings: part placement and circuit topology. I'm wondering what kind of tools are out there that would assist in this. Could I process the photos to extract the topology of the printed circuit traces? Can I correlate this with image recognition of the part packages and combine them to product a netlist? I'd appreciate hearing any experiences from others that have reverse engineered circuitry. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

wanted: raised flooring for cheap

by vintagecoder＠aol.com

The setups I have seen require a lot of square footage. You have printers, tape drives, and big DASD farms connecting to controllers and communications controllers and finally the mainframe which may itself be a complex consisting of more than one physical box. I have not seen a machine room that wasn't all raised floor. I don't know that a small setup exists with the bus and tag technology but that was years ago. The new stuff is smaller and also doesn't need raised floor. Seems like it's probably an either or situation. When you need raised floor you need a lot. When you don't, you don't. ------Original Message------ From: ben Sender: cctalk-bounces at classiccmp.org To: cctalk at classiccmp.org ReplyTo: General Discussion: On-Topic and Off-Topic Posts Subject: Re: wanted: raised flooring for cheap Sent: 7 Dec 2011 18:26 On 12/7/2011 11:10 AM, Vintage Coder wrote: > Bus and tag cables are huge. The other problem with raised flooring is who's floor are you on? With a small system, could a raised island be built, with the computing equipment raised say a foot or so, with just false floor between the equipment. Ben.

how to: automatically combine images into a larger mosaic

The Strange Birth and Long Life of Unix

by a50mhzham＠gmail.com

Interesting article about the 40th anniversary of the progenitor of many modern operating systems. It even mentions our very own Al Kossow, "One holy grail that eluded us for a long time was the first edition of Unix in any form, electronic or otherwise. Then, in 2006, Al Kossow >from the <http://www.computerhistory.org/>Computer History Museum, in Mountain View, Calif., unearthed a printed study of Unix dated 1972, which not only covered the internal workings of Unix but also included a complete assembly listing of the kernel, the main component of this operating system. This was an amazing find?like discovering an old Ford Model T collecting dust in a corner of a barn. But we didn't just want to admire the chrome work from afar. We wanted to see the thing run again." http://spectrum.ieee.org/computing/software/the-strange-birth-and-long-life… I love the picture of the very first man page. 601 .

Tandata TD1100 printer port

by ard＠p850ug1.demon.co.uk

As I mnentioend the other night, I've added the parallel printer port to that TD1100 viewdata terminal. The output is a DA15 socket, and in fact the hardest part of adding the port was cutting the back panel of the unit ot allow the conenctor to come through. I had to remove the back panel entirely from the PCB, which invovled desoldering the line wires and the mains wiring.... Anyway. I then had to make a cable from the DA15 to a 36 pin Microribbon conenctor to conenct ot a Cnetronics-interfaced printer. As I mentioend, I'd gueessed as to what the signals were, so I sued those guesses for the initial wiring. Connected the unit to an old Epson FX80+ and pressed the 'print' key on the terminal. It printed. Some garbage, some readable text. I then rememebred the pritner setup screen (type 'P#' at the dialer screen) and found it was set to 'teletext compatible' -- i.e. it would handle the various teletxt/viewdata controll codes and graphics. I reset it to 'ASCII text' and tried again. This time it printed correctly -- almsot. It was double-spacign the lines. I then realsied that the pritner had previously been used with a BBC micro, a machine that, by default, sends only a <CR> as a newline. There's a DIP swithc in most old Epsons to cater for this, it foces the AutoFeedXT line on the inteface conenctor low. Only problem was, I didn't haev the printer manaul. Oh well, I just took it apart and traced the conenctions from the AutoFeedXT pin through the filter resistor to a DRIP swithc. Turnrf it off (so it no longer asserted the AutoFeedXT signal) and put the pritner together. This time it worked fine. My gueses on the printer port signals had probed to be correct. In case anyoen else wants to do it, here's the wirelist (and colours) of the cable I made : 1 o----D3------Or----o 5 2 o----D6------Bu----o 8 3 o----D7------Pu----o 9 4 o----D0------Bk----o 2 5 o----D4------Y-----o 6 6 o----D5------Gn----o 7 7 o----Err/----R/Bu--o 32 8 o----Gnd-----Gy----o 19 9 o----Gnd-----W-----o 30 10 o----D1------Be----o 3 11 o----D2------R-----o 4 12 o----Init/---Tq----o 31 13 o----Stb/----Pk----o 1 14 o----Ack/----R/Y---o 10 15 o----Busy----R/Gn--o 11 DA15P 36 pin Microribbon -tony

Wanted -- cheap GPIB / HPIB / IEEE488 cables!

by classiccmp＠philpem.me.uk

Hi guys, Does anyone here have a surplus of GPIB, HPIB or IEEE488 cables (they're all the same thing) with metric threads? (the thumbscrews will probably be black -- the silver ones are AIUI usually some SAE thread type or other). I'm after a couple of the short 1-2ft "instrument to instrument" cables, a 1-metre (to replace a nasty little knockoff cable which has excessively long thumbscrews) and a 2-metre (to replace a buggered up Belden cable). These seem to be commanding utterly insane prices on Greed-Bay, and are basically unavailable elsewhere... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

The old research division is still mostly intact, and their physical library exists. ... The paper documents tauntingly sport IDs announcing that they had been digitized by Big Digitization Corp at some point in the past. Who knows what happened to that archive." --Toby

Archiving ST-506 drives

by legalize＠xmission.com

What's the best way to do this? I believe I have vintage PCs with ISA slots and ST-506 hard drive controllers, so that may be an option. However, the drives I want to archive are not from a PC system, but have the ST-506 electrical interface. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

Tandata (Tantel) Viewdata terminal configuration

by ard＠p850ug1.demon.co.uk

I've got a small Viewdate (PRestel) terminal on the bench at the momnet, a Tandata TD1100. I've made a few modifications, in particular I've removed the RF modualtor (which I find to be a pain), added the RGB oupt ucomponents, and fitted a 3 pin DIN socket in place of the redundant RF output socket with the pins wired to the audio signal, compostie video and ground. So I can now use it with compoite or RGB monitors. I've also added the printer port components. [For reference, the RGB output components are the ones hidden by the modulator can. The IC is a 74LS364, there are 4 resistors, all 220 Ohm, 5 picofuses to protect the telephone line agians a breakdown i nthe monitor wihci puts a high voltage on the input pins, 8 5.6V zener diodes and the 5 pin DIN socket. Fit the link F-D to get TTL sync. For the compopstie output, fit 10uF or 47uF capacitors in the 2 spaces hiddle by the modulator. Reduse the seires reissotr in the compostie signal (I think it's R9 on the PCB) from 1k to 220 Ohms. Fit a DIN socket in place of the RF output socket (the fibreglass insualtor of the latter can be drileld ot take a single-hole mountign DIN socket) and wire the pins to ground, the right hand hole of R5 (audio) and hole E (video). For the pritner prot, the 3 missign chips are 74LS374, a 74LS365 and a 74LS74. Since these have different numebrs of pins, it's obvious which goes where. The outptu conenctor is a DA15, you have yo cut a regtasnlge out of the back panel.] anyway, it does seem to work. I've conencted it to another modem[1] -- neither needs any DC line 'battery' so just connecting them together was enough. I've discovered that from the 'dialer' screen, presing '#' energises the line relay and conencts the lien audio to the audio output. If it then detecs a carrier from the remote modem, it goes into on-line mode, it then disables audio fro mthe line to the audio output and turns on tis transmit carrier. Obviosuly trasmit ias at 75 buard, receive is at 1200 baud, it's 7 bits, even parity (and it cares about the parity). [1] An old Miracle WS2000, the black box with 3 knovbs on the front that weas commonly used with the BBC micor. It's an AM7910 and not much else, I like it because it can be controlled from the front paenl rotary swiches, and I Know exactly waht it's going to do. Since I only use it on a private system (my line simulator), I've eneabled the Bell modes by remove the pin from the rotary switch. I'd love to find the autodial and answer boards for it, but no chance... So far, so good. But one thing I can''t figure out on this TD1100 is the dialer. The dialer scrren shows 6 telehone numbers which I beleive are stored in battery-backed RAM inside the unit. at this screen, typing in 1 to 6 followed by a '#' dials that number foem the list and then goes itn othe on-line mode. As I said, a plain '# gopes into that mode iwthout dialing. Most other keys give a 'Please Try Again' error message. A 'P' (must be upper case, and note that caps lock is cleaered whenever you get to this screen) goes ota printer setup page (3 options). What I can't do is figure out hoe to set the numbers and/or dial an arbitrary number entered from the keyboard (ad since the battery in my unit is long dead and I've removed it, all the numbers on the lsit are strigns of zeros, not that useful!). I really don't want ot have to disassemble the firmware. Another thing that would be useful, but I probably can figure this out, is the ppinout of the DA15 pritnr conenctor. It's clearly TTL level parallel. There are 2 opuptu ports, oen 8 bits (data I assume), one 2 bits (I guess one of thsoe is strobe, what the other is I don't know) and 3 inputs (one is conencted to a pusle-stretcher, adn is prsumably Ack/, one of the others is probably Busy). Any ideas? -tony

manx mirror archive restored

by legalize＠xmission.com

There were a bunch of documents that used to be mirrored on vt100.net. Someone sent me a tarball with a partial backup and I found another place on the net that had a backup copy of the mirrored documents. I've transferred them over to manx.classiccmp.org and you can browse them here: <http://manx.classiccmp.org/mirror/> I've also grabbed some stuff from vt100.net in case that content disappears again. At some point the manx database will have its URLs updated, but that is a lower priority item at the moment. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

Official DEC card mechanical specs

by fraveydank＠gmail.com

I've been more seriously contemplating my QBUS multi-purpose card idea now that one of my other major projects is nearly done. I've been unable to find any official or even quasi-official mechanical specs for DEC cards (QBUS, UNIBUS, etc). I'm obviously looking in the wrong places, since there's a wide degree of uniformity; I'm looking for things like board outlines, edge bevels, component clearances and the like. The electrical specs are in quite a few places, so I'm not worried about that. Interestingly enough, my Douglas CAD software for my old Mac has DEC card outline templates pre-stored. However, I'm not even entirely sure Douglas makes PCBs anymore, and I imagine they can't beat my preferred board house on price (I'd love to be wrong). - Dave

Need A Wyse WY-50?

by ohh＠panix.com

There's a Wyse WY-50 terminal which has been sitting in a box in a warehouse for nobody-really-knows-how-long which has recently come into my hands. I haven't tried powering it up - it probably wants a good checking-out first - but it looks to be in very good cosmetic condition, and the people who gave it to me say it was working when it was stowed. Keyboard, power cord and manual are all with it. It's in Seattle. Free if you can pick it up (Seattle Center, Opera House, we can arrange a time), or UPS shipping costs if you want it shipped. Slight preference to anyone who's willing to pick it up. :) E-mail ohh at panix.com if interested. -O.-

VT100, PDT 11/150

by jgessling＠yahoo.com

Looking through some pictures my sister in law had brought over.? Everyone was ooing and ahhing about the cute kids, except me.? I noticed in the background of one my old DEC PDT 11/150 and a VT100.? Circa 1982 those were the latest and with a modem allowed me to log in to the VAX at work.? Good stuff!? Also a Heathkit H19 terminal that I had built from a kit. The PDT 11/150 was an LSI-11 single board computer stacked on top of 2 8in floppies.? That thing really clattered when I ran it.? I had bought a UCSD P-system for it from a UCSD spin off that supported that box.? The PASCAL was compatible with the Apple II so it was actually useful.? I wrote a 2D gravity modeling program for it that my boss ran on his Apple II to his hearts content without any mainframe charges.?? I can even remember how much it all cost.? The PASCAL system was $500, the H19 $500.? The VT100 and modem were loaners from work, the PDT 11 was free, DEC was giving them away to good customers, I suppose because they couldn't sell them.? Good times. Regards, Jim

I have a similar pile of old Mac Think C era books and Mac developer program newsletters. And then there's all the MSDN CDs and C compiler stuffs from various PC compilers.

SCSI replacements (was Re: Data General computer)

What >happened there? > >JIm > > > >-------------------------------------------------------------------------------- > Hi Jim! Thanks! Although the SCSI to IDE/SD project is going slowly I did get about 20 PCBs earlier this year. So far we've gotten some builds underway and at least one builder has gotten the board to run Zapple as a debug monitor as a "proof of life". The project is quite a ways and is nearly complete. All it needs is some community involvement to push it to completion. In particular, it needs verification of the IDE, SD, and SCSI interfaces. Then it will need some firmware to handle the conversion. The main advantage of the project is that it is completely open and free. If there is sufficient interest, I will order another batch of PCBs or try to get those builders with incomplete PCBs to swap them out. In my opinion, this project is nearly complete and the shortest path to a working SCSI to IDE/SD converter. All it needs is some TLC and push from the community. As per the usual N8VEM guidelines this board uses all commonly available parts and is designed to be simple to assemble using basic tools. Please help finish this project. I sincerely think it will be valuable for years to come and it would be nice to discuss an actual converter during this frequent topic on CCTALK. Thanks and have a nice day!

russian PDP-11 like K1801BM2 CPU Startup reading w/o address?

by holm＠freibergnet.de

I want to play with a russian K1801BM2 CPU (K1801VM2). My russian from the school is very very rusty and so I have problems to understand what's going on with this CPU while startup. There is some "besadresnoe tschtanie", a read from the bus w/o sending out an address before w/o active SYNC. It is right, that this read is building the upper 8 bits from the start address in the rom area with Systemu Mode (Halt Mode) = 1? Can anyone please confirm this? BTW: how is this external register to be done in HW? Does anyone know if there are schematics of SBCs existing w/o special support ICs like The K1801VP1-55 or so?

SCSI hard drives of large form factors

by michael.99.thompson＠gmail.com

>Here's something I was thinking about the other day. I *know* for a fact that SCSI interface hard drives existed with 8" platters. I've never seen one, however. Does anyone know of any specific model numbers, or have any product information or pictures of such devices? I just looked in my collection of 8" drives. I have two 8" Imprimis/CDC 97201-12G PA8P1A ST81236N Sabre drives with the original style SCSI connectors on the back. There are manuals for the drive on Bitsavers at: http://www.bitsavers.org/pdf/cdc/discs/sabre/83325700N_PA8xx_736-1230mb_Par…, and http://www.bitsavers.org/pdf/cdc/discs/sabre/83325720F_PA8xx_736-1230mb_Mai….

Looking for Vaxstation 3100 model 30 RAM expansion

I know I kind of touched on this in my earlier diagnostic query, but I thought I'd send out a more obvious request: Anyone have a memory expansion for a Vaxstation 3100 (model 30) they're willing to part with? Something 8MB or larger would be wonderful. I have a wide variety of DEC (and other) hardware to trade. Thanks as always, Josh

Storing cables

by ard＠p850ug1.demon.co.uk

I suspect many of use have this sort of problem, and I'd be interested in hearing any solutions to it. Moat classic computers have various little bits that go with them, in particular cables and connector adaptors. In some cases these are specific to one particular type of machine (e.g. the user prot adaptor for the Acor Cabridge Workstation), others are rather more generic (the same cassette lead fits all TRS-80 M1, M3, M4 and M100 machins, along with the IBM 5150), and still others are totally generic (HPIB cables, 'kettle leads', etc). I find storing thes parts, partircularly the 'somewhat generic' ones is a problem, and I can never find what I need. You cna't categorise them by machine (becase, for example, a TRS-80 M1 RS232 cable is specific to that machine (it plugs into an esdge conenctor on the EI), the pritner cable also fits the M3 and M4 machines, the cassette lead also fits the IBM PC), you vcan;'t realy do it by function (a DBd25-DB25 lead could be used for several purposes, not only RS232), and so on. Any ideas? I am getting fed up with having to re-make a cable which I know I made a couple years earlier, but for a different machine, and which I now can't find. -tony

Archiving Xebec S1410 / S1410A controlled ST-506 drives

by glen.slick＠gmail.com

As a follow up to Richard's question, does anyone have any experience archiving an Xebec S1410 / S1410A SASI controlled drive from a relatively modern system? If the SASI controller doesn't support the standard SCSI Inquiry and Read Capacity commands I wouldn't expect that you could simply connect it to a SCSI host controller on a Linux box and "dd" the drive contents to a disk image file. -Glen

I have no direct connection to this sale, just passing it on. He is local to me in Orange County, Ca. Jim 320803364119

Need: Intel "ISIS-II" development stuff for PC (DOS)

by hachti＠hachti.de

Hello everybody, I came across some MCS-48 SW project which I have to get into active maintenance again. I have assembly source and listings. And some DOS batch files wich run commands like C:\ISIS\ASM80\HEXOBJ. And there are strange .CSD files which seem to contain some kind of build rules similar to a makefile. In the listings there's mentioned an ISIS-II ASM48 assembler. And an ISIS-II linker as well. I *have* to get that stuff up and working again. What I assume: - ISIS-II is an Intel Intellec's OS. - The Tools from ISIS-II have been ported to MS-DOS but still call themselves "ISIS-II" in the listings they produce. Am I right? Does anybody have the software? Heeeelp, I'm lost! It would be very nice if one of this list could help me out. Any input welcome! Kind regards, Philipp

Interpreting Vaxstation 3100 memory error

by derschjo＠mail.msu.edu

Hi all -- Picked up a Vaxstation 3100 today at the SRCS meeting. There is some minor corrosion on the memory and motherboard PCBs, some due to prolonged exposure to moisture, and some due to a leaking clock battery. I've cleaned up the corrosion and it doesn't appear to have done any serious damage. At POST it identifies itself as a KA42-A, which I believe makes it a Model 30. I'm getting error messages from the POST and I'm unsure how to interpret them -- the manuals have not been 100% clear. Here's what I get: KA42-A V1.3 F...E...D...C...B...A...9...8...7...6...5...4...3_..2_..1?.. ? E 0040 0000.0005 ? C 0080 0000.4001 ? B 0010 000C.0081 ?? 1 00C0 0011.700E The (E) error I expect since there's no clock battery. The (C) is also expected since I don't have a keyboard/mouse plugged in (just using the serial console). Similarly, (1) is also expected since I don't currently have the ethernet interface hooked up to anything. (B) is what's confusing me -- my understanding is that a single question mark indicates a "soft" error, described in the manual thus: "Usually, a question mark (?) in the power-up summary indicates a soft error and the system may be usable without replacing any FRUs." OK. What does that mean for memory, and how do I interpret the error code? I know that the "000C" part indicates the amount of memory installed -- what does "0081" mean in this context, and should I be concerned? For further reference, "test 50" gives the following for memory: ? MEM 000C.0081 00400000 The machine does boot (VMS 6.0 off of two very noisy 104MB drives) and it seems to work OK, though I haven't stressed it much yet. Any suggestions here would be much appreciated. Thanks! Josh

gopher mirror of the IF-Archive

by dgriffi＠cs.csubak.edu

I was wondering if any of you who are running gopher servers might be interested in hosting a mirror of the Interactive Fiction Archive. See http://www.if-archive.org/. I got back into the Frotz codebase and this thought popped up. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

VHDL PDP11

by sytsezelf＠gmail.com

Today, 11-11-11, seems like a nice day to announce the availability of yet another PDP-11 implementation in VHDL. I have created a website for my project, PDP2011 ? a re-creation of the well known series of PDP-11 computer systems in VHDL. After nearly four years of work, the project is almost finished; you can run a complete Unibus PDP-11 system with console, disks and other peripherals on a simple low cost FPGA development board. Original operating system software, like V5-V7 versions of Unix and BSD 2.11 work. I would like to invite you to come to http://pdp2011.sytse.net/<http://www.google.com/url?sa=D&q=http://pdp2011.sytse.net/&usg=AFQjCNHsCke6…> Regards Sytse

RSTS > V9.6??

by tshoppa＠wmata.com

Ignore the half-baked stuff. Fully baked seems to still be in progress. (I think Buck Henry was responsible for that line in The Graduate). Progress is very slow and what progress there is, isn't really due to any of my efforts (don't have nearly enough time to play with -11's anymore) but to others. Apache here is doing weird-ass stuff and serving up random alphabetical URL's as stuff that just happens to be in various public_html directories on my servers (apparently sometimes from other virtual domains...???) but which was never intended to be public in that sense. My fault for not understanding what Apache is doing.

RSTS > V9.6??

by oe5ewl＠gmail.com

Good evening to all DEC-Enthusiasts, stumbling around the internet and my own archive I wondered about the RSTS/E Distributions later than 9.6. I'd like to play with one of the last versions but nothing seems to be available. Somewhere I had read about licensing issues and the Mentec Discussion here. Does anyone know more of the current RSTS/E Licensing status? Or even has a distribution/documentation scanned? Any help with this questions would be greatly appreciated!

Rhino Mark III Robot Arm Controller Schematic

by wheagy＠gmail.com

Hi, Does anyone have a schematic for the Rhino Mark III Controller? I acquired a Rhino robot arm and the B motor encoder channel seems to not be working properly and I'd like to try to isolate which parts of the controller board are unique to the B channel. Alternatively, if there are any Rhino experts that could help point me in the right direction, that would also be appreciated. I think I've isolated it to a problem with the controller and not the motor/encoder or the teach pendant. Using a scope, the output from the B channel is very different than the other 7 channels. Thanks...Win

Assuming this is an MMJ socket, you just need to loop DSR to DTR (ie the two outer pins), RXD to TXD and the two grounds in the middle to each other. If any of the memory is on an expansion board, try removing it and repeating the test to see if the problem is on the system board. (I've had some battery corrosion problems in a VS3100. It doesn't look too severe but test B seems to fail in the middle and go back to the start, repeating over and over. I must get around to making a better attempt to clean it and check the traces.)
