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

Word Perfect 5.1 Documents?

I can work with DCF and Bookmaster _source_ documents, not compiled binary Bookmanager, unfortunately. > I certainly am, since I have and have access to a bunch of > Bookmanager doc that is worthless on PCs although I love it on > mainframes. 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>

Word Perfect 5.1 Documents?

by brian＠quarterbyte.com

I make the bulk of my living converting documents in WordPerfect 5 and up, IBM DCF and Bookmaster, and Interleaf to current formats. Is anyone interested in hearing a bit about the problems using current word processors to import the old formats? It's sort of on-topic, as these are vintage products, even if still in use, but I won't bother the list if it's not of interest.

Velleman PCS64i O-scope Software?

by mbbrutman-cctalk＠brutman.com

I'm going to plunge into the world of slightly more advanced electronics, and one of my teaching tools is a Velleman PCS64i that I just inherited. It's an o-scope front end that interfaces to a PC to provide the display. I'm looking for the DOS software - it is not available on Velleman's web site any more. I found the Windows software, but I'd rather keep it simple for now. If you have the DOS software please let me know .. Thanks, Mike

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

by legalize＠xmission.com

I finally found a tutorial and software to combine smaller scans of large documents into a single mosaic of the larger sheet. <http://hugin.sourceforge.net/tutorials/scans/en.shtml> gives a nice tutorial of how to run hugin panorama tools to generate the mosaic. You must change some parameters from the default and this tutorial explains which of the many parameters you must change. Here are some results I got from using this technique: <http://user.xmission.com/~legalize/tmp/calcomp-schematic.png> <http://user.xmission.com/~legalize/tmp/aesthedes-keyboard.png> -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
