I assume you're not in the USA? So when you buy the average LCD TV in Europe, does it not include the same threaded "F" connector for an RF input, that would be able to tune this "channel 3" (61.25 MHz)? - John

Can anyone id this Wang system? Looks like maybe a box on a desk with another box in the desk with maybe an 8" floppy? http://seattle.craigslist.org/est/sys/2746923849.html Also, a Tek 4051 system and accessories asking $550. (No connection to this listing other than it being local to me.)

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

TV -> D-Sub converter possible?

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/)

TV -> D-Sub converter possible?

by alhartman＠yahoo.com

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. You are probably going to find it easier and cheaper to get an old Color TV on Freecycle to use with the Coco than to adapt it to RGB or DVI. Al > From: "Vintage Coder" <vintagecoder at aol.com> > > I have an old COCO II somewhere but I don't have a television.

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

DT2768-I Diagnostic Program and Manual

by jhfinedp3k＠compsys.to

I need a copy of the diagnostic program for a Qbus Data Translation board: DT2768-I The program that I need runs under RT-11. 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. I checked bitsavers on both the bit and pdf sections, but there was nothing there. Jerome Fine

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

Anything DEC is too scarce to lose in a world dominated by PeeCees! I had hoped for e.g. a Radiator VAX (BA23 ?VAX) to complement my VSII/GPX and perhaps some tower style Alpha hardware.

Oscilloscope vector display driver...

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

Any documentation / schematics for STEbus interfaces

by rwhyre+cctalk＠picrad.com

This 1980s-era bus supported multiple CPUs, and 20 bits of address space. It was also known as IEEE-1000 (until that standard was withdrawn), and used the DIN 41612 connector common to VMEbus systems of that time. I'm trying to find details on interface circuits, schematics for old boards, etc.
