Thanks for the warning. We had considered licensing this for some operations here, but stayed with command line ftp. Glad we did, now.

Looking for plot data files

by Robert_Feldman＠jdedwards.com

Technically ;) Autodesk sells the user only one license, which gets transfered to the new software version as it is upgraded. Therefore, the only way you could get a copy that would be even marginally legal would be if the user stopped using AutoCAD or purchased a complete new copy to replace the old one. I haven't had to do a regular upgrade since about Release 10 (where I work now is at an AutoCAD Registered Developer, so we have different licensing terms), but at that time, you had to return the original of the serialized first program disk in order to get the upgrade.

My MS-DOS 5.0 manual says that with the /U, FORMAT "Destroys all existing data on a disk", whatever that means. I think you are entirely correct. But AFIK the /U and /Q only apply to formatting floppy disks. However I could be wrong about that. Joe

Shugart 801 floppy drives

by dwightk.elvey＠amd.com

Hi Jules The most common problems of these machines are: 1. small bits of the belt rubber stuck to the pullies. 2. dirty or magnitized head 3. sticking bearings or screw in head assembly. I clean the surfaces of the pullies by dragging a knife along the surface while spinning. This is the most over looked cause.

MOS Technology 6502 manuals

by philpem＠dsl.pipex.com

Hi all, I've just grabbed a copy of the MOS Technology "MOS Microcomputers Hardware Manual", dated January 1976, MOS publication number 6500-10A from http://www.spies.com/~aek/pdf/ . I've already got a (poor quality) reprint of the August 1975 version (publication number 6500-10). Does anyone know what - if anything - was changed in the January 1976 revision of the manual? Is it worth my while printing the newer manual out again and having it spiral-bound? I was going to print out the MOS Programmer's Manual (doc #6500-50A) anyway. Alternatively, does anyone have original copies of these manuals or the Synertek or Rockwell equivalents? An original MOS Hardware Manual and Programmer's Manual would be nice to have around, but I can live with a laser-print or photocopy if need be. Thanks. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)dsl.pipex.com | ViewFinder, Ethernet (Acorn AEH62), http://www.philpem.dsl.pipex.com/ | 8xCD, framegrabber, Teletext ...

Looking for plot data files

by Robert_Feldman＠jdedwards.com

You can get a DXF-to-HPGL converter (such as http://www.imagespro.com/programs/2287/ ), then send the HPGL to the plotter. As far as getting an old copy of AutoCAD, you can pretty much forget that. AutoDesk has been very aggressive at maintaing their IP. The only version I have found on the web is one customized for the DEC Rainbow. There were some other 2D CAD packages such as TurboCAD that could read DXF, and were available as trial or free versions. You could Google for an older version that is compatable with your plotters.

Thanks for the pointer. Searching for DXF on the web throws up a bunch of possible stuff. Now to figure out how to plot DXF files cheaply! I think the shuttel picture goes back further than that. Tektronix used it extensivly in their promotions of the 40xx series, that would be late 70's -- hbp

Vintage Computer Marketplace Grand Opening!

by vcf＠siconic.com

The Vintage Computer Festival is proud to announce the grand opening of the Vintage Computer Marketplace, THE place on the web to buy, sell and trade vintage computers! http://marketplace.vintage.org The Vintage Computer Marketplace (VCM) has been designed to cater specifically to the vintage computer collector. The site features innovative sale and auction tools as well as inventory tools that allow you to keep a database of your computer collection online. It also features a powerful search tool to guarantee you find exactly what you're looking for. No more searches that return dozens or even hundreds of irrelevant hits. At the VCM, you can Buy and Sell using standard fixed price and auction mechanisms. But we also feature innovative sale and auction mechanisms you won't find anywhere else, plus the ability to trade or even put items in your collection up for temporary loan. Our powerful inventory feature allows you to maintain a database of your entire collection, including hardware, software, documentation, books, magazines, even ephemera such as posters, buttons, t-shirts, etc., in one centralized location. Our input forms are intuitive and easy to use. Once your collection is entered into the database, selling or trading off items to other collectors is a breeze. Even the database record gets transfered, so no additional data entry will be required, and a line of provenance is automatically created. The VCM really takes computer collecting to the next level! The VCM offers one of the most powerful search engines on the web. Instead of putting in your search terms and then sifting through perhaps dozens or even hundreds of irrelevant links, you can target your search to exactly the make and model of the item you are looking for. We've pre-programmed hundreds of computer manufactures and thousands of models into our database, and are constantly updating it with new information. When you do a search on the VCM, you'll always find what you're looking for immediately. During our grand opening period, the VCM will be free to use for an initial period of 6 weeks. After that time, the service will still be free to use for most users. Visit the VCM website and click on the "Help" link for more information. The Vintage Computer Marketplace awaits your visit. Sign up now. It's FREE! http://marketplace.vintage.org This is a live beta roll-out of the Vintage Computer Marketplace. As such, you have the option of being actively involved in the final stages of testing and development. Simply check the box in the user registration form indicating you'd like to be enrolled in the VCM Beta Tester mailing list and you'll be able to follow all the behind-the- scenes development and also make suggestions on what features you'd like to see. This is YOUR site. We want your feedback! We look forward to seeing you on the Vintage Computer Marketplace!

Low Level Format

by Robert_Feldman＠jdedwards.com

I thought /U was "unconditional", meaning that you cannot later reverse the formatting and recover the previous data. Without /U, FORMAT would save a hidden copy of the FAT (or something like that), IIRC, making it easier to recover from the format. My MS-DOS 5.0 manual says that with the /U, FORMAT "Destroys all existing data on a disk", whatever that means.

DEC BA42 Storage Expansion boxes available, Bristol UK

by coredump＠gifford.co.uk

I have a few DEC BA42 Storage Expansion boxes available here, with full-height 5 1/4 inch SCSI hard disks in them. I think they're about 300 to 600Mb each. They're suitable for the DECStation 5000 (MIPS) systems. Free to anyone who can collect them from North Bristol (UK). E-mail me for full details of what disk(s) are in what boxes. -- John Honniball coredump(a)gifford.co.uk
