Anyone have experience or know for a factor of a Bachelor's degree program that teaches computer hardware and software in a logical order and comprehensively?

Yes, that's pretty much how I set it up, except I don't publish shares on Windows machines; I use samba instead. The MS client does everything I want to do with DOS, and you can upgrade the support for NICs by adding drivers, too. -- Pete Peter Turnbull Network Manager University of York

Nope, I used the "Microsoft Network Client 3", which comes as a couple of DOS disks. I seem to remember having to update one of the files, and add a driver from a 3Com disk. Even so, it only took an hour or so to download and set up, including at least one false start, and some messing with HIMEM. I spent maybe an hour more messing with things to save as much space as possible. If anybody wants to try it, I bookmarked the webpage I found most helpful: http://www.windowsnetworking.com/j_helmig/dosclnt3.htm IPX/SPX are banned from my networks, so obviously I only installed the TCP/IP stuff. -- Pete Peter Turnbull Network Manager University of York

I built a similar setup a few months ago, but I used the Microsoft TCP/IP stuff on top of DOS 6.22. It was easy to set up, and now I have telnet, FTP, ICMP (some stacks don't support that), and the whole thing uses DHCP and mounts drives from my Samba server. -- Pete Peter Turnbull Network Manager University of York

Slightly OT: tips for fabricating with plexiglass?

They're all acrylic resins, but while in my possibly limited experience Perspex and Lucite seem to be trade names for much the same stuff, Plexiglass seems to be more brittle. -- Pete Peter Turnbull Network Manager University of York

Slightly OT: tips for fabricating with plexiglass?

by news＠computercollector.com

Thanks to all for the good advice. I don't own a drill press, and I'm not certain about which type of plastic it is (lexan, plexi, etc.) -- I used the term 'plexiglass' generically -- and I'm storing it at my father's house so it is not handy for me to check right now. Avoiding fabrication during the cold weather will also be tough, as his workbench is in the garage, and it's very cold here in New Jersey (there is no space to work on projects like this here in my tiny apartment). Maybe I'll plug in a space heater in his garage before I start drilling and such. When the project is finished (hopefully in a couple of weeks) I will post a note about it here, photos on my web site, etc. Evan ===== Tell your friends about the Computer Collector Newsletter! -- It's free and we'll never send spam or share your email address -- Publishing every Monday(-ish), ask about writing for us -- Mainframes to videogames, hardware and software, we cover it all -- W: http://news.computercollector.com E: news(a)computercollector.com -- 653 readers and counting!

another way to look for old stuff on the 'net

by mapleleafman＠gmail.com

There was a discussion here in the latter part of December about old sites on the web, someone asked about whether anyone had saved an old Google page. Anyway, here's a link to a site that has a massive archive of old web pages, they say they have 100 terabytes of material with 10 billion web pages saved : http://web.archive.org/collections/web.html Some of you will know about the site but others may not. I've done searches for the Apple site (now that I'm really into macs) as well as IBM and both Ebay and Google. The Ebay pages that come up still have all of the listings on them but when you try to click any individual link, you get a 'delisted' page. But the listings are still interesting. The Apple site dates back to when OS 8.6 was the cutting edge. Doesn't seem to be anything before 1996 but then there wasn't a whole lot out there before that anyway. Point of all this is that if you had an old site saved as a favorite, an owner's manual site for instance, you should be able to put in the url and get an archived copy of the old site. I know people who have been able to recoved lost/hijacked sites using this url and I hope some of you find it interesting. If something has disappeared on the modern web, it might still be at this site in the archives. BM

"Cold heat" soldering?

by jfoust＠threedee.com

I'd seen the commercials for this instant-on battery-powered soldering iron and wondered if I should add it to my tool box. I saw this FAQ on Thinkgeek: http://www.thinkgeek.com/files/FAQ040504.pdf which made me think twice: Q: What kind of soldering projects is this tool recommended for? A: Based on the specifications mentioned above, we recommend this tool for most electrical projects (such as wires 18-24 AWG), small jewelry repair, and larger electronic projects. We do not recommend it for soldering of large metallic components that require a lot of heat transfer or for soldering sensitive electronic components that may be damaged by fast-rising temperatures or high electrical current. (Momentary high-amperage current will be created during active soldering.) Q: What is the spark I see sometimes during soldering? A: The spark (arc) is caused by the passing of electrical current from one half of the tip to the other. Although in testing the tool’s spark did not damage any electrical or electronic components, we recommend caution when soldering sensitive components. Also, ensure that the tool is not used in flammable or explosive environments. - John

Tandberg X-terminal software?

by toresbe＠ifi.uio.no

Hello! I just aquired not only a very cool TDV2200 (which is currently printing with its matrix printer the entire bash manpage, muahahaha, one hour and counting), but also a Tandberg X-terminal - this terminal needs a boot image that is to be served to it at startup. Apparently this came on a CD-ROM - does anyone have the boot files or the CDROM? TIA! -- Tore S Bekkedal <toresbe(a)ifi.uio.no>

Slightly OT: tips for fabricating with plexiglass?

This computer will be on display > as some public events, so the final appearance is very important. The biggest problem is likely to be as the drill bit breaks through. If you look at the end of a twist drill you'll see that the centre doesn't cut in the same way as the edges, and it's the force of the centre distorting the plastic as it breaks through that causes cracks. The other problem is if you don't have enough control of the drill, and the bit "snatches". Tips: use a really sharp bit drill a small pilot hole first, and maybe enlarge that to some intermediate size so the pilot hole is a little larger than the point of the final drill put the plexiglass on a smooth block of wood or spare plexiglass, hold it down *firmly*, and drill through into the wood (make sure there's no swarf from earlier holes trapped between the plexiglass and the sacrificial material) run the drill slowly enough to avoid generating heat, but keep just enough pressure on it to ensure it keeps cutting, and doesn't rub use a drill press, not a hand-held drill practice on a piece of scrap first I drill lots of plastics, some very brittle, this way. -- Pete Peter Turnbull Network Manager University of York
