This should improve response, especially if you are on a slow network (like ppp/slip) The diy_efi WWW server is still running and waiting for additional material. The WWW server is fully functional but is still in its infancy and desperately needs more information. If you have written anything up to do with EFI or have references about pertinent articles or know of any supliers of material required for building EFI systems (sensors, electronics, software) send them to me. If there are any projects which you are interested in pursuing or are working on, send me a writeup or a short note. Or if you want to provide information about yourself (currently, there are two entries) send that in as well. If you are not connected directly to the Internet, you can still contribute material by sending it to me and I'll insert it into the WWW home page. What is WWW and how do you access it? --------------------------------------- WWW stands for the World Wide Web. Its a protocol that allows "documents" to be accessed anywhere by supplying the WWW server's address on which the document resides and a document name. Basically, you use a WWW viewer to connect to a WWW server. Usually, the documents retrieved are in html (HyperText Markup Language) format which allows you to do simple page layouts and formatting, include inline images and have links to other documents on the internet. By clicking on a link, you essentially go to the document it points to. The most common WWW viewer is Mosaic. It requires a machine with graphics capability and a mouse. An alternative to Mosaic is lynx which runs on a simple character terminal. I've made both Mosaic and lynx available through anonymous ftp at ftp.cpsc.ucalgary.ca in pub/WWW. All I have is source for UNIX machines. The reason I didn't include binaries is because both programs need to know where their configuration files reside and that is very system dependent. If you can't compile on your UNIX machine, let me know and we'll arrange something. I will make binaries for DOS machines and Macs available soon. For those not familiar with anonymous ftp, see further down. To use WWW, you start up a WWW viewer (like Mosaic) and give it a name of a WWW server and the document you want to retrieve. For example, to connect to the diy_efi WWW server you would do this: % Mosaic http://www.cpsc.ucalgary.ca/~fridman/diy_efi This starts up Mosaic, and requests from the server www.cpsc.ucalgary.ca a file called ~fridman/diy_efi. Unfortunately, you need direct access to the Internet. In other words, if you get this mail group through an e-mail supplier like CompuServe, America Online, GEnie or any of the others, you will not be able to access any WWW documents. Its best to talk to your provider and ask them if they offer this service. If you are in doubt whether your machine is connected to the Internet, try "pinging" some well known host (like apple.com). All UNIX systems should have a command called ping ("man ping" will tell you where it is). DOS machines running network software should have it as well. I don't know about Macs. If ping returns with a negative message, you might not be on the Internet or some site upstream is blocking your access to it. Note that just because you can get e-mail from anywhere, does not mean you can reach anywhere with other tools (like Mosaic, ping or telnet). Using Anonymous FTP ------------------- 1. ftp to the machine ftp.cpsc.ucalgary.ca 2. login as the user ftp 3. give your email address at the password prompt 4. change directory (cd) to pub/WWW 5. issue the "ls" command to get a listing of whats there 6. when you have found what you want, type "bin" to transfer in binary mode 7. type "get file_you_want" to retrieve the file 8. type "exit" Welllll, if you managed to read this far, I hope you found something useful here. If you have other questions, let me know.

I'm not sure who perfected them, NGK makes most of them. The ones I was using in 1992-1993 (NGK's repackaged by Horiba) cost $900 each and had a working life of about 200 hours. I'm pretty sure the price has come down some since then. -- Jonathan R.
