Wayback Machine™ Screen Captures of RF Cafe

This is really cool! The Internet Archive Wayback Machine™ captures images of webpages at random intervals and stores them on a server where you can see what a page used to look like. Go to the above link and type in the address of your favorite website (maybe your own) and then click on some of the captured screens. Images are not stored, however, so it will display the little red "x" in the place of all images that are not still in the same location on the website. In some cases, clicking on a link takes you to another page in your website. It's a trip down virtual memory lane. Here are just a few from RF Cafe - we've come a long way, baby!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
