Gary Thuerk, a Digital Equipment Corporation marketer, composed a message promoting the DECSYSTEM-20 computer. The message promoted two upcoming product presentation of the DECSYSTEM-20 accessing the ARPANET. The reaction to the message was swift and highly negative, including one who claimed that the message shut down his system.

             Dell Computer Corporation is founded by Michael Dell, running the direct-to-order PC company from his dorm room. Dell, Inc. eventually became the largest manufacture of PCs in the world for many years. It is currently surpassed by HP and Acer.  

2000 – 15 Years of GeoCaching
             Up until May 1, all GPS signal were scrambled for protection. President Bill Clinton announced they would be turning off the Selective Availability (SA) because it didn’t propose a greater threat. But it also gave geeks something new to play with. But what to do?

Dave Ulmer ultimately started the GeoCaching phenomenon. He did a bunch of trinkets out in the woods of Portland, Oregon. He then went to the USENET group sci.geo.satellite-nav and started “if you take something, leave something.”
