Humanclock.com runs on a Radio Shack 2.4mhz TRS-80 Model 100 portable computer, using a stripped-down version of the Apache webserver software (version 100-BASIC.12 beta). The graphic files are stored on magnetic tape accessed via a modified Radio Shack personal cassette player (CAT NO. 14-1215). The webserver is powered by a 6 volt TRS-80 AC Adaptor (CAT NO. 26-3804). We take our web hosting very seriously at humanclock.com, therefore we have installed 4 "AA" batteries in the webserver in case of power failure. Whereas some battery backup systems last for only 20 minutes and cost hundreds of dollars, our power backup solution lasts for 20 hours and costs $2.49, (due to it being double coupon Tuesday). In the case of power outage however, it takes our webserver about one second to come back online, something that would take a common UNIX/NT system over two minutes.http://www.humanclock.com/webserver.html
