I am a retired computer consultant specializing in PC-compatible computers.
Check out my Library of utilities. Many of my programs and utilities have long been available on CompuServe and have variously made their way around other Internet depositories, but can now be downloaded from here as well.
The Year-2000 crisis became a hot topic worldwide in 1998, but had been known to a relatively small group of techs several years earlier. My hardware test program, 2000TEST, was originally written in 1996. While the crisis with software was real, the problem with PC hardware was often blown out of proportion. 2000TEST was used by thousands of people to check their PCs, to understand the real nature of the problem and to wade through the mass of hyperbole and misinformation.
Other projects have included setting up computers to boot multiple operating systems. I first began dual-booting in 1986 with DOS 3.3 on a 20 MB hard disk, configured with work and personal environments. In ensuing years I was soon triple-booting and then looking for ways to multi-boot even more operating systems. After a lot of research and trial-and-error, I finally settled on a successful solution. I've documented my multi-booting procedure here, which I still use today to boot everything from DOS to Windows 10.
In the past decade or so, I've switched to using virtualization in lieu of alternate boot partitions to run multiple operating systems. I've found it an excellent method for isolating internet browsing sessions, as well as testing new software before committing it to my "real" machine.
In 2004 the Dell Computer company began shipping XP-equipped consumer PCs with a proprietary factory restore feature. Documentation was virtually non-existant and the feature--not particularly well designed--easily broke and malfunctioned. My investigation and treatise soon became recognized world-wide as the definitive source for information regarding the feature. Over a four-year period that page alone was regularly receiving around 2,000 unique visitors per day from exasperated Dell users.
