I do all of my work from home unless I'm installing hardware in someone's business or home. My partner, Don and I do tech support for a number of small businesses here in the valley and there's not much we won't do as long as it's legal. We do a lot of notebook hard drive replacements, virus removal and new system setups. Both of us spent over 15 years in the product support business and we couldn't get away from it if we wanted. Once you've done tech support and your friends know what you did for a living there's no getting away from it. We're also a test site for HP color printers so I now have a nice collection of color printers to work with.
My dad had a darkroom in our home and did B&W developing so I learned photography at an early age. At HP, I worked in a photo lab and was trained and certified by DuPont in the processing of silver halide films that we used to produce micro-circuitry. We started with manual cameras and switched to digital in the late 80s long before anyone knew what a digital photo was. I took care of 2 laser imaging systems that cost a quarter million each. Later, I supported the Scanjet products, color printers and digital cameras as the color standards developed (CGA, EGA, VGA, SVGA, HD, etc).
