I have been working with computers for the past five years, starting fromt he scratchy XTs and up to the newer Pentiums.  I also have been experimenting with new peripherals, such as SCSI, PCMCIA and networks.  I generally am concentrated in desktop publishing and image enhancing - both graphics and images.  I know more about troubleshooting than most technicals here in my country, and it came from hundreds of hours of hands-on experience.
