I bought a scanner back in 1999, a Plustek OpticPro 9636T. It worked fine in Windows 98. Unfortunately they did not make this model when Windows XP or 2000 were released, and therefore refused to make a driver for them. I believe it’s on the premise that they would rather people buy another scanner. Geez.
My last Windows 98 machine is almost dead, so I did what any self-respecting geek would do, I hooked it up to my Linux box. It did not work out of the box with Fedora Core 2 – I had to configure some “sane” (Scanner Access Now Easy) settings first, but lo and behold, it works great! You’d better believe I will not be buying another scanner simply because Plustek wants more of my money!
