Background: I built my first computer with a soldering pencil in 1977, then founded a computer company in 1979 selling Zenith, Kaypro and Morrow computers. In 1984 we began manufacturing our own PC clones designed for quick and cost-effective component upgrades, winning multi-year contracts with corporate and government agencies. In those days, rapid technology advancements led to frequent upgrades in our aggressive upgrade program so these components experienced only short term use. To keep our upgrade program prices low, we allowed credit for the removed components. Consequently, I ended up with a warehouse full of vintage computer components, all safely boxed and undisturbed for decades. Now is the time to retest and offer these vintage components to retro gaming and vintage computer enthusiasts and collectors.
