I remember the first computer that my father purchased for our family. It was an early Pentium based Dell of some model or another. The aforementioned computer most likely came with Dos 6.22 pre installed.
Pre-Windows 95 we cycled that computer to my mothers business computer and my father bought our family. This computer also came with MS Dos 6.22 preinstalled which we upgraded to Windows 95. It wasn’t to much longer after the upgrade from Dos 6.22 to Windows 98 and then from 98 to Windows 98 Second Addition.
