DOS Versions (Was: IBM PC-DOS 2.10 explorations

>MS-DOS 5.00	first version sold RETAILFred,I have to respectfully disagree here. 3.20 was sold in retail. It was packaged in the dark blue packaging which was the norm for MS at that time (after the green packaging of earlier products).  I have a copy sitting up on my shelf (in fact I have both 3.20 and 3.21). 4.00 seems to be in the grey oem package but not necessarily branded (i.e. a generic rey box included with new system purchase) . I have not seen anything MS retail before 3.20.-Ali
