At the time DOS was being introduced, one of the biggest CP/M applications was Visicalc, a spreadsheet application. Many of the people buying Commodore and other "personal computers" of the day were accountants/book keepers using Word Star and VisiCalc. The spreadsheet users/accountants wanted an adding machine type keypad. DEC created a data entry form numeric keypad because that was how order entry, inventory, etc. applications used it. Two completely different markets.
