The 820 was codenamed The Worm because Xerox saw Apple Computer as its main competitor; "InfoWorld" reported that Apple delayed and redesigned a computer under development to better compete with the 820. While less expensive than dedicated word processors such as the Xerox 860, the 820 was expensive and slow compared to personal computers; one month after its release, the $1,795 Osborne 1—faster, portable, and with bundled software worth more than $1,000—appeared, while Xerox charged $200 for the required CP/M software. The 820 did not use Xerox PARC's sophisticated technology that influenced the Apple Macintosh.
