 The initial model was "an IBM Copier III to which a laser imaging system and associated electronics have been added" and could print up to 36 pages per minute.The Model II, subsequently introduced, had double the performance, and by late 1982 was considered by Hewlett-Packard as competing against the HP2680A laser printer.As envisioned, an extension released a year later by a third party enabled "6670 .. terminal users (sic; to) send and receive data directly from other 6670s" in what the "New York Times" described as (a form of) electronic mail.
