Some hardware made by [[KDS Electronics]].
* The Communicator might be a modem (according to a review in the Danish Amstrad Magazine [[Amstradbladet 1985, Issue 6]] page [[:File:Amstrad Bladet8506033.jpg|35]]). Possibly a revision of the [[Mini-Max Modem]] from KDS.
* It might also be a Serial and Parallel interface being made years later in 1992 (according to http://www.retroisle.com/amstrad/cpc/Articles/hwlist.php).
The above descriptions do more or less conflict with each other, the danish article from 1985 sounds a bit more trustworthy, but maybe both descriptions are correct (and the whole package consisted of both a modem, bundled with serial/parallel interface).
