Na veel gezoek heb ik toch de specificaties van de Greenpoint
telefoons (CT2 telefoon, technisch gesproken) weten te vinden.  Ze
komen uit de archieven van uk.telecom, van iemand die ze bij Motorola
had losgepeuterd. Voor 't geval dat iemand het zich afvraagt: alle
vier(!) de Britse CT2 ("Greenpoint") operators zijn reeds over de kop
gegaan.

In de specificaties is sprake van een "Silverlink 2000" telefoon. Die
dingen zijn volledig identiek met de Greenhopper 100. Vergelijk de
modelnummers maar eens (in het batterijcompartiment zit een sticker).

Veel plezier,
