The QL's [[Central processing unit|CPU]], ZX8301 and ZX8302 [[Application-specific integrated circuit|ASICs]] and Microdrives form the basis of [[One Per Desk]] (OPD). Built by [[International Computers Limited]] (ICL), it was also marketed by [[BT Group|British Telecom]] as the [[One Per Desk#Merlin Tonto|Merlin Tonto]] and by [[Telstra|Telecom Australia]] as the [[Computerphone]].

The result of a three-year collaboration between Sinclair Research, ICL and British Telecom, the One Per Desk adds a [[telephone handset]] at one end of the keyboard, and rudimentary [[Computer-Telephony Integration]] (CTI) software.<ref>{{cite web|url=http://www.old-computers.com/museum/computer.asp?c=275|title=ICL OPD One Per Desk|work=OLD-COMPUTERS.COM|access-date=2008-04-21}}</ref> This machine interested a number of high-profile business customers, including certain divisions of the former [[HM Customs & Excise|UK Customs and Excise Department]], but its success was generally limited. In the late 1980s they were used in bingo halls to allow a country-wide networked bingo game.<ref>{{cite web|url=http://www.binarydinosaurs.co.uk/Museum/icl/opd.php|title=ICL OPD|work=Binary Dinosaurs|access-date=2008-04-21}}</ref>
