The One Per Desk, or OPD, was an innovative hybrid personal computer/telecommunications terminal based on the hardware of the Sinclair QL.〔(The Register: Sinclair's FORGOTTEN Australia-only micro revealed! )〕 The One Per Desk was built by International Computers Limited (ICL) and launched in the UK in 1984. It was the result of a collaborative project between ICL, Sinclair Research and British Telecom begun in 1981, originally intended to incorporate Sinclair's flat-screen CRT technology. Rebadged versions of the OPD were sold in the United Kingdom as the Merlin Tonto and in Australia as the Telecom Australia Computerphone. == Hardware == From the QL, the OPD borrowed the 68008 CPU, ZX8301/8302 ULAs, 128 KB of RAM and dual Microdrives (re-engineered by ICL for greater reliability) but not the 8049 Intelligent Peripheral Controller. Unique to the OPD was a "telephony module" incorporating an Intel 8051 microcontroller (which also controlled the keyboard), two PSTN lines and a V.21/V.23 modem, plus a built-in telephone handset and a TI TMS5220 speech synthesiser (for automatic answering of incoming calls).〔(【引用サイトリンク】title=ICL OPD — One Per Desk )〕〔(【引用サイトリンク】title=A full technical breakdown of the OPD by Murray McCabe )〕 The OPD was supplied with either a 9-inch monochrome (white) monitor or a 14-inch colour monitor. Both monitors also housed the power supply for the OPD itself. Later, 3.5" floppy disk drives were also available from third-party vendors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「One Per Desk」の詳細全文を読む スポンサード リンク
