customers, in Local Government and Ministry of Defence sectors, used statistics applications on OPD systems to view graphical representations of mainframe reports. Once again, the integral V.23 modem was used to download from the mainframe. Merlin Tonto British Telecom Business Systems sold the OPD as the Merlin M1800 Tonto. BT intended the Tonto to be a centralised desktop information system able to access online services, mainframes and other similar systems through the BT telephone network. The Tonto retailed at £1,500 at launch. OPD peripherals and software ROM cartridges were also badged under the Merlin brand. BT withdrew support for the Tonto in February 1993. The name Tonto was derived from "The Outstanding New Telecoms Opportunity" A data communications adapter was introduced for the Tonto as a plug-in option or fitted on new units, providing a standard RS423 interface for use with mainframe computers or data communications networks, permitting the use of the Tonto as a VT100 terminal. A separate VT Link product provided support for VT52 and VT100 emulation for mainframe access over dial-up connections. Work on the Tonto influenced the design of a follow-on product by BT's Communications Terminal Products Group and Rathdown Industries known as the QWERTYphone, this aiming to provide the telephony features of the Tonto at "a much lower cost and in a more user-friendly manner". ComputerPhone Aimed at the "office automation" market and seeking to integrate computing and telecommunications technology, combining support for both voice and data, the One Per Desk product was perceived as the first of its kind designed to meet the needs of managers, who would be relying on old-fashioned paper-based practices to perform their "complex and heavy workloads" involving a variety of ongoing activities including meetings, telephone calls, research, administration and numerous other tasks. Such potential users of information technology had apparently been ignored by office automation efforts, and personal computers were perceived as "exceeding most managers' requirements". The ComputerPhone attempted to sit between more specialised telephony devices and more advanced workstations, being marketed as an "executive" workstation in Australia, somewhat more towards middle management in New Zealand. Advertisements emphasised the telephony, office suite, desktop calculator, videotex, terminal and electronic messaging capabilities. MegaOPD An enhanced version of the OPD was produced in small numbers for the United States market. This had a 68008FN CPU, 256 KB of RAM as standard, an RS-232 port and enhanced firmware.
