In the summer of 1993 I was sent an OPD Rompack with curious circuitry and programming. It turned out to be an early version of the mythical One Per Desk Basic Compiler, thought to have never been produced. The program was unstable but did work. No documentation was included. On examinging the ROM contents, the legend 'Tony Cheal Computer One' was detected. Computer One was located in Cambridge and ceased trading probably in 1988. I checked in the Cambs telephone book and found an A.Cheal. As the phone was constantly connected to a computer or Fax I had to visit. Tony was at first not too pleased to be found. After he realised I was harmless and non-official he was very helpful. Computer One worked extensively on software products for the Sinclair QL and were asked by ICL to produce the Compiler. Curiously the compiler was not exclusively based on ICL Basic. The chosen BASIC was MC BASIC produced by MetaComCo who did the Cross-compiler system. Tony and his team took nearly 2 yrs to finalise the product. Although it started as a Computer One project, after the company ceased ICL funded the development with Tony as a private contract. It appears that the main reason for completing the project was for a company in the U.S.A. who had a Telesales program written in MicroSoft BASIC that they wanted to run on the OPD. Presumably ICL thought the software would improve sales there. Running under BASIC the program was too slow, hence the need to compile. The compiler was completed with, in the later stages, copies being sent using the OPD and the Interfile facility on the OPD to the states for test. Tony says he never had a comms failure during this process. On completion the Compiler consisted of Compiler, Assembler, Monitor and Editor. Tony very kindly gave me all his stock of equipment and software and allowed me to copy his entire workbook and Correspondence.
