RWAP Services is run by Rich Mellor, who has been involved with computers since acquiring a Sinclair ZX81 in 1982 (the first mass home computer designed by the well-known British inventor, Sir Clive Sinclair). An adept programmer, with the ability to program in BASIC, machine code, C, HTML, Perl, MS-Access, SQL, and Ladder (PLC-5, SLC-500 and RSLogix), Rich Mellor has achieved some recognition in connection with the Sinclair QL, as a computer journalist, author and commercial programmer/tester. This ability has been put to good use to develop innovative software for the Sinclair QL and for the internet, including perl guestbooks and visitor counters, all based around modular coding techniques.
Since 1988, RWAP Services have been testing commercial software prior to release, often re-writing sections of code on behalf of the authors, in order to overcome bugs. Unlike many other software testers, RWAP Services' broad base in programming skills allows us to identify the possible causes of program errors and where incompatibilities may be software or hardware based. As an ex-solicitor, Rich Mellor's attention to detail is legendary and he is famed for producing in-depth, easy to understand, reports of programs which describe problems in detail and often contain suggested bug-fixes and improvements.
An example is when Rich Mellor joined Data Solutions as a technical author in 1998. Within a week, he was sent to assist with producing documentation for the prestigious Heathrow Terminal 3 Transfer Baggage Facility. Within two weeks, Rich had gained sufficient insight into the PLC-5 ladder language to enable him to assist with commissioning the control software and to prepare in-depth reference tables for the MMI (SCADA) programmer. Later, Rich was given the task of amending the software for Phase III of the project, carrying out all steps up to and including the Factory Acceptance Test, such that the software was installed and ready for commissioning after only one night on site.
success on the Heathrow project, Rich was asked to look at some
problematic SLC-500 code for controlling water treatment plants.
It was explained that on some specific dates, the software failed to
carry out all of its intended functions, but two software engineers had
been unable to identify the problem in the software. Within one
day of being allocated the project, Rich Mellor had identified the
problem and its solution, providing a full report to the original
software author which enabled him to implement the solution across
several existing operational sites.
In the past few years, we have specialised in developing online auction website solutions plus products specifically designed to keep retro computers and older equipment functional. We also work in conjunction with Michael Jackson Controls Limited to provide additional PLC and SCADA service support.
