There were many serious business applications available for the CPC6128 running under [[CP/M]]-80. [[WordStar]] and [[Protext]] for word processing, [[Multiplan]] and [[SuperCalc 2]] for editing spreadsheets, [[DBase II]] for making databases, [[Cashbook Accounts]] for book-keeping tasks, were such applications to name a few. Furthermore there were many high level languages ([[Programming software]]) available for the CPC6128 running under CP/M-80 that were used for research and development. <br><br> '''COSMOS''' is a personal '''COS'''t '''MO'''nitoring '''S'''ystem developed by [[KSL|KSL]] for CPC6128 which runs under CP/M-80. It is a personal business application similar to the MSDOS-era PC applications and one of the most recent (2020) projects developed for CP/M-80. Unlike most business applications for CP/M, COSMOS is built upon the '''mouse based graphics user interface ''' as pioneered by Xerox at Palo Alto and popularized by Apple with the Lisa and Macintosh computers. COSMOS can be used on an everyday basis in order to edit the daily income, plan the monthly expenses and perform trial and error analyses aiming at maximizing the annual profit. COSMOS requires the [[Dobbertin]] 63 KB TPA version of [[CP/M|CP/M 2.2]] and an external disk drive (min 360 KB). Moreover, it supports the 512 KB [[Dobbertin Memory Expansion]], the 20 MB [[Dobbertin Harddisc]], the [[Amstrad Serial Interface]], the Amstrad Parallel [[Printer Port]], the [[CTM640/CTM644]] color monitor for the 16-color screen saver and the [[AMX Mouse]]. In addition to its main functions, COSMOS also contains the latest version of [[ASCII Tools]] in order to deal with the COSMOS large output files. By executing the setup installation utility (A>SETUP) that is included in the COSMOS original disk, the user can initialize any annual project or start a temporary project in order to become familiar with the COSMOS user interface and functions. As far as the controls are concerned, '''Cursor keys''' or '''Mouse''' can be used in order to control the pointer. '''[F0]''' key simulates the left button of the mouse, whereas '''[F.]''' key simulates the right button of the mouse. Left button can be used for (Yes), whereas the right button can be used for (No),(Next) or (On-Board) help. ESC key can be used to quit. <br><br>
