[[WordStar]] for word processing, [[Multiplan]] for editing spreadsheets, [[DBase II]] for developing making databases as well as more than 13 high level languages for making customized applications research and development were typical personal business applications that were running in CPC available for the CPC6128 under [[CP/M]]-80. However, a CP/M-80 application dealing with the personal or the family budget was missing(..?). <br>

'''COSMOS''' is a personal COSt MOnitoring System '''COS'''t '''MO'''nitoring '''S'''ystem written by [[KSL|KSL]] 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 projects developed for CP/M-80. COSMOS runs under the [[Dobbertin]] 63 KB TPA version of [[CP/M|CP/M 2.2]] (the [[Dobbertin]] 63 KB TPA version) and 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. <br><br> COSMOS can be used to edit the daily income, plan the monthly expenses and perform trial and error analyses in order to maximize the annual profit. COSMOS supports any external high capacity drive (up to 800 KB), the [[Dobbertin Memory Expansion]] (up to 512 KB), the [[Dobbertin Harddisc]] (20 MB HD), the [[Amstrad Serial Interface]], any dot matrix printer, the [[CTM640/CTM644]] (for the 16-color screen saver) and the [[AMX Mouse]]. <br>

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 an external disk drive (up to 800 KB) and supports the 512 KB [[Dobbertin Memory Expansion]], the 20 MB [[Dobbertin Harddisc]], the [[Amstrad Serial Interface]], a dot matrix printer (if any), the [[CTM640/CTM644]] color monitor for the 16-color screen saver and the [[AMX Mouse]]. <br> By using the setup installation utility of COSMOS 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 escapequit the application. <br>Upon installing the application COSMOS in drive B or HD20 it is suggested to execute COSMOS using all the available extra RAM (no RAM load minimization) and using to use a new empty boot disk in drive A as the redundant disk (user level software RAID-1 operation).
