There were many personal business applications available for the CPC6128 running under [[CP/M]]-80. To name a few, [[WordStar]] for word processing, [[Multiplan]] and [[SuperCalc 2]] for editing spreadsheets, [[DBase II]] for making databases as well as ... Notice, that there were also more than 13 high level languages for research and development were typical personal business applications that were ([[Programming software]]) available for the CPC6128 running under [[CP/M]]-80. However, a CP/M-80 application that could be used for research and its GUI as well, dealing with the personal or the family budget was missing (..?)development. <br>
'''COSMOS''' is a personal '''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]] 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>
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]], 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 quit the application. <br>
Upon installing COSMOS in drive B or HD20 it is suggested to execute COSMOS using all the available extra RAM (no RAM load minimization) and to use a new empty boot disk in drive A as the redundant disk (user level software RAID-1 operation).

'''Boot CP/M using the original COSMOS disk and execute A>SETUP.COM.''' <br><br>
Upon installing COSMOS in drive B or HD20 it is suggested to execute COSMOS using all the available extra RAM (no RAM load minimization) and to use a new empty boot disk in drive A as the redundant disk (user level software RAID-1 operation). A full annual project of COSMOS, including the user attachments, the user block of invoices, the summary files as well as the user agenda notices requires minimum 350 KB of disc space. <br><br>
