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 [[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 RAM expansionMemory Expansion]] (up to 512 KB), the [[Dobbertin hard diskHarddisc]] (20 MB HD), the serial RS232C interface[[Amstrad Serial Interface]], any dot matrix printer, the CTM color monitor [[CTM640/CTM644]] (for the 16-color screen saver) and the [[AMX Mouse]]. <br>
