'''COSMOS''' is a personal '''COS'''t '''MO'''nitoring '''S'''ystem programed by [[KSL|KSL]] for the CPC6128 and [[CP/M]]-80 operating system, which was the industry standard of the late 70s - early 80s. This budget monitoring system is a business application similar to the MSDOS-era PC applications and one of the most recent (2021) projects developed for CP/M. Unlike most 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. '''Nowadays''', COSMOS can be used on an everyday basis (using [[CaPriCe]] or [[WinCPC]] or a real CPC) in order to edit the daily income, plan the monthly expenses and perform trial and error analyses aiming at maximizing the annual profit. <br><br> COSMOS has been developed on the basis of the hardware peripherals that were (contemporary) available for the CP/M and the CPC6128: the 512 KB [[Dobbertin Memory Expansion]], the [[ParaDOS]] or [[X-DDOS]] ROMS for the external (800 KB) floppy drive, the 20 MB [[Dobbertin Harddisc]], the [[Amstrad Serial Interface]], the Amstrad Parallel [[Printer Port]], the [[CTM640/CTM644]] colour monitor and the [[AMX Mouse]]. COSMOS (165 KB) has been also developed on the basis of the software that was contemporary available for the CP/M, like [[MicroScript]] (142 KB), [[WordStar]] (706 KB), [[Protext]] (406 KB), [[Multiplan]] (208 KB), [[SuperCalc 2]] (240 KB), [[DBase II]] (272 KB), [[DR Draw]] (235 KB), [[DR Graph]] (306 KB), [[MAXAM]] (206 KB) as well as other [[Programming software]] for CP/M-80. COSMOS includes its own [[GSX]] routines and requires the [[Dobbertin]] version of CP/M 2.2 (v1.2) which provides 63 KB TPA, supports the RAM disk and the 20 MB hard disk. <br><br>
In addition to the command and chain files, COSMOS original disc also contains the CP/M 2.2 (v1.2) boot sectors as well as an installation utility. By executing the latter utility (A>SETUP) the user can initialize any annual project or start a temporary project in order to become familiar with the COSMOS user interface and functions. 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 CP/M 2.2 (v1.2) boot disk in drive A as the redundant disk. 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. Notice that COSMOS also contains the latest version of [[ASCII Tools]]. <br><br> 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>
