'''COSMOS''' is a personal '''COS'''t '''MO'''nitoring '''S'''ystem programed by [[KSL|KSL]] for the CPC6128. It has been developed under is an application for the [[CP/M]]-80 operating system, which was the industry standard of the late 70s - early 80s. 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. This budget monitoring system is a business application similar to the MSDOS-era PC applications and one of the most recent (2020) projects developed for CP/M-80. 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. <br><br> Although the CPC6128 was sold as a colour Personal Computer, its configuration in the as received condition referred to a light Personal Computer (128 KB RAM, 180 KB FD, 80x25 text, CP/M). By adding an external high capacity disc drive, a RAM expansion, a hard disk, a serial interface as well as a mouse, the CPC6128 was turned into a competitive Personal Computer. Thus, a lot of serious business applications that were available for CP/M-80 could be executed with ease allowing the user to focus on his work and not on how to deal with the hardware limitations of the system. Typical examples of such applications were [[WordStar]] (706 KB), [[Protext]] (406 KB), [[Multiplan]] (208 KB), [[SuperCalc 2]] (240 KB), [[DBase II]] (272 KB) and other [[Programming software]]. <br><br> COSMOS supports all the hardware peripherals that were (contemporary) available for the CP/M applications of 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 for the screen saver and the [[AMX Mouse]]. In order to accomplish its task, COSMOS has includes its own [[GSX]] and requires the [[Dobbertin]] version of CP/M 2.2 (v1.2) which provides 63 KB TPA. Finally, Notice that the software also contains the latest version of [[ASCII Tools]]. <br><br> By executing In addition to the command and chain files, COSMOS setup 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) 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. 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. Notice that 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. 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> Upon installing Useful applications when working with COSMOS in drive B or HD20 it is suggested to execute COSMOS using all the available extra RAM are [[WordStar]] (no RAM load minimization706 KB) and to use a new empty boot disk in drive A as the redundant disk. Notice that a full annual project of COSMOS, including the user attachments[[Protext]] (406 KB), the user block of invoices[[Multiplan]] (208 KB), the summary files as well as the user agenda notices requires minimum 350 [[SuperCalc 2]] (240 KB of disc space), [[DBase II]] (272 KB) and other [[Programming software]]. <br><br>
