Sistema 700 was a personal professional microcomputer, introduced by the Brazilian computer company Prológica in 1981.[1][2][3][4]
General information
[edit]The machine was based on the Intertec Superbrain and had similar characteristics:[5][6] based on the Zilog Z80A 8-bit, 4MHz microprocessor, it had 64 KiB RAM configuration and two 5-1/4" floppy disk drives with capacity for up to 320 KiB of storage.[7][8][9][10]
Its operating system was DOS-700, a version adapted by Prologica's software engineering department from the CP/M-80.[11][12]
It achieved relative commercial success in financial, database and engineering applications. Due to the compatibility with the popular CP/M system, various applications like Fortran ANS, BASIC compiler, COBOL ANSI 74 compiler, Algol, Pascal, PL/I, MUMPS/M, RPG, Faturol C could be used. Other applications like word processors (WordStar), spreadsheets (CalcStar) and databases (DataStar and dBase II) were also compatible. Your applications could be programmed in BASIC, Cobol-80 and Fortran.[7]
