Sistema 700 was a personal professional microcomputer, introduced by the Brazilian computer company Prológica in 1981.[1] [2] [3] [4]
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]
Initial model announced in 1981, but never went into production.[1]
Final version with graphite-colored cabinet and rounded contours.[1]
Data storage was done in audio cassette.[7] Audio cables were supplied with the computer for connection with a regular tape recorder.
P-720 Printer.[13]
