Sistema 700 was a personal professional microcomputer, introduced by the Brazil computer company Prológica in 1981.[1][2][3][4]
General information
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.[5][6][7][8]
Its operating system was DOS-700, a version adapted by Prologica's software engineering department from the CP/M-80.[9][10]
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.[5]
Models
- Sistema 700 (1981 - vapourware)
Initial model announced in 1981, but never went into production.[1]
- Super Sistema 700 (1981)
Final version with graphite-colored cabinet and rounded contours.[1]
Data Storage
Data storage was done in audio cassette.[5] Audio cables were supplied with the computer for connection with a regular tape recorder.[5]
Accessories
P-720 Printer.[11]
