HP 2100

The Hewlett -Packard 1000 series was created in the 1970s computer family of Hewlett-Packard.

Precursor of HP1000 HP2100 was the computer family, whose first model was developed 2116A mid-1960s. HP offered the HP 1000 series computer, especially in the technical field with the multi -user operating system RTE (Real-Time Executive ) and the single -user operating system DOS (not to be confused with MS- DOS ) to. The first computer systems came in 1967 at purchase prices 120000-250000 Mark to market and lay about in the power range of the former competitors PDP -11 Digital Equipment or the Nova 3 / D from Data General.

Programming was done in the languages ​​BASIC, FORTRAN, ALGOL, and HP assembler. Main technical features of HP1000 were a 16 -bit CPU with a dual-channel DMA controller (that is, two DMA operations could run simultaneously ), a Memory Management Unit (MMU ) with side management and memory protection and the expandability of the memory to up to 2 megabytes. Application areas were computer graphics and simulations, and in particular operational control and monitoring in manufacturing plants. In conjunction with the upgraded operating system variant RTE -A HP1000 Calculator built since 1982 type HP1000 A ( in the variants A 400, A 600, A 700 and A 900 ) in the 1990s for laboratory data systems and as a control computer yet, particularly in range of printers used. The last HP1000 products were taken by Hewlett- Packard on 1 November 2000 off the market, the end of support for the CPUs the A400, A600 and A990 was made in 2005.

To use the sometimes very extensive individual applications that were developed on the HP1000, especially in the process control and monitoring environment, even after the end of support, the HP1000 family further, was originally developed by Hewlett -Packard, and later of the company OrgaBIT, a comfortable migration tool with the name RTE -UX developed and used in the context of migration projects. With RTE -UX HP1000 applications can be easily and quickly migrated to the Unix / Linux world and thus continue to be used.
