HP 9800 series
The HP 9800 is a family of what were initially called programmable calculators and later desktop computers that were made by Hewlett-Packard, replacing their first HP 9100 calculator. It is also named "98 line". The 9830 and its successors were true computers in the modern sense of the term, complete with a powerful BASIC language interpreter.
Chronologically, the models of the family were:
All 98x0 and 9821 systems used the same I/O interfaces. A 400 line per minute 80-column thermal line printer was designed to fit on top of the 9820 and 9830.
The success of the HP9830 led to a next generation with faster logic:
All the 98x5, with the exception of the 9805, used DC200 cartridge tapes, instead of cassette tapes. The 9825, 9831, 9835, and 9845 all used the same I/O interfaces. the 9815 had a unique I/O interface.
The HP 9800 series were developed by HP's Loveland division (Calculator Products Division), and later Fort Collins division (Desktop Computer Division). Early desktop computers were marketed as "Calculators" to make purchasing easier. At the time, some companies had different procedures for purchasing "Computers".
They spawned development of the HP Series 80 machines, including the HP 85 and HP 87, which were smaller BASIC language computers with CRT displays. They came from HP's Advanced Products Division based in Corvallis.
For a short time in the late 1970s and early 1980s there was a class of similar desktop computers, such as the Tektronix 4051, IBM 5100 and Wang 2200 - before they were replaced in the marketplace by personal computers such as the Apple and IBM PC.
