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.

The HP 9830A was the most powerful model of the original 9800 series calculators. It greatly blurred the lines between traditional computers and calculators due in part to its use of the BASIC programming language and options such as terminal emulation and a hard disk drive.

The 9830A programmable calculator was arguably Hewlett-Packard’s first desktop PC, which would also make it one of the earliest devices in the history of desktop computing.

Beginning in th early 1970s, HP released newer, more advanced systems to replace the aging and limited HP-9100A. These include the HP-9810A (model 10) in 1971, HP-9820A (model 20) in 1972, and the HP-9830A (model 30) in 1973. The HP-9830A is the most powerful of the 9800 series of calculators. Calculators?

Jul 31, 2023 · What was the Hewlett Packard 9830A? The Hewlett Packard 9830A — often abbreviated simply as the HP 9830A — was a remarkably powerful calculator with a ROM and processor that served as an early predecessor to the modern-day computer.

The Hewlett-Packard 9830A is a desktop-sized, all-in-one computer, released in 1972. It was usable out-of-the-box, booting to BASIC (stored in ROM) immediately at power-up. It incorporates a 16-bit processor, full alpha-numeric keyboard, 32-character alpha-numeric LED display, and digital cassette tape drive, in one package, with ROM firmware ...

A built-in tape cassette unit is included in the mainframe in place of the magnetic card reader used in previous HP calculators. The I/O structure of the 9830A is identical to that of the 9810A and 9820A, so all the 9800-Series peripherals operate with the 9830A.

HP 9830 notes: Memory was reallocated from registers to program as needed. Because lines where highly variable in length there is no fixed maximum # of line; Batch BASIC option allowed the machine to accept and execute BASIC programs on marked or punched cards. Terminal ROM allowed the machine to act as a terminal.
