The Hewlett-Packard 3000 series is a family of minicomputers released by the company in 1973 after a difficult development project. It was intended to be the first minicomputer delivered with a full featured operating system with timesharing. The Hewlett-Packard Company (NYSE: HPQ), commonly known as HP, is a very large, global company headquartered in Palo Alto, California, United States. ... HP2114 minicomputer Minicomputer is a largely obsolete term for a class of multi-user computers which make up the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems (microcomputers or personal computers). ...
The early machines were based on a 16-bit custom CISC processor. Around 1988 machines using HP's PA-RISC processors shipped in volume, bringing 32 bit addressing. Binary compatibility with the older machines was (and is) maintained. PA-RISC is a microprocessor architecture developed by Hewlett-Packards Systems & VLSI Technology Operation. ...
The 3000 series operating system is called MPE and includes a built-in database called TurboIMAGE. MPE is an early 1980s era business-oriented minicomputer operating system made by Hewlett-Packard. ... IMAGE is the primary reason that the HP3000 was a success. ...
In 2003, HP discontinued 3000 series sales. All support will be terminated beginning Jan 1,2007.

The other half of the speed problem – the HP3000 Editor's loss of characters from the PET – occurred because there is a delay between the time that the Editor accepts a line of input (terminated by a carriage return) and the time it starts accepting the next line.
As mentioned before, the accuracy of the uploading is limited by the time lag in the HP3000 Editor that occurs between the receipt of one line of text and the acceptance of the next.
We thought about developing a handshaking protocol in which the HP3000 Editor would signal when it was ready to accept a new line; but this plan was discarded because it would require each line to be listed individually, and the LIST command is not capable of this.
