The HP3000 models 30, 33, 40, 44, 42, & 48 went on to great success using what was developed in the HP300. The HP300's change to one (at the time) high speed interface HP-IB channel from HP3000's previous use of many different type internal IF cards radically changed and improved future HP system

systems that used the HP300's advanced designs: HP3000 model 30 (project name: Koala - a single card bay stand-alone box) and model 33 (project name: Toothpick - a double card bay table design) reused many of HP300's designs. The HP300 diagnostics (DUS) were ported over and used in these and future

HP Computer
Systems Division General Manager (GM), Doug Spreng, decided the file system differences between the division's money making HP3000 line and the burgeoning HP300 would keep the HP300 from being successful and killed the product. HP built two semi-truck loads of units before shutting down

home of the HP 3000 business computers (the division was later renamed
Computer Systems Division CSY). Later, the HP300 design team developed multi-user abilities, and an ahead of its time inter-unit processor interconnect that let one HP300 change registers in other inter-connected HP300's system.

The circuit boards were in a floor pedestal box, with CRT on top with built-in soft keys, and fixed keyboard protruding in front. It pioneered such ideas as built-in networking, automatic spelling correction, multiple windows (on a character based screen), and labels adjacent to vertically stacked

Later, the HP300 design team over came the first generation HP300 slower TTL circuitry with a SOS design (project name: Sizzler). Again the GM killed its release and reused its designs in a new HP3000 model 40 (project name: Cub - single card bay stand-alone box) and the model 44 (project name:

HP commonly reused the work of killed products in other product designs to save money and keep design-team morale up. The processor board and I/O boards were used in later
