The 9845C, first mentioned in the sales brochure from January 1980, introduced in the December 1980 issue of the HP Journal and with first appearance in the HP Catalog from 1981, was the top-of-the-line model of the 9845 series, and it was the very first HP computer supporting color. Simply said, the 9845C brought color into the 9845 series.

The HP 9845C from Hewlett-Packard was one of the first desktop computers to be equipped with a color display and light pen for design and illustration work. It was used to create the color war room graphics in the 1983 movie WarGames .

Welcome to the HP 9845 preservation project. This site is dedicated to one of the most fascinating pieces in computing history, the Hewlett Packard 9845 computer. The HP 9845 opened a complete new line of dedicated computers, based on one single philosophy: to bring as much computing power as possible to the desktop.

The 9845C was introduced in 1980. It was the first computer from HP with a color screen. The 13-inch screen could display 4,913 colors. It also included both tape drives, the internal printer and a light pen. The monitor for both the 9845C and 9845T had eight programmable function keys.

The 9845A got a big success. HP's Calculator Product Division (CPD), who were responsible for the full 98x5 line, moved from Loveland to the newly built Fort Collins Division and renamed to Desktop Computer Division (DCD), which rapidly produced successors like the 9845B and the 9845C, becoming even more successful.

HP 9845 introduced first as a monochrome (9845A/S), then a high-performance monochrome (9845B/T) and a high performance color (9845C /T) model. The 9845 came with one tape drive, and optional second tape drive and 80 column wide thermal printer integrated into the base under the pillar-mounted display unit.

2013年6月29日 · The Hp 9845C, introduced in 1981, was the top-of-the-line model of the 9845 series, it was the very first HP computer supporting color and it was capable of tremendous computer graphics. It offered hardware accelerated vector drawing and polygon fill features, and supported fast matrix operations for rendering 3D models.

The 9845C models had a color monitor with a 13 inch CRT that was capable of displaying 4,913 colors, vector writing and also had an interactive light pen. The light pen was made optional in 1983. All "C" models had the graphics capability. In 1983, HP also added a new high performance bit slice CPU as option 200.

The 9845C was the first color computer I ever saw. I used the 9815, 9825, and 9826 (which had a floppy drive instead of tape, I think) for data collection and analysis, but the lucky guy down the hall managed to get his dept to pony up for the 9845C!
