2 x 16-bit (LPU,[3] PPU) 3-chip hybrid processor with BPC, IOC and EMC Enhanced option 2xx: 1 x bit-slice processor (LPU) 1 x 16-bit hybrid (PPU) 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.

[4][5] The attached HP 98770A color display enabled the color graphics with its own CPU and separate power supply, a vector generator based on the AMD2900 bit-slice architecture, graphics memory with three planes of 32 KB each, the connection interface to the mainframe consists of a direct data bus attachment, and a light-pen logic.

[6] The display showed 8 soft keys on the lower end of the screen, 39 alignment controllers behind a door enabled fine tuning of color convergence.

[1] The speed of the builtin BASIC language was accomplished by implementing time critical parts of it in CPU microcode.

[1] A builtin tape cartridge device with a capacity of 217 kB and transfer speed of 1440 bytes/s enabled storage of data.
