The HP 9845 was the first in a famous line of workstation systems developed by Hewlett Packard. Other manufacturers like Apollo and Sun Microsystems (they were the ones who first transferred the Xerox Parc graphical user interfaces to commercial workstations), Silicon Graphics (who developed workstations with 3D-real-time-rendering capabilities ...

HP 5061-3001 16-bit 4-chip hybrid processor used as the LPU & PPU processors in the HP 9845 series computers. Contains the BPC, IOC, EMC and AEC die. 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.

The 9845 was the first HP computer to incorporate a twelve-inch CRT screen. Previous computers had only one or three line screens. The large monitor of the 9845 made program debugging and program listing much more convenient. It also provided (optional) graphics display for the first time, with a resolution of 560 x 455 dots.

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.

The 9845 system was an amazing piece of hardware, built on state-of-the-art technology and combining the usability of a desktop calculator with the performance and flexibility of a 16-bit minicomputer system. ... including RS-232 and HP-IB. Peripherals. In addition to the internal thermal printer and tape cartridge drives, there was a large ...

The overall functionality needed for the HP 9845 did overstrain the capabilities of the NMOS-II production process in terms of chip size. So each hybrid processor comprised separate chips on one common ceramic substrate, one for instruction fetch/decoding and basic logic (the binary processor chip or BPC), a chip for I/O and stack operations ...

Re: HP 9845A vs 9845B vs 9845B/A Message #2 Posted by Tony Duell on 23 Aug 2010, 4:44 a.m., in response to message #1 by Mike. To answer the last part first, I believe you do need a monitor on a 9845 for it to work. There is some synchronisation signal sent back from the monitor, and the processors get somewhat confused without it.

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. It was intended for use in scientific and engineering environments, but ...
