Intel SDK-86. The SDK-86 MCS-86 system design kit is a complete single board 8086 microcomputer system in kit form. It contains all necessary components to complete construction of the kit, including LED display, keyboard, resistors, caps, crystal, and miscellaneous hardware.
8086/8088 datasheet documents only base 10 version of the AAD instruction (opcode 0xD5 0x0A), but any other base will work. Later Intel's documentation has the generic form too. NEC V20 and V30 (and possibly other NEC V-series CPUs) always use base 10, and ignore the argument, causing a number of incompatibilities: 0xD5: AAM
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 [citation needed] and June 8, 1978, when it was released. [5] The Intel 8088, released July 1, 1979, [6] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM ...
During the mid-1980s NEC and Intel had a long-running US federal court case about microcode copyright. [26] NEC had been acting as a second source for Intel 8086 CPUs with its NEC μPD8086, and held long-term patent and copyright cross-licensing agreements with Intel. In August 1982 Intel sued NEC for copyright infringement over the microcode ...
The first Model 25 is powered by an Intel 8086 running at 8 MHz, roughly twice the speed of the original IBM Personal Computer. [3] A college student-oriented version of the Model 25, the Collegiate, has two 720 KB floppy drives, with a maximum RAM capacity of 640 KB, and was packaged with the official PS/2 Mouse, Windows 2.0 , and four blank ...
Version 4.0 of OMF for the 8086 family was released in 1981 under the name Relocatable Object Module Format, [6] [3] [4] and is perhaps best known to DOS users as an .OBJ file. Versions for the 80286 ( OMF-286 ) [ 7 ] [ 8 ] and the 32-bit 80386 processors ( OMF-386 ) [ 9 ] [ 10 ] [ 3 ] were introduced in 1981 and 1985, respectively.
INT 10h is fairly slow, so many programs bypass this BIOS routine and access the display hardware directly. Setting the video mode, which is done infrequently, can be accomplished by using the BIOS, while drawing graphics on the screen in a game needs to be done quickly, so direct access to video RAM is more appropriate than making a BIOS call ...
Like DOS-RMX, this system provides a hybrid mixture of services and capabilities defined by DOS, Windows, and iRMX. Inter-application communication via an enhanced Windows DDE capability allows RMX tasks to communicate with Windows processes. [3] iRMX for Windows was originally intended for use in combination with the 16-bit version of Windows.
