    en.wikipedia.org/wiki/Intel_8085

    The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.

    en.wikipedia.org/wiki/Simple-As-Possible_computer

    The instruction set architecture (ISA) that the computer final version (SAP-3) is designed to implement is patterned after and upward compatible with the ISA of the Intel 8080/8085 microprocessor family. Therefore, the instructions implemented in the three SAP computer variations are, in each case, a subset of the 8080/8085 instructions. [2]

    en.wikipedia.org/wiki/Intel_8086

    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 ...

    ISIS-II has been distributed as part of the Intel Microprocessor Development System and includes standard operating system commands (COPY, DELETE, DIR, RENAME, FORMAT) [3] and debugging software (assembler, linker and debugger for external debugging in the developed device). There are two editors, one of which, AEDIT, contains editing macros ...

    en.wikipedia.org/wiki/Block_diagram

    A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .

    en.wikipedia.org/wiki/KR580VM80A

    The KR580VM80A (Russian: КР580ВМ80А) is a Soviet microprocessor, a clone of the Intel 8080 CPU. [1] [2] Different versions of this CPU were manufactured beginning in the late 1970s, the earliest known use being in the SM1800 computer in 1979.

  9. Intel 8259 - Wikipedia

    en.wikipedia.org/wiki/Intel_8259

    The 8259 may be configured to work with an 8080/8085 or an 8086/8088. On the 8086/8088, the interrupt controller will provide an interrupt number on the data bus when an interrupt occurs. The interrupt cycle of the 8080/8085 will issue three bytes on the data bus (corresponding to a CALL instruction in the 8080/8085 instruction set).
