  2. Intel 8085 - Wikipedia

    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.

    The LXI standard does not define a mechanical format. LXI products can be modular, rack mounted, bench mounted or take any other physical form. LXI products may have no front panel or display, or they may include embedded displays and keyboards. Use of Ethernet allows instrument systems to be spread over large distances.

  5. Hitachi HD64180 - Wikipedia

    en.wikipedia.org/wiki/Hitachi_HD64180

    The HD64180 will not execute the "undocumented" Z80 instructions, particularly the ones that access the index registers IX and IY as 8-bit halves. The Hitachi CPU treats them as illegal instructions and accordingly executes the "illegal instruction trap" behavior of resetting the PC register to zero, which simulates a cold restart by ...

    The mnemonic letter M, for memory (referenced by HL), was lifted out from within the instruction mnemonic to become a syntactically freestanding operand, while registers and combinations of registers became very inconsistently denoted; either by abbreviated operands (MVI D, LXI H and so on), within the instruction mnemonic itself (LDA, LHLD and ...

    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.

  8. Illegal opcode - Wikipedia

    en.wikipedia.org/wiki/Illegal_opcode

    An illegal opcode, also called an unimplemented operation, [1] unintended opcode [2] or undocumented instruction, is an instruction to a CPU that is not mentioned in any official documentation released by the CPU's designer or manufacturer, which nevertheless has an effect.

    The SDK-85 MCS-85 System Design Kit was a single board microcomputer system kit using the Intel 8085 processor, clocked at 3 MHz with a 1.3 μs instruction cycle time. It contained all components required to complete construction of the kit, including LED display, keyboard, resistors, caps, crystal, and miscellaneous hardware.
