  2. ROM image - Wikipedia

    en.wikipedia.org/wiki/ROM_image

    Intelligent Systems ROM burner for the Nintendo DS. A ROM image, or ROM file, is a computer file which contains a copy of the data from a read-only memory chip, often from a video game cartridge, or used to contain a computer's firmware, or from an arcade game's main board.

  3. Read-only memory - Wikipedia

    en.wikipedia.org/wiki/Read-only_memory

    For example, Atmel microcontrollers come in both EEPROM and mask ROM formats. The main advantage of mask ROM is its cost. Per bit, mask ROM was more compact than any other kind of semiconductor memory. Since the cost of an integrated circuit strongly depends on its size, mask ROM is significantly cheaper than any other kind of semiconductor memory.

  4. ROM hacking - Wikipedia

    en.wikipedia.org/wiki/ROM_hacking

    ROM hacking (short for Read-only memory hacking) is the process of modifying a ROM image or ROM file to alter the contents contained within, usually of a video game to alter the game's graphics, dialogue, levels, gameplay, and/or other elements.

  5. Color BASIC - Wikipedia

    en.wikipedia.org/wiki/Color_BASIC

    Color BASIC is the implementation of Microsoft BASIC that is included in the ROM of the Tandy/Radio Shack TRS-80 Color Computers manufactured between 1980 and 1991. BASIC (Beginner's All-purpose Symbolic Instruction Code) is a high level language with simple syntax that makes it easy to write simple programs.

  6. List of file formats - Wikipedia

    en.wikipedia.org/wiki/List_of_file_formats

    ROM, disk or tape images usually do not consist of one file or ROM, rather an entire file or ROM structure contained within one file on the backup medium.

  7. Diode matrix - Wikipedia

    en.wikipedia.org/wiki/Diode_matrix

    A diode matrix ROM was used in many computers in the 1960s and 70s, as well as electronic desk calculators and keyboard matrix circuits for computer terminals.A keyboard matrix circuit has a very similar grid of diodes, but is used differently.

  8. Option ROM - Wikipedia

    en.wikipedia.org/wiki/Option_ROM

    An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.

  9. Microcode - Wikipedia

    en.wikipedia.org/wiki/Microcode

    Microcode remained relatively rare in computer design as the cost of the ROM needed to store the code was not significantly different than using a custom control store. This changed through the early 1960s with the introduction of mass-produced core memory and core rope , which was far less expensive than dedicated logic based on diode arrays ...
