  • 16 April 2019 - new ARMSID firmware 2.9

    New features from the previous version 2.8:

    • Better compatibility with some older C64 models. A longer time is required to activate the reset signal.
    • Small fix in noise generator on the lowest bits. Also faster computing.
    • Other speed and code size optimizations.

    The new firmware is easy to update directly in your C64 or C128 computer. You can download it and get more info at dzi.n.cz/8bit/armsid/index_en.php.

  • 21 February 2019 - new ARMSID firmware 2.8

    New features from previous version:

    • The start and the end of the bus data cycle (reading or writing) is now controlled by signal CS only (it was the same on the beginning of the cycle, but the end was controlled by 02 clock before), it can help with a bus stability in other systems than C64 a C128.
    • Internal frequency generators are updated with precision of one 02 clock - about 1us (no audio signal phase changes after frequency retuning)!
    • Correct polarity of the bandpass filter.
    • Added emulation of internal filter voltage offset.
    • Added the "Digi Boost" feature by software - an effect similar to adding 330kOhm resistor between EXTin and GND on the MOS8580.
    • Other speed optimizations.

    The new firmware is easy to update directly in your C64 or C128 computer. You can download it and get more info here dzi.n.cz/8bit/armsid/index_en.php.
