  • 26 June 2019 - new batch of ARMSIDs in stock again

    Due to high demand we produced a new batch of ARMSIDs. All ARMSIDs in the stock have the newest firmware v2.9.
  • 9 June 2019 - new ARM2SID firmware 3.6

    A quick response in stereo mode was added (when using the second socket), the dual-mono mode is activated without timeout when both sockets are addressed at the same time.
    The new firmware is easy to update directly in your C64 or C128 computer. You can download it and get more info at http://dzi.n.cz/8bit/arm2sid/index_en.php
  • 29 May 2019 - new ARM2SID finally in stock

    After some firmware polishing we have finally ARM2SID in stock and available for purchase. Sorry for the delay.
  • 18 April 2019 - new updated e-shop

    • new updated design
    • more products
    • VAT exemption for export to countries outside European Union
    • VAT reverse charge applied for EU customers (companies) with valid EU VAT Id
  • 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.

  • 14 April 2019 - ARMSID out of stock

  • 1 March 2019 – postage pricing updated

    New better postage pricing! 1-3 ARMSIDs for the same postage & packaging price!

  • 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.
