Commodore Amiga 2000/3000/4000 I2C controller as Zorro-II card. This controller is software compatible to M. Boehmer’s ICY board. The main difference between the original ICY card and this design is that the PCF8584 I2C controller chip is mapped indirectly to the Amiga bus here. This way, occasional mis-configuration of the PCF8584 bus protocol and timing issues can be worked around.
The logic for the CPLD is based on the code for the A3000 daughterboard by Matthias Heinrichs, with some changes and additions to make it work on a separate Zorro card. The KiCAD footprint for the Zorro slot was imported from the VA2000 project by Lukas Hartmann.
While the main purpose of this board is to provide an I2C controller, there are some optional on-board extras.
- PWM fan controller that might be beneficial for finding a good balance between noise and cooling. This fan controller is compatible with the Fanny card and can be configured with the FannyCtl utility provided (manual for FannyCtl).
- Temperature/voltage monitor, based on the LTC2990. That monitor is configured in the same fashion as on the a1k.org ICYv2 card and Matze’s A3000DB and is supported out of the box by several utilities, e.g. simplesensors or Sensei.
Here you find some further useful information (link1, link2) from the a1k.org forum. Although the forum is in German, English speakers are very welcome. Further information can be found at the official project repository.
