Your z3660 gives you a fast Amiga, optionally with network, audio and graphics expansions. Please do share what you use yours for on the Discord server!

You are strongly recommended to keep your z3660 up to date, with the best source of information on updates being the Discord server.

• zTop for the ARM core, requires HDMI connection
• gives access to all settings, including a new MAC address setting
• change kickstarts, options, CPU etc...
• Saves edits in ENV directory, overriding settings in z3660_cfg.txt

• zTop provides a way to diagnose and configure your z3660 via the Amiga GUI. It has a tabbed interface.
• Settings made in z3660 are saved in the ENV directory of your SD card, and thus override any settings in the z3660cfg.txt file on your SD card

• 1.03 beta 4 and earlier: There is currently just one ENV variable used by the Network driver: Z3660_MAC(1).
• 1.03 beta 5 and later: The MAC address can be initialized in the z3660_cfg.txt file(2).

(1)Z3660_MAC should contain 16 characters that form the MAC address for the zTurn network to use

(2)MAC address in z3660cfg.txt file is defined as also 16 characters, but in six groups of two hexadecimal digits, separated by colons ':'

• 1.03 beta 11 and later: the configuration of the z3660 was based on the z3660cdf.txt and some env files on SD.
  Those env files will be automatically deleted with 1.03 beta 11 and later. With the ARM's ZTop app ('Z' after power on your Amiga), you can set up to 8 different presets. Every preset will store all config parameters, so it will be easy to change between different configurations.
