New Features for ADB-USB Wombat

New firmware 0.3.5 is now available for the ADB-USB Wombat! The Wombat is a bidirectional ADB-to-USB and USB-to-ADB converter for keyboards and mice. Connect modern USB keyboards and mice to a classic ADB-based Macintosh, Apple IIgs, or NeXT, or connect legacy ADB input hardware to a USB-based computer running Windows, OSX, or Linux.

Firmware version 0.3.5 adds some new items to the feature list:

  • Support for remapping the Power Key for ADB-to-USB mode. This was a frequently requested feature from people using an old Apple Extended Keyboard with a modern PC or Mac. The default is unmapped, but you can use the Custom Keymap Tool to map it to a function key or anything else.
  • Separate keycodes for left and right side Shift, Control, and Option keys. Now if you wish, you can configure the left modifier keys to have different behavior than the right modifiers. I’d thought this was already happening before, but some extra keyboard magic was needed to make it work. The Apple Extended Keyboard II supports separate left/right side modifiers, but the AEK I doesn’t. If you’ve got an Appledesign keyboard or other model, let me know how it behaves.
  • Option to disable mouse-wheel arrow keys. When using a USB mouse on an ADB computer, there’s no equivalent of the mouse wheel. The Wombat converts mouse wheel rotations into keypresses of the up/down arrow key, which accomplishes a similar result in most software. If it causes problems, this arrow keys behavior can now be disabled using the Custom Keymap Tool.

You’ll find firmware 0.3.5 in the Downloads section of the Wombat page. And if you don’t have a Wombat yet, they are available and shipping now.

    I’ve installed the 0.3.5 firmware (it went very smoothly on both my Wombats) and have a question about remapping the power key. What does 0x66 (Power) do if I assign that value to the Power key when using an old ADB Apple Extended II keyboard with a modern Mac mini?

    I think most people were looking to map the ADB power key as an extra function key or macro key of some type. I’m not sure what USB keycode 0x66 does on a Mac Mini. It won’t turn on the computer or wake it from sleep. Best case, it might let you put the computer to sleep, or reboot it if combined with Command and Control.
