Call for Keyboards

The RetroMax (and for the Color Maximite 2 that the RM is based upon) uses a USB keyboard connection that should work with many USB keyboards. What I’d like to do in this post is to ask you for the make and model for any keyboard that you use that works with the RetroMax. And any that don’t…

There have been issues with some keyboards. Often this is solvable with a better power source. Some keyboards draw a lot of current and the RetroMax would need to be powered from a reliable power source through a quality USB cable.

The RetroMax will accept a standard USB keyboard including most that have a wireless dongle for the USB connection. Note that you cannot use a USB hub on this port or keyboards that have a built-in hub.

When the keyboard is connected or on startup the RetroMax will enumerate the keyboard and if this is successful the SD card activity LED will be solidly illuminated. On the first access of the SD card the LED will revert to its normal action (illuminated during SD card access).

Below is a list of keyboards that work as well as some makes and models that have issues.

  1. Keyboards with issue: rapoo model E9110 Wireless Ultra-slim Keyboard
    (not recognized by CMM2)

  2. Amazon’s (B003NREDC8) “Logitech Desktop MK120 Durable, Comfortable, USB Mouse and Keyboard Combo” seems to be working for me.
