NEWKEY/80 Lite
Keyboard Adapter for TRS80 Model 3/4


NEWKEY/80 - Possible Bad power cable? Important!

I have had a report that one of the NEWKEY/80 4-wire power splitters from my supplier had the yellow (+12v) and red (+5v) wires reversed. I believe this to be a unique occurrence but to be safe please read the following notice.

Why NEWKEY/80 Lite?
  • Replace your broken or poorly functioning TRS-80 keyboard
  • More familiar PC keyboard layout
  • Use your favorite wired USB keyboard on your TRS-80

  • Wired USB keyboard interface
  • Compatible with TRS80 Model 3 and Model 4 (Model 4P not currently supported)
  • Can work simultaneously with existing keyboard, if desired (when using the included deluxe ribbon cable)
  • Compact size. Mounts inside TRS80 case
  • Compatible with most standard wired USB PC keyboards
  • Fast and accurate key response
  • Native TRS-80 key repeat
  • Handles special keys independently (arrows, space, control, break, shift, @) for excellent compatibility
  • Works great with games and applications
  • Supports TRS80 Control key sequences (Shift+Down for control code input)
  • Upgradable firmware to allow for enhancements and bug fixes

  • NEWKEY/80 mounts inside the TRS80 case. This is a fairly easy process but does require +5v and ground connections. Recommend method is to tap in to existing TRS80 power supply. A 4-pin Molex Disk Drive power Y-adapter cable and a plain 2-wire power connector are included.
  • The NEWKEY/80 keyboard port is located on the adapter and is therefore located inside the TRS80 case.
  • A USB extension cable (not included) can be used to route the keyboard connector outside of the TRS80 case.
  • Wireless keyboards are not currently supported
