NEWKEY/80 -
Special order only

The microcontroller I use for these boards have had a +250% price increase. Because of this I will not be stocking any more DUO-JOY boards. If you really want one and are willing to pay the increased price please use the Contact page and we can work it out.

Please see my NEWKEY/80 "LITE" board as an alternative USB keyboard adapter (cost-reduced, but less features).

Why NEWKEY/80?
  • Replace your broken or poorly functioning TRS-80 keyboard
  • More familiar PC keyboard layout
  • Use your favorite USB or PS/2 keyboard on your TRS-80
  • Play games using an Atari Joystick!

Features:
  • USB and PS/2 keyboard interfaces (active port based on currently loaded firmware)
  • Atari 9-pin Joystick port
  • 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 PC keyboards
  • Works with wireless 2.4Ghz USB 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)
  • Easily upgradable firmware to allow for enhancements and bug fixes

Notes:
  • 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 keyboard extension cable (PS/2 or USB, not included) can be used to route the keyboard connector outside of the TRS80 case.
  • A common 9-pin serial or Atari joystick extension cable (not included) can be used in a similar fashion to route the joystick connector outside of the TRS80 case.
  • Wireless keyboards need to be the "no drivers required" type

Suggested Keyboard

I believe that I have found the perfect keyboard for use with NEWKEY/80. It's the Wireless USB Jelly Comb KS037 ($36 on amazon). It fits perfectly in the Model 3/4 case (once the old keyboard is unscrewed and removed).

I've also designed a small 3D-printed center post that provides a little more support and keeps the keyboard centered. Use by hot-gluing a small metal washer on the underside of the USB keyboard and place the 3D printed support post over the top of the existing TRS-80 keyboard support post.

This is my recommendation if you wish to replace your existing Model 3/4 keyboard.

Please note that NEWKEY/80 also supports using both the old and new keyboard at the same time if you do not wish to remove the old keyboard.
