The Kiwi-106 Upgrade Hardware

Upgrading to Kiwi-106 is a straightforward procedure, but you should download and run the Vyzex Kiwi-106 editor to convert and store your original Juno-106 patches first! Check out for details.

1. Head over the to order yours - There were 40,000 Juno-106 units sold back in the day, and there are many thousands that are still in service. Make yours a 21st Century synth!

2. When your Kiwi-106 upgrade arrives check to see if you know how to use a soldering iron and a vacuum de-soldering tool.

3. If you have the expertise and tools, it's time to party. Otherwise, find a reputable person who does have these essentials to act on your behalf. Check out http://kiwi-106/installers for our recommended service specialists.

4. Open the Juno-106 lid and remove the socket-mounted wiring connectors from the Main CPU board.

5. Unscrew the CPU board's brass mounting screws and set the board aside for later.

6. Transfer the brass screws from the original CPU board to the Kiwi-106 CPU board and thread them into the Kiwi-106 CPU board's included plastic stand-offs. You can now mount the Kiwi-106 CPU board in the footprint of the original CPU and reconnect the wiring harnesses - All the sockets will line up.

7. Remove the socket-mounted wiring connectors from the Juno-106 Voice board. Unscrew the Voice board's brass mounting screws and take the board over to your work bench.

8. Using a vacuum de-soldering tool, remove the voice assigner chip (See the Kiwi-106 User's Manual for details). Set it aside for now.

9. Install the milled sockets into the voice assigner chip's now-empty mounting holes. Carefully install the Kiwi-106 Voice Daughter Board into the socket.

10. Re-install the Juno-106 Voice board into the instrument and reconnect the original wiring harnesses.

11. Install the Kiwi-106 CPU Bridge Ribbon Connector between the Voice Daughter board and the Kiwi-106 CPU Board.

12. There is an optional modification you can make to the back of a panel board that involves wiring a link between two points (to short out a current limiting resistor) on the back of the front-panel board. this will increase the brightness of your SAVE/VERIFY/LOAD panel LEDs to deal with the increased work Kiwi-106 will have them do.

13. Close the lid and fire up your newly upgraded Kiwi-106!

14. Choose where you want to mount the metal Kiwi-106 logo plate: We recommend the lower right corner of the front rail of the unit, just under the keybed: That location is where the SCI Prophets had their nameplate and it has a nice 'vintage polysynth' vibe to it. See for more details.
