REVOLUTION 909 V5 FIRMWARE INSTALL SERVICE

REVOLUTION 909 V5 FIRMWARE  INSTALLATION  SERVICE 

The Revolution 909 B upgrade consists of two hardware modules which replace some integrated circuits on the 909’s Switch Board.
The first is a hardware memory expansion module including a new version 5 of the software.
The second is a small hardware enhancement to the 7-segment LED driver to display alphanumeric characters.

The new v5 firmware not only contains fixes and optimizations of the original versions 1 and 4, but new features have also been added!
The functionality and timing of the original sequencer has been preserved.
The spirit and philosophy of the machine has been respected. Remember, we always run on the same CPU

Legacy versions 1 and 4 are also present in ROM and can be selected by a simple key combination.

This upgrade is fully compatible with the TR-909, the RE-909 and the SR-909.

The installation is totally non-destructive, no holes to drill, no traces to cut.
