Révolution 909 Upgrade for the Roland TR-909



This one is in via Michael Geyre.

Details via Addictive Instruments:

"Memory and display upgrade including the new firmware version you've been waiting 40 years for!

Like you, we worship this machine and we have put all our passion and know-how into this project." Principle:
The Revolution 909 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.
v5 main features:
Fixed Sync bugs.
32 Internal Banks.
Optimised and more instinctive workflow.
Mute function.
Full External Instruments Mapping.
Firmware Update via MIDI.
etc...
Select the v5 Firmware tab for more details about the new features.

The new labels for front panel(non permanent sticker).

  1. Pushing those typical machined pins that are used on all upgrade boards damages the ic sockets in your vintage
    instrument,those pins used are not made to be pushed into ic sockets,they are intended to be used with headers.

    The WILL damage your instrument,the pins are to thick and will damage the spring action of the sockets,then heating and cooling of the device may lead to bad contacts,you can't fix that anymore.
    idem with Gligli mods etc..

    1. 1- If you have sockets in your 909, they were added, not supposed to be here.
      2- The small Digit Board is installed with lead-frames, so no problem with sockets. It's made for that!
      3- The Memory board have 0.41mm diameter(round) pins and is intended to be used directly or with matched low profile sockets.
      Don't be so sure of yourself, so assertive. Unless you have an oversized ego, tell yourself that if you have thought about these issues, others may have done so too.
