A close up look at the TR-909

Here's a two part video showing many of the features of the TR-909, including some information on the various serial number revisions. How to copy and paste patterns and also how to use it as a midi sequencer to trigger an external midi instrument. The diode mentioned that should be replaced in early versions is D701 which should be changed to a 5.6v zenner for stable operation. More details of this can be found in the service notes
