Roland CR-78 CompuRhythm Drum Machine

via this auction
"* Sync the CR-78 to any other Din Sync device
* Select the playback sync rate to: (1) normal speed, (2) double speed, (3) half speed
* Use external positive polarity Gate or Trigger signals to program patterns into the CR-78 user memory.
* Manually tap a beat into the CR-78 user memory using the momentary switch on the front panel.
* Front panel blue LED lights to show when external gate or trigger signals are being received.

The unit has been recently serviced, the battery has been professionally replaced so no risk of leakage and the NMOS RAM chips have been replaced. The Roland service manual is included.
Programming from one of these devices is simple. By syncing the playback of the CR-78 to your Din Sync master, you can then send the programmable trigger or gate signals out of the master into the programmer interface and on to the CR-78 for storing your own custom rhythms in the CR-78. When using a Din Sync master device which also has MIDI such as the Revolution, you can then sync your CR-78 to any other MIDI sequencers as well "
