Roland PR-100 Digital Sequencer. It is in fantastic condition, both cosmetically and internally and I have recently fitted a new disk drive belt so it should be good for many years yet.. 

This is a lovely piece of retro kit with everything working as it should.

Comes complete with a double sided Quick Disk for recording and playing back sequences. 

No PSU included. It uses a centre negative 9v PSU which are widely available for a few £s on eBay and elsewhere.

Will be well packaged and sent as soon as payment received.
