I currently have an OSCar for sale. This is a late production version with the most extensive Midi spec. It is in excellent condition and fully working. As far as I'm aware it has never been gigged. It comes with the original manual and its original accompanying data cassette tape which supposedly contains the factory patches (although I have not tried loading the data from it).
I'm in no rush to sell so am looking for a good price. I'm in the UK and would prefer to sell to a buyer who can collect as I am reluctant to ship something like this. I may be able to deliver within certain areas (eg. the west country, south Wales).
Contact me via the feedback page if interested
