i think the OB-Mx got a bad rep as an unfinished product that didn't really work so demand for them and prices were low.

actual owners knew better though and rushed to complete their systems. demand for cards got to a point where it was much better to part out individual cards rather than sell an OB-Mx loaded. now voice cards are extremely rare.

about four years ago, i found a person in L.A. in this situation and was going to get a card from him to finish off my second OB-Mx but to my regret, i was traveling in and out of the city too much to make it happen.

Even with the limitations this slightly wobbly card imposes it's still my favourite machine and may be the cause of my general dislike of the digital perfection of analogue modelling and plug-ins. I noticed a couple of years back someone got over £500 on eBay for a voice card and for a few months they were changing hands more regularly than I have seen before or since but at prices that were out of reach for me (in fact the were selling for twice what I paid for the whole synth).
