OBERHEIM SYNTH

Or a good forum to talk about them? Sorry to ask here in the Oberheim but I really love this group. I just picked up 2 Linn 9000s today off Craigslist. I am pretty stoked about one of them as it was modded up by Forat in the 90s. The other is just a stock unit. Unfortunately the Forat modded one is missing the Tom Toms and Conga cards but it has the A/D converters and SMPTE cards. I have only tried turning the Forat one on after the PSU checked out and all I got was the screen coming on giving me blocks across the top and the record and play button lights coming on. Don't really know where to start on these guys! I just posted an album if you want to see pictures.
