ROM workstation synths with 61 and 76 keys respectively. Great sounding machines using common cards for JV1080 etc.
Not aware of any issues on these, save that if outputs fail someone may have hot railed the jacks in which case you'll find a burned smt coil between jacks sometimes I believe. Your output will just buzz because the coil opens and no more ground :-)
Roland may still have some parts for these. And also there are some discrete components that I usually stock.
