Kawai Synthesizers

I'll bet these cards are very hard to come by nowadays. I need to 
know if anyone has any of these they will part with. I'm going to 
attempt to test the newer cards which start at 64K. They should only 
access the first 16k from the synth since added address lines in the 
card access the next higher ram locations. What would be neat would 
be to add switching that could get to each bank of 16K. So each card 
could hold a multiple of 16 up to its full capacity. Are these cards 
68pin PCMCIA based? So many questions so little time... Thanks,
