Other than a few resistor values changes on the M boards, there are the
same. The SH and KAS boards will be missing half their parts (4vc vs.
8vc) on the CS-50, but those parts can be installed easily enough. The
KAS board gets the number of notes to assign from pull-down resistors on
the K1~K8 pins. The CS-50 & 60 do not have things like the TKC/TKB
boards, of course.
I bought my CS-50 for the very reason you state: CS-80 spare parts.
But after fixing the damage inflicted on it by UPS, I decided it was
interesting enough to keep and let live its own life.
