This was an eye opener for me.
I always thought this sounded dull and strange in the shops.
Then I got one to my home and I got to spend hours on it.
It truly is a masterpiece of a synth.
It was in working order but had intermitent chrashes.
So I got a new power supply from synthronics.de and put coolers on those
CEM5530 chips and it now works perfect.
