Conquest was acquired by Garaventa in 2008, this is how they got into the residential elevator market. I'm sure they supported the product until old stock was used up. This is pretty standard when elevator businesses get bought. Having worked for Garaventa at the start of my career I always found it funny when home owners feel like they got the short end of the stick. Would you spend 40k on a car and never change the oil or brakes or tires? Probably not. Yet when it comes to their elevator it should just work all the time with no maintenance. Anyway, I'm sure you will be able to find someone in your area that has experience with these units. As far as boards go I'm sure they can be repaired at places like World Electronics, etc. Garaventa for whatever ever reason didn't keep the traction elevators, I seem to remember Thyssen ended up "stealing" it somehow and then shutdown their residential line some years ago. I could be remembering wrong though.
