I don’t have a micro system. That’s never going to happen, especially not in a fetish sort of way But, of course, I can designate any set of modules as a “micro system”. Whatever
The only reason I’m saying anything here is that I just paid for an ADDAC506 (and a 21U monster frame). Also, I have 3 Maths, and they’re not going anywhere, for the simple reason that Maths is brilliant and not replaceable with the 506. After reading the 506 literature, I concluded that they are functionally different.
