Roland System 100m

I got a Roland System 100M in trade some months ago, and just back from the repair shop 
to vet it, put in a US power supply as recommended by people in this group, etc. ( BTW, my 
local tech found his initials inside -- he had repaired it at Roland Japan in 1984 -- he was 
in their repair department then/there -- amazing!).

In any case, I set it next to my Blacet modular, a handsome pair --

And of course, within short order I was cross-patching, running the VCO from the Blacet 
into the 100M's filters, etc --

Has anyone had any experience cross-pollinating these two machines?  I assume they use 
the same voltage(s) -- so all is OK on that scale, right?

Any other hints, cautions, wisdoms, exciting tales from the front?
