boils down to a 87x87 matrix. This is due to a total of 6 opamps which
all are submodels and thus add their own internal nets.
Gauss Seidel iterative solving comes to it's limits.
nltool runs this at about 50% speed on my machine. Given the complexity
this is quite good. Yet, any m62 game currently will not be playable.
Time for a new cpu :-)
