Sony DMX-R100

Hi y’all,

Maybe an unwise move, but I may get an opportunity to buy a Sony DMX-R100 console.
From what I understood, it has been tested and working.
Now anyone on this forum own one and what’s the word on the performance,
EQ, Dynamics and automation?
Is it possible to install plugins or DSP cards to add more or better ones to the stock ones.

Or do you think it’s a waste, that I should stay away from it and go another route.
Inputs will be appreciated.

Thanx in advance.
