Ever see one of these?

No not the 59 Chevy 2dr Hardtop, notice that extra long master cylinder with what appears to be 3 ports and reservoirs.

There was a write up on this a few months ago, I think in Street Rodder.  The third port is hooked to a pressure accumulator and it replaces the power booster.  It basically is a version of power brakes that works like the truck brakes that run off the power steering pump, except it is pretty much self contained.  I think we talked about it a while back also, I was wondering what they based it on.  Check the archives
