Icon system advice wanted

[David L. Smith]

My company is considering the purchase of an Icon MPS020 system.  Is anyone
out there using this system?  I'd like to know how good their 4.2 BSD 
implementation is, if the machine lives up to its performance claims, and
what kind of service I can expect.  We have a very single-character i/o 
intensive application and I'd like to know if their i/o processors really
help out here.

Any advice, recommendations or flames on the machine would be most appreciated.

		Thanks in advance
