They are and they do; the hardware (as I understand it) contains a custom ASIC for the networking side, and a control processor implemented on an FPGA that runs the modified TOPS-20 monitor that Rich described. I was hoping there was sufficient product differentiation that they would (or could be persuaded to) release just the monitor component, but alas: that appears to be unlikely. - Dan C.
