I did some development on uVAX in 1989. Wrote a DECWindows app that did monitor & control of a distributed realtime system. DECWindows was slow, so it would get updated every 250ms, while the realtime stuff communicated to a proxy (via 10Mbps DECNet with a custom driver) every 20ms. All of the code was in 'C', but everything aside from the DECWindows stuff was running from ROM on embedded VAXELN.
