About a couple of years ago we were able to run DECnet Phase IV on Ethernet, by running TOPS-10 7.04 on the KLH10 emulator. Alas, to idle the emulator, the TOPS-10 monitor has to be modified so that it would make some I/O to a special device which would trigger the idle code into the emulator, but we never figured out how to do that. The TWONKY image has 4 different TOPS-10 7.04 monitors. http://klh10.trailing-edge.com/ One has LAT, and another has LAT and DECnet. Having LAT is nice if you have a LAT terminal server, since it allows you to easily connect a real terminal. :-) I'm afraid I can't help on the throttling. Zane -- | Zane H.
