One of my UUCP leaf sites has an MVII with a DHV11. That system is pretty busy, yet they average 1350+ CPS using DECUS UUCP. > The top speed of the DHV/DHQ/DZQ appears to be 19.2; the only board > that's 38.4 capable for the Qbus is the CXY08, and it looks like this > board isn't supported on the MVII. The CXY08 is an S-box version of the DHQ11. Functionality should be iden- tical. > Any suggestions?

If you're going to go through the trouble of doing a driver, either get a KXT11/KXJ11 and do it on a coprocessor or buy a complete kit from Simpact. If you want a more "stock" solution, get an Ethernet board (if you don't already have one) and a DECserver 700.
