- 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 CXY08 is an S-box version of the DHQ11. Functionality should be iden-
- tical.

- Bleh! DL11's have no silos and are interrupt-per-character. 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.
