One stack architecture that is alive and doing well is the entire
Unisys Clearpath NX server line. These implementation is based on an
specification known as e-mode the latest that being e-mode Delta.
This architecture was developed to support ALGOL and its
extensions. Those in the know will be struck by the similarities
between the JVM and E-mode. If implemented right the JVM on NX
servers could be tremendously fast.

architecture is close to 40 years old, it's pretty decent. -John]
