Stovepipe system

In engineering and computing, a stovepipe system is a legacy system which cannot be upgraded or refactored and which must be built around until it can be replaced entirely.

Examples of stovepipe systems:

Systems for which new hardware is no longer available.
Systems whose original source code has been lost.
Systems that were built using old or ad hoc engineering methodologies for which support can no longer be found.

A stovepipe system is an example of an anti-pattern.
