- There was a good talk/paper at OOPSLA last fall about a realtime telecom
- switch system build in Smalltalk on top of the psos+ realtime os. The
- speaker said that it was by far his most productive project yet with the
- lowest level of defects (his early designs had been done in C and C++). It
- was a VME based system running on something like up to 100 68040 based
- switch cards. And yes they did have to spend some time timing the code and
- being careful of what they did but it sounded like a resonable amount of
- effort given the result.

- The paper is "Implementing a Real-Time, Embedded, Telecommunication
- Swithcing System in Smalltalk" John Radford.
