LSWVST Smalltalk-OS

LSW Smalltalk OS ( LSWVST-OS ) is an Operating-System which consists of a compact Runtime-System which is about 50.000 lines of Assembly-Macro-Language 60.000 Smalltalk-Methods. Also Microsoft Research is working on a new Operating-System - written Singularity entirely in C#.

Features of LSWVST-OS :

•     Slim OS-Micro-Core written in Assembler ( Booting + Bootstrapping  )
•     Flat-Memory Model
•     Real-time OS
•     Smalltalk-Runtime with adaptive compilation to Machine-Code
•     Device-Drivers all in Smalltalk
•     Windows GUI with controls like TreeView, ListView etc.
•     Kernel can be debugged with Smalltalk-Debugger

Advantages

•     Superfast because we eliminated a lot of OS-Layers
•     We never have to reboot if we change the OS

LSWVST-OS was done on Winter 2004 - now we are heavily busy with our LSW DotNet-Lab and we plan to resume it in Winter 2007
