HP Distributed Smalltalk

A version of Smalltalk created by the Hewlett-Packard in the early 90s, that featured a distributed CORBA based object system. Initial version ran on HP-UX and Microsoft Windows 3.x and featured a version of VisualWorks underneath, but after some input from IBM was ported to SOM and made available for AIX and OS/2 and versions were made available for Solaris and Windows NT as well. Code is fully abstracted from the host OS so an application written for one host OS will be portable to others without any code change.

HP sold the system to ParcPlace-Digitalk in March 1996.
