Squeak: Difference between revisions

Revision as of 13:01, 1 February 2015

Squeak is a multi platform open source Smalltalk environment originally released in 1996 by Apple. There exists a native, high performance Squeak port, written specifically for OS/2. It uses DIVE, the game oriented display API from IBM, that uses hardware acceleration to achieve fast display updates. The result is a quite fast Squeak even on a 486 machine.

It includes a convenient mapping of several keys in the VM. Ctrl-Break and Esc are the interrupt keys and, Ctrl-Ins, Shft-Ins and Shft-Del manage the clipboard (emulating Alt-c, Alt-v and Alt-x). Besides all Squeak color depth are supported from 1 to 32 bit. If you select a Squeak color mode with more colors that your OS/2 desktop, color dithering will occur, giving a very good illusion of having more colors than you really have.

This version has support for sound and TCP/IP networking. It doesn't still have support for MIDI, serial port or joystick.

System requirements

Long file name support (install Squeak on a HPFS or network drive)
DIVE video dlls (Installed by default by OS/2 Warp 4 Multimedia Support, but can be added to any OS/2)
DART audio dlls (Installed when installing an audio card, but can be added even without one)
Video mode with at least 256 colors, and support for DIVE (any driver should work)

Version

Latest Version: 3.5 (2003/06/05) Hobbes
Last known DOS version: 2.0 (Squeak 2.1)
