Description
Squeak is a multi platform open source Smalltalk environment originally released in 1996 by Apple.
This is a native, high performance Squeak port, wrote specifically for OS/2. It uses DIVE, a 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)

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