This is a native, high performance Squeak port, wrote especifically 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 in slower machines.
Highlights
o Integrated into VMMaker!
o All Squeak display depths supported (1, 2, 4, 8, 16 and 32 bit) on any video card mode
o Dithering when using more colors than the current video card mode
o Full duplex sound
o TCP/IP
o Midi
o Convenience keys emulation
o 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).
