Lisa Reversi 1.0 (REV D), released September 2026. This page was added on 9 November 2026 so the floppy has a download link; nothing in the release has changed.
Reversi for the Apple Lisa Office System: an 8 x 8 board drawn with QuickDraw, you against the Lisa, four playing levels, legal-move dots, unlimited undo, and an exact endgame at the two harder levels. Tool 419309, Lisa Pascal, Lisa Office System 3.1.
Proven on real hardware: REV C passed the full test list on the LisaFPGA and a Lisa 2/10; REV D adds the missing cutoff in the last ply of the search (the same moves for a third of the work).
File: LISA_REVERSI_1_0.dc42, a 400K Disk Copy 4.2 floppy. Drag or duplicate Lisa Reversi onto your hard disk.
