I've added "Chasm" to the Dropbox folder. Decelerator is a utility to slow the machine down and Sponge generates 3D fractal sponge graphics, so I haven't scanned those.
Edit: June 1987's "Solitaire" is a program which lets you set up a solitaire board (the game with a round board containing a grid of pegs, I think - not the card-based "patience" solitaire) and will solve it automatically. This probably doesn't count as a game, but I can scan it if you're interested.
