Atkinsonpoint: LISA Slide Show 1.1

Atkinsonpoint: LISA Slide Show 1.1, released 1 September 2026. This page was added on 9 November 2026 so the floppies have download links; nothing in the release has changed.

A native slide show tool for the Apple Lisa Office System. It shows 680 x 300 one-bit pictures, photographs dithered on a modern computer with the algorithm of Bill Atkinson. Click or press a key to advance, or let it run by itself at one of three speeds. Tool 419307, Lisa Pascal, Lisa Office System 3.1.

New in 1.1

• Copy Pictures from Floppy (Show menu): every .PIX file on a floppy is copied to the volume the tool lives on. The Workshop is no longer needed to install pictures.
• Remove This Picture (Show menu): deletes the slide on screen, in two steps.
• Bonus picture packs as floppy images.

Verified on a Lisa 2/10 (internal and external ProFile) and a LisaFPGA.
