This program turns an ordinary TI-86 calculator into a shutter release trigger for some Canon (and possibly many other) cameras using nothing more than a data-link cable. Future versions will include self-timer, interval, and long exposure modes.
We are going to make a multipurpose librairy for the Texas instrument 68k calculator (TI-89 & TI-92+)
We are planning to add optimized graphic routine, and a lot more...
Grayscale graphic will be added too, of course :)
