Chac 2.1

Chac is a meso american calendar for the Macintosh. You may have seen the original version of this program called Mac Maya. This is a complete rewrite of that program. The author threw away most of the source code and started over. The goal was to write structured code, a more powerful program with all of the features a serious researcher would want, a better user interface and better graphics. In other words, a more powerful and cooler program. This is a fat binary and runs on 68k and PPC Macs. You need System 7 or greater. It needs 348k of RAM but 1 megabyte is recommended.
