Using AnalytiCalc on Amiga: 1. Be SURE your workbench is in INTERLACE mode. Select Interlace in Preferences, SAVE, and then REBOOT, if you do not have an interlace (640 by 400 or larger) workbench screen. AnalytiCalc MUST be run on a system with a workbench screen of 640 by 400 or larger (i.e., using MOREROWS is perfectly OK) or it will fail. 2. No extra stack should be needed, at least most of the time. 3. AnalytiCalc has been reported to be runnable in a 512K Amiga, but with VERY little room left over. Any extras that occupy memory may make it not fit (e.g., ADDBUFFERS...)
