Hi, Does someone know what's the standard clock tick delay programmers are using between two OUT's to the LCD? First, my TI-83 needed 41 clockticks, but nowim using other batts (rechargeable) and now I need about 50 ticks. What's the maximum of ticks a TI-83 should need? I need it for my graphmem2screen routine. It works fine now on my calc, but I don't know if it'll work on others. Bye Cheiz
