Hardware Quirks
The TI-83+ family of calculators has some interesting quirks in the hardware.
- The calculator will crash if PC is greater than or equal to C000, provided an even-numbered RAM page is swapped in the upper bank. This is the default (page 80h). This is where the 8kb limit comes from. Seems like an imposed hardware constraint.
- Later models of calculators are missing RAM pages
- Later models of calculators have a longer LCD delay
- If a LD A,I or LD A,R instruction is interrupted, then the P/V flag is reset, even if interrupts were enabled beforehand.
TIOS Quirks
- In TI-BASIC interpreter an If inside a For( loop without ending parentheses can cause an abnormal time wasten in interpretation.
- There are lots of bugs specially in old buggy versions as this topic describes.
