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. This is where the 8kb limit comes from
*Later models of calculators are missing RAM pages
*Later models of calculators have a longer LCD delay

 *Equality tests (2nd->TEST) will not work with complex numbers, despite what the manual says.
 *TIOS sets the RAM Execution Limits so that if PC is greater than or equal to $C000, provided an even-numbered RAM page is swapped in the upper bank, the calculator will crash.  On a TI-83+ SE, TI-84+, and TI-84+ SE, this can be changed via ports [[83Plus:Ports:25|25]] and [[83Plus:Ports:26|26]].  On the TI-83+, this is controlled with ports [[83Plus:Ports:05|05]] and [[83Plus:Ports:16|16]].

+*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 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.
