Mapar007: clarified the stuff about $C000

{{stub}}

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
*Later models of calculators are missing RAM pages
*Later models of calculators have a longer LCD delay

83Plus:OS:OS 2.53MP Changes

2010-02-09T14:43:07Z

Mapar007:

IMPORTANT NOTE: The 2.53MP is a leaked beta. Please do not distribute it to people by calculator until TI makes the official release, slated for February 15. Use at your own risk.

I have recently realized that there is already an OS versions page. The two will be merged when the official release is made.

= Added Features =
* In MP, press up to scroll through previous entries, which allows basic copy and paste.

== New Tokens ==
* AUTO Answer -- basic
* CLASSIC -- basic
* DEC Answer -- basic
* >F<>D -- swap between fraction and decimal
* FRAC Answer -- basic
* logBASE( -- log to any base, logBASE(x,base
* MATHPRINT -- basic
* n/d - normal fraction, numerator n/d denominator
* >n/d<>Un/D -- swap between improper and proper fractions in MP
* randIntNoRep( -- gives a list of random integers, with dimension high-low+1 randIntNoRep(low,high
* remainder( -- essentially modulo, x % y, remainder(x,y
* summation <sigma>( -- <sigma>(expression,variable,start,end
* Un/d -- mixed number, whole Un/d numerator n/d denominator
* ZFrac1/2, EF18 -- delta-x,y = 1/2, graph centered
* ZFrac1/3, EF19 -- delta-x,y = 1/3, graph centered
* ZFrac1/4, EF1A -- delta-x,y = 1/4, graph centered
* ZFrac1/5, EF1B -- delta-x,y = 1/5, graph centered
* ZFrac1/8, EF1C -- delta-x,y = 1/8, graph centered
* ZFrac1/10, EF1D -- delta-x,y = 1/10, graph centered
* ZQuadrant1, EF17
* fraction related tokens
** _, EF2F, not the same as printing _. New font codepoint 0F5h.
** /, EF2E, not the same as division /. New font codepoint 0F6h.
** box, EF1E. New font codepoint 0F7h.

== New Functionality ==
* New ZOptions under Zoom
* Math Print is TI's own pretty printing
* New menu Alpha+F1-F4 for use with Math Print

== Flags ==
* 5, (iy+44h) controls math print. You should clear the screen if you change this flag.
* 0, (iy+48h) controls the fraction mode
* bits 1 and 4 of (iy+47h) are related to when the OS decides to format an answer as a fraction
* 4, (iy+45h): set this to disable the message about shortcut menus from Press-to-Test. Not affected by Reset Defaults, though Math Print is.

= Compatibility Issues =
* Programs using the homescreen may be very broken. Users should disable Math Print before running them, and programs should clear the screen first thing.
* Programs that encounter an error on the graphscreen may end up with the graphscreen contents in the homescreen buffer
* In Omnicalc, parenthesis assistant does not work properly. (Display error)
* In Omnicalc's entries menu: Using the entries menu without MP symbols has some display issues, and when selecting an entry, it crashes.
* In Omnicalc's entries menu: With mathprint symbols in the entries log, there are serious display issues accompanied with a dramatic crash.
* Omnicalc's partial line clearing (always enabled) crashes or glitches when you try to use it in MP.
* Calcutil will not run at all correctly and will crash your calculator when you turn it off and back on.
* ld a,1 \ ld (appInfo+2),a \ bcall($50CB) no longer unlocks the flash ROM.
* MathPrint Bug : When a list is displayed as a result, you can't take it back for you new entry : selecting it and pressing enter doesn't work

= Known Performance Issues =
* Disp and Output may be up to 4x slower than on previous OS version when MathPrint is enabled (see [http://www.cemetech.net/forum/viewtopic.php?p=93740#93740 TI-84+ OS v2.53 Leaked])
* When MathPrint is enabled, when you go to the "Y=" menu to type a function, it's displaying slowly the Y1, Y2, Y3, Y4 etc.

Hi. I'm Mapar007. I'm from Mechelen, in the Flanders region of Belgium. I'm an z80 ASM programmer with, at the time of writing (Dec '09), about a year of experience; I haven't touched BASIC for an equal amount of time. Currently I'm doing a combination of Latin and Math at secondary school

[[Category:83Plus:BCALLs:By_Name:Other|GetRestrictionsOptions]] [[Category:83Plus:BCALLs:By_Name|GetRestrictionsOptions]] [[Category:83Plus:BCALLs:By_Address|531D - GetRestrictionsOptions]]
== Synopsis ==
'''Unofficial Name:''' GetRestrictionsOptions

'''BCALL Address:''' 531D

'''Minimum OS Version:''' 2.40

Displays configuration screen for Press-to-Test and returns the user's choice.

=== Inputs ===
* Carry flag: set for delete menu, reset for disable menu

=== Outputs ===
* Z set if user canceled with [2nd]+[QUIT]/[CLEAR]/etc., reset if OK selected
* B: bit 0 reset for radians, set for degrees
* B: bit 1 reset for stat diagnostics OFF, set for ON

=== Destroys ===
* All
* ([[83Plus:RAM:8478|curRow]]): 0

== Comments ==
This clears the screen, sets up the homescreen context, and empties the edit buffer.

This is only intended to be used with applications, not RAM programs. It is also the only BCALL to use the carry flag as input.

It also kills all hooks.
