Turbo BASIC XL memory map?

[tschak909]

#atari8bit #FujiNet Does anyone have a definitive memory map of Turbo BASIC XL? My N: Handler seems to be conflicting with Turbo BASIC XL under some DOSes, and I need to see if I can improve this.

See the code at https://github.com/dmsc/turbo-dis/blob/master/turbo-mads.asm

 

Basically, you have the loader first (not used after load is finished):

- Loader font: $5C00 to $5FFF

- Splash screen code: $2100 to $2193

- RAM under ROM Loader: $6000 to $617F

 

And the code:

- Low code:    $2080 to $3628

- Interpreter stack: $2100 to $21FF

- FP temporaries: $22CA to $22FF

- High code 1: $C000 to $CBF5

- High code 2: $D800 to $DFF9

- High code 3: $E400 to $FFFF

 

As always, the interpreter uses memory from $3629 upwards to store the BASIC program, and $580 as the input buffer.

 

Have Fun!

This is all I have

Perhaps MEMLO + N-Handler > $2080

life sucks.

 

I really need someone to write a better N: handler.

Basically, for now, anyone who wants to write N: stuff in Turbo BASIC needs to use @dmsc's special version of Turbo BASIC, which relocates itself.

Hi good afternoon.
how can you switch off the basic rom with it?
other program can use the memory?

thank you.
