Using $1D00 vs. $9D00 to document DOS3.3

[TommyGH]

I have an interesting idea for you to ponder. In your Github/Apple2_dos33 you are documenting DOS3.3 and its addressing based on a Master disk image and its initial load location ($1B00 relocator code and $1D00 for DOS proper) during the boot process. Almost everyone tracing DOS or looking at DOS using AppleWin (or other emulator) will almost always be looking at the $9D00 final resting place of DOS after the boot process is complete, especially since (I think?) most DOS3.3 disks are slave disks.

Have you thought about documenting Apple2_dos33 using the $9D00 addressing? Or somehow allowing users to flip a switch and have everything magically change to the $9D00 addressing? I know somewhere you mentioned you wanted to create a DOS3.3 symbol file for use with AppleWin, and certainly it (or a version of it) should be based on $9D00.

Correct. Which is why I'll also be providing AppleWin symbols at the final $9D00 range. :-) I've added a new section 3.3 for where these will go. It is trivial to add $8000 to all the addresses.

That is why I started this project in the first place! To get symbols for EVERY DOS 3.3 function and variable.

That's not a bad idea! I can put that in the top right in the "color/monochrome" option:

Address
(x) Master $1B00
( ) Slave $9B00

Internal notes for myself ...

• Prefix all AppleWin symbols: DOS. for DOS 3.3 -- we can still use D32 (DOS 3.2) for the symbol tables if we ever do DOS 3.2
  • We have 11 characters visible for symbol names in the debugger.
  • Longest DOS 3.3 symbol name is 8 characters
  • Which means 1 character will be hidden unless address/opcodes column is toggled off.
• Need to have symbol tables for:
  • [ ] Pronto DOS
  • [ ] Diversi DOS
• Markup <a class='d' variable declarations with coords='16' for 16 bytes. i.e. DB TABLE B64D:B65C, etc.
  • [ ] Fix AppleWin's debugger to make equal sign optional for DB to be consistent with SYM and ASC. i.e. DB TABLE = B64D:B65C See: AppleWin #449
• Markup <a class='d' variable declarations with coords='-12' for 2 byte text, i.e. ASC VOLMES = B3AF:B3BA
