KEEP PRODOS

MCOPY PRODOS.MAC
|
|
|
|
* disassembly of prodos version 2.0.3
|
|
* can be compiled with the orca/m assembler
|
|
* which produces an output file PRODOS (type = EXE)
|
|
* address refs beginning with 'L' were generated by orca disassembler
|
|
* address refs beginning with 'H' were added manually
|
|
|
|
* last edit: 01/24/13
|
|
|
|
* map of the object modules within prodos exe are as follows:
|
|
|
|
* $2000 mli_0 mli loader/relocator
|
|
* $2C80 ram_1 installer for /RAM
|
|
* $2D00 ram_2 /RAM driver in main lc
|
|
* $2D9B mli_3 interrupts
|
|
* $2E00 mli_1 global page
|
|
* $2F00 tclock_0 Thunderclock driver
|
|
* $2F80 cclock_0 Cortland clock driver
|
|
* $3000 mli_2 xdos mli & block file manager
|
|
* $5100 ram_0 /RAM driver in aux mem
|
|
* $5300 xrw_0 disk core routines
|
|
* $5A00 sel_0 dispatcher
|
|
* $5D00 sel_1 enhanced quit code (Bird's Better Bye)
|
|
* $6000 sel_2 GQuit dispatcher support
|

************************ IMPORTANT ************************
|
|
* *
|
|
* 1. In the language card area, the $D000 areas overlay. To *
|
|
* determine which bank is active requires that the main bank *
|
|
* has a CLD ($D8) at $D000 and the alternate bank does not. *
|
|
* $D000 in ROM = $6F, LC bank1 = $D8, LC bank2 = $EE *
|
|
* *
|
|
* 2. Location $E000 is used to determine the state of ROM vs. *
|
|
* language card. Therefore, the value of $E000 in the MLI *
|
|
* and ROM must differ. *
|
|
* *
|
|
* 3. In the section MEMMGR, the routine CALLDISP must access *
|
|
* the other $D000 bank so it MUST reside ABOVE $E000 in the *
|
|
* language card area. *
|
|
* *
|
|
* 4. The Disk II routine xrwtot MUST reside on a page boundary *
|
|
* to distinguish it from a ram-based driver. *
|
|
* *
|
|
* 5. In the /RAM driver ram3, the byte at $FF58 MUST be an rts *
|
|
* ($60) so the routine JSR $FF58 to determine an I/O card's *
|
|
* slot still works when the language card is switched in. *
