074e10d288 Adapted, to the c64 target, the INIT-segment overlay scheme from the apple2 targets.
When a program starts running, INIT is moved from one place to another place.  Then, INIT's code is executed; and, the first place is re-used for variables.  After the INIT code has finished, the second place can be re-used by the heap and the C stack.  That means that initiation code and data won't waste any RAM space after they stop being needed.

6217f8fa3a Made the Commodore version of exec() work in programs that are so big that they load into all of BASIC RAM.
The function won't cause an "out of memory" error.

d0fb1fe0ae Added the model-specific addresses that the CBM exec() needs. 2013-08-25 00:43:23 -04:00

051c21726b Added Inkwell lightpen drivers for the C64 and the C128.
They use the mouse driver programming interface.

Added a test program for lightpen drivers.  Now, it knows about only those two drivers; it will need updating when others are added.

72f456536f Turned the 'ST' status byte into a symbol resolved by the linker in order to allow to use it from code living in the 'cbm' directory.
Moved getdevice.s from 'c64'/'c128' to 'cbm' making use of the new 'ST' setup.

5c5d01d84a Moved most platform assembler includes into asminc, so they will be available
in the distribution. 
Added --forget-inc-paths to the command line of the assembler in the
Makefiles, because the assembler does now have builtin paths and will find
include files from an installation first.
Hopefully fixed any problems that arose from the two changes.
