1a4d804a5f Added cursor-flags initiation. 
The CBM510 runs programs in a non-system memory bank. It has its own zero page. Some things are copied from the system zero page; but, the cursor flags weren't copied. So, the cursor always blinked. That bug sometimes left cursor ghosts (reversed spaces) at the end of lines.

1347947f0d some nicer debug messages 2013-06-25 00:48:26 +02:00
Greg King
e63bf1cde1 Used a library-reference method to calibrate lightpen drivers. 
The mouse reference is a pointer.  If it's NULL, the driver uses a default.  If it's non-NULL, then it points to a function that the driver can call.  That function will adjust the driver's calibration value.  It could ask the user to adjust the pen; or, it could read a file that holds a value from a previous calibration.

Application writers can choose how it's done: a function that's provided by the library, a custom function, or nothing.

619b215260 Added library reference em_libref to EMD interface. 
Occasionally dynamically drivers suffer from not being to refer to
content in the C library. Therefore I added a mechanism to allow
a C library for a certian target to define a symbol that will be
handed over to dynamic drivers for that target. Then the drivers
can use their refernce to that symbol to access content in the C
library.

7024e2789d Explicitly set search paths for libraries build. 
The libraries build is prepared to work with binaries not part of the current
working tree. But in this case the default search path surely points to some
other working tree. Even the binaries in this working tree might have been
compiled with non-standard builtin search paths.

Anyway when building the libraries we want always to use the headers from
the current working tree. Therefore we want to set them explicitly. Instead
of setting all in all five paths on the command lines of ca65, cc65 and ld65 I
opted to just set the single environment variable.

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.

56b6dcf814 Brought back mouse driver source code. 
The mouse driver source code in question was removed two years
ago with commit 6cbbe66c87.
It seems however desirable to have it around visible in the source
code tree for reference purposes.

98c47d1877 Introduced target 'atarixl'. 
The target 'atarixl' is to be used for Atari XL (and better) machines.
It will disable the OS ROM and enable the Shadow RAM available on
those machine.

Note: This commit is only the inital step towards for this goal that just
replicates the target 'atari' as a starting point!

2e8a65bda4 Renamed Atari drivers. 
As a preparation for the introduction of the 'atarixl' target it is
necessary that all drivers have a base name...
- no longer than 7 characters
- with a common prefix
