Complete redesign of the CBM610 support. Use wrappers to call the kernal in bank 15 instead of implementing kernal functionality within the cc65 libs (eats performance but is much smaller and simpler). Improved startup/shutdown code allows a return to the system bank without calling the BASIC cold start vector. git-svn-id: svn://svn.cc65.org/cc65/trunk@2793 b7a2c559-68d2-44c3-8de9-860c34a00d81 2003-12-20 23:13:26 +00:00			`;`

Made Olivers devnum patch (r4588) work with the PET-II models. On these machines, the program runs in a separate 64K bank, and zeropage variables need to be copied from the system bank into the execution bank to read by a simple load operation. The change is currently untested! git-svn-id: svn://svn.cc65.org/cc65/trunk@4597 b7a2c559-68d2-44c3-8de9-860c34a00d81 2010-02-20 19:46:51 +00:00			`.globalzp sysp0, time, segsave, ktmp, CURS_X, CURS_Y, RVS, DEVNUM`

Design change: Do keyboard polling internally without calling the kernal in the system bank. For one this performs better (several %), second it allows to handle the function keys in conformance with other platforms. Without the custom keyboard routine, we would have to apply some more magic to the function keys to make them work as with other cc65 targets. git-svn-id: svn://svn.cc65.org/cc65/trunk@2811 b7a2c559-68d2-44c3-8de9-860c34a00d81 2003-12-21 18:43:25 +00:00
