Hi, The cc65 Atari docs say: "... This gives a usable memory range from $2E00 - $BC1F. ... The load address of $2E00 was chosen to accommodate having a DOS loaded and a driver that resides in low memory such as the 850 R: handler. ..." I saw a (seemingly working) linker config defining $1F00 - $FFFF: http://ataricc65lib.svn.sourceforge.net/viewvc/ataricc65lib/contiki-2.1/platform/atari/linker.cfg?view=markup Is it possible to explain with a reasonable effort, when it is plausible to lower the start address from $2E00? Is $1F00 a meaningful value? If yes, for which scenario? I presume the RAM end $FFFF was choosen to not restrict the linker "unnecesarily" in the case MEMTOP turns out to be very "high". I presume $BC1F was choosen as a reasonable default. If MEMTOP actually is somewhere different is it expected to be lower and/or higher than the default? Which scenarios / values are plausible? Thanks in advance, Oliver ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo@musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.Received on Sun Sep 26 12:58:15 2010
