000000r 1 ; Microsoft BASIC for 6502
000000r 1 ;

000000r 1 ;
000000r 1 ; This is a single integrated assembly source tree that can generate seven different versions of
000000r 1 ; Microsoft BASIC for 6502.
000000r 1 ;
000000r 1 ; By running ./make.sh, this will generate all versions and compare them to the original files
000000r 1 ; byte by byte. The CC65 compiler suite is need to build this project.
000000r 1 ;
000000r 1 ; These are the first eight (known) versions of Microsoft BASIC for 6502:
000000r 1 ;
000000r 1 ; Name Release MS Version ROM 9digit INPUTBUFFER extensions .define

000000r 1 ; MicroTAN 1980 Y Y ZP - CONFIG_2C
000000r 1 ;
000000r 1 ; (Note that this assembly source cannot (yet) build AppleSoft II.)
000000r 1 ;
000000r 1 ; This lists the versions in the order in which they were forked from the Microsoft source base.
000000r 1 ; Commodore BASIC 1, as used on the original PET is the oldest known version of Microsoft BASIC
000000r 1 ; for 6502. It contains some additions to Microsoft's version, like Commodore-style file I/O.
000000r 1 ;
000000r 1 ; The CONFIG_n defines specify what Microsoft-version the OEM version is based on. If CONFIG_2B
000000r 1 ; is defined, for example, CONFIG_2A, CONFIG_2, CONFIG_11A, CONFIG_11 and CONFIG_10A will be
000000r 1 ; defined as well, and all bugfixes up to version 2B will be enabled.
000000r 1 ;
000000r 1 ; The following symbols can be defined in addition:
000000r 1 ;
000000r 1 ; CONFIG_CBM1_PATCHES jump out into CBM1's binary patches instead of doing the right thing inline
000000r 1 ; CONFIG_CBM_ALL add all Commodore-specific additions except file I/O
000000r 1 ; CONFIG_DATAFLG ?
000000r 1 ; CONFIG_EASTER_EGG include the CBM2 "WAIT 6502" easter egg
000000r 1 ; CONFIG_FILE support Commodore PRINT#, INPUT#, GET#, CMD
000000r 1 ; CONFIG_IO_MSB all I/O has bit #7 set
000000r 1 ; CONFIG_MONCOUT_DESTROYS_Y Y needs to be preserved when calling MONCOUT
000000r 1 ; CONFIG_NO_CR terminal doesn't need explicit CRs on line ends
000000r 1 ; CONFIG_NO_LINE_EDITING disable support for Microsoft-style "@", "_", BEL etc.
000000r 1 ; CONFIG_NO_POKE don't support PEEK, POKE and WAIT
000000r 1 ; CONFIG_NO_READ_Y_IS_ZERO_HACK don't do a very volatile trick that saves one byte
000000r 1 ; CONFIG_NULL support for the NULL statement
000000r 1 ; CONFIG_PEEK_SAVE_LINNUM preserve LINNUM on a PEEK
000000r 1 ; CONFIG_PRINTNULLS whether PRINTNULLS does anything
000000r 1 ; CONFIG_PRINT_CR print CR when line end reached
000000r 1 ; CONFIG_RAM optimizations for RAM version of BASIC, only use on 1.x
000000r 1 ; CONFIG_ROR_WORKAROUND use workaround for buggy 6502s from 1975/1976; not safe for CONFIG_SMALL!
000000r 1 ; CONFIG_SAFE_NAMENOTFOUND check both bytes of the caller's address in NAMENOTFOUND
000000r 1 ; CONFIG_SCRTCH_ORDER where in the init code to call SCRTCH
000000r 1 ; CONFIG_SMALL use 6 digit FP instead of 9 digit, use 2 character error messages, don't have GET
000000r 1 ;
000000r 1 ; Changing symbol definitions can alter an existing base configuration, but it not guaranteed to assemble
000000r 1 ; or work correctly.
