Diamond for Atari 8-bit computers in 6502 assembly
Author: dmsc
Category: Christmas Challenge
System: Atari 8-bit
Language: Assembler
Len source code: 662
Len exe file: 37
Len code only: 31
Instructions:
With the provided ATR floppy disk image, just boot and type DIAMOND to run
the program.
Description:
This program uses a table with values:
Table[] = 0 1 2 3 2 1 0 1 2 3 2 1 0 1 2 3 2 ...
Then, for each coordinate (X,Y), we draw a star where Table[X] == Table[Y+3]
To assemble the program, you can use the MADS assembler.
Comments:
To minimize size, this program directly calls the OS editor PUT routine, this
means it is only compatible with the XL OS used in Atari XL and XE computers.
