SixtyPical/eg

This directory contains SixtyPical example programs, categorized in subdirectories by machine architecture.

rudiments

In the rudiments directory are programs which are not for any particular machine, but meant to demonstrate the features of SixtyPical. Some are meant to fail and produce an error message. Others can run on any architecture where there is a routine at 65490 which outputs the value of the accumulator as an ASCII character.

c64

In the c64 directory are programs that run on the Commodore 64. The directory itself contains some simple demos, for example hearts.60p, while there are subdirectories for more elaborate demos:

• demo-game: a little game-like program written as a "can we write something you'd see in practice?" test case for SixtyPical.

• ribos: a well-commented example of a C64 raster interrupt routine. Originally written with the P65 assembler (which has since been reborn as Ophis).

  The second version of Ribos has been translated to SixtyPical.

• petulant: "The PETulant Cursor", a tiny (44 bytes) "display hack". Originally written in the late 80's. Rewritten with the P65 assembler (now Ophis) and re-released on April 1st, 2008 (a hint as to its nature).

  Translated to SixtyPical (in 2018), after adding some optimizations to the SixtyPical compiler, the resulting executable is still 44 bytes!

vic20

In the vic20 directory are programs that run on the Commodore VIC-20. The directory itself contains some simple demos, for example hearts.60p.

atari2600

In the atari2600 directory are programs that run on the Atari 2600 (4K cartridge). The directory itself contains a simple demo, smiley.60p which was converted from an older Atari 2600 skeleton program written in Ophis.

apple2

In the apple2 directory are programs that run on Apple II series computers (Apple II+, Apple //e). sixtypical's support for this architecture could be called embryonic.
