These are distributed with a "scaled-down" version of the Manx Aztec C65
cross-development environment for an Apple II with 64K of memory running
Apple DOS 3.3. A modified Graphics link library is provided with this
"scaled down" version which extends C65 to support the use of bit-mapped
graphics images and sound routines.

Background

The "Little Running Steps" Collection consists of 10 disk images containing
English and French versions of four PRODOS programs written by Canadian
Software Developer Bill Buckels in the early 1990's for use in Elementary
Schools.

The IBM-PC versions of these programs were developed by French Canadian
"CourseWare" developers Denis Coulombe and Robert Boivin on behalf of
Centre de recherche appliquée pour l'ordinateur (CRAPO) in the late 1980's
and marketed to schools across Canada as part of a six program set called
"Collection Les Petites espadrilles".

The Apple II versions were written in their entirety by Canadian Software
Developer Bill Buckels, on the IBM-PC in the C programing language using
the Manx Aztec C 6502 Cross-Compiler.

The Manx C compiler provided a rudimentary Graphics Library, but came
nowhere close to what Bill needed to complete the four programs in the
"Little Running Steps" Collection so he set to work to create the graphics
routines that the Apple versions needed.

Bill developed his own Apple II graphics file formats and programmed his
own set of conversion tools which he ran on the IBM-PC to produce the Apple
II graphics after creating and editing these in IBM-PC format to suit the
Apple II display. He did this in conjunction with writing his Manx C
graphics library.

The sample programs on these two disks are by-products of that effort, and
extend that effort from ProDOS 8 back to DOS 3.3.
