- The AmigaDOS version of Accrete is as unaltered a port as I could manage. The
- most significant changes were in the random number generator initialization
- routine and in the definitions relating to just how large an int is on the
- Amiga. Unlike the Apple ][ version, this version is compact and fairly quick.
- What takes 15 minutes on a 1Mhz 6502, takes less than a minute on an A3000/25.
- Given this runtime speed, I saw no real need for a version that supported
- the 68881 and 68882 math-coprocessors.
-
- Just as in the original, this program dumps its output to a file named
- "New.System" but it does *not* create an icon, even if launched from the
- Workbench. There is presently no way to override this default. There are
- a couple of compile-time options, however. The proprocessor symbols, SILENT
- and VERBOSE are just as they sound. The default mode prints a single dot with
- each attempt to create and resolve a planetessimal, the silent mode prints
- abolutely nothing during a run, while the verbose mode spews forth with a
- couple of (short) lines about each attempt to inject proto-planet into the
- solar system. Accrete works from either the CLI or the Workbench. Note
- that if you launch Accrete from the Workbench, you will have to close the
- console window yourself.
-
- Scientific references to the techniques used to generate planets and their
- star systems are provided in the code and in the other read.me files. I
- made no attempt to verify the correctness of any of the mathematical code; I
- simply fixed up the word size problems as well as the non-random random
- number problems.
-
- I found no copyright notices in the source code I started with, so I didn't
- bother to put additional notices in any of it. The only file *I* created
- from scratch was the Makefile and the only distribution restrictions I have
- placed on it prohibit commercial uses, and are mentioned (briefly) in that file.
