This is !SSystem, version 1.23 (27 Mar 1996)
This program is one that demonstrates the movements of planets in the solar
system, the ratios of the speeds and orbital size being fairly accurate. No
attempt has been made to make the orbits true ellipses, they are describing
purely circular motion.
The program performs best in modes of 16 colours such as mode 12, 20, or 27,
and rather than spend too long in improving the program, I suggest that you
use one of these modes to reduce the problem of flickering.
The resulting program has been 'shrunk' using !BasShrink by John Wallace.
Thanks go as usual to Paul Hobbs who provided the RiscOs program !Shell
around which this program was written.
