Thanks to all who helped to clarify how the topics work here, and for the kind suggestions
on apps choices.
A special reply to Steve is in order here, in regards to amusement rides running
on Windows. Yes, I know that THIS message is ironically 'way off topic, and I assure
you it won't happen again. But I felt it critically important no one felt they were
regularly getting on amusement rides that are run by Windows. That would be the start
of a very nasty rumor, owing to me.
TYPICALLY this is not done. There are a number of "Boiler Plate" specifications for
what is termed "Life-Safety" level of equipment design. I helped write them. One
of the fundamental rules is that Life-Safety equipment be operated by non-crashable
Programmable Logic Controllers, or PLC's. Allen-Bradley makes the most widely-used
one.
Various companies developed utility programs to create, download, and real-time monitor
the "Ladder Logic" PLC program that actually run the rides, which are executed from
the PLC's NVRAM. The utility programs were for a long while exclusively DOS-based
programs. Windows98 is the last version that can operate this software while still
functioning in today's advanced file-handling world. Therefore, the DOS/Windows98
program is more of a development compiler and monitoring system utility. So ride
the rides in peace.
Again, my apologies for the deviation. I will stay on topic in my future questions,
and my apologies for any trouble it created.
