John (and everyone),
Here is my comment on the higher expense of the Basic Atom Pro system,
FWIW....
A few years ago, Grant was besieged with overhead cost issues relative
to front panel fabrication, and the financial and managing costs of
having to order several units at once to keep costs down, etc. - now
he is using .fpd files and Front Panel Designer to fabricate his front
panels - each panel costs more, but can be ordered piece by piece,
including customizations.
I believe that the Basic Atom Pro is like front panel designer in this
scenerio - more expensive, but it offers many more people an
opportunity to contribute.
In fact, using the PSIM as a developement platform, we have a fairly
evolved forum for testing new ideas and applications; with both
sophisticated writers and end users having the same hardware, trouble
shooting, modifications and revisions can easily be done between
author and beta tester very efficiently.
For example, when Woody Wall created the Shift Register Program, I
made some suggestions, based on how I used my pair of Serge ASRs; he
made a few adjustments for me and sent me the new file, and that
application is STILL in one of my PSIMs - the other is Mike's
quadrature oscillator. I could easily see creating permanent,
dedicated modules for these programs....
