I'm likening your project to the modules being the sum/gain/integrate/etc
functions implemented in your "modules" with the "tapered pin interconnects"
being your "backplane". Is this approximately true? I.e., once you've
designed the individual modules, they'll be static (likely replicated)
with the real changes happening in the backplane wiring?

I think the one part you are not understanding is the purpose of the
patch panel. So, it would be like so:
- Fixed analog component modules — integrators, multipliers, and such
like — connect to the back plane. These modules are normally not
changed out except for repair, testing, and expansion.
- Cables from the patch panel(s) connect to the backplane. Wiring on the
backplane connects these cables to the component modules. This wiring
is not normally changed unless adding new patch panels or some
fundamental redesign of a patch panel port.
- The patch panels(s) have a bunch banana jacks allowing me to quickly
interconnect the inputs and outputs of the various analog components.
These connections are frequently changed — every time I set up a new
simulation.
This is how it works with my current analog computer I built, except
that there is no backplane. Rather, the wires from the patch panel
cables connect directly to terminal blocks on the analog component
modules.
