Agreed, this looks like to be a top candidate, if not the first choice.

There was an issue with the PSIM that resulted in a slower-than-anticipated
ALLDACSOUT routine, IIRC. No idea if this was a PSIM-specific thing that we
could avoid.

Seems to me that these are implementation-specific features, i.e. each
builder will have his/her own requirements. Having said that, these are good
ideas.

I assume that Harry Bissell's offer to lay out a PC board for something like
this still stands, in case we eventually need such a resource.
