WP 34S - best cable layout ?

[Dave Frederickson]

Depends on how you define "best". Are you looking for cheap, bells and whistles, or reliability?

For reference, here's the 20b/30b cable guide.

For hardware I recommend Harald's board, described here.

For a connecting cable, if you're concerned about reliability, I made this connector that doesn't require any soldering on the plug end.
