Thanks again!  I'll pass this on to Eric Raymond, current maintainer of the Jargon File.

I heard from Mike Cowlishaw about the IBM jargon items "branch to Fishkill" and "branch to Owego"

They reflect a set of site pairs within IBM in which one site designed and made hardware (Fishkill, Owego) and another site designs and builds software (Kingston, Endicott).  To the software folks the hardware world was esoteric and weird, hence the branch targets for weirdness were the hardware sites.

Mike Cowlishaw's IBM Jargon and General Computing Dictionary, Tenth
Edition <http://www.comlay.net/ibmjarg.pdf> was probably the source for
this -- it includes both "branch to Fishkill" and "branch to Owego" with
exactly this definition.
