HP-25/SR-56 Identical Conditionals

[Gene]

I suspect not, since they were made by competitors... unless TI decided to copy the ideas of the HP-25 team.

But the SR-56 had the independent "t" or test register while the HP-25 had dedicated conditional tests of X against 0 and X against Y. The SR-56 simply compared the displayed value (X) using =, not =, >= and <, to the value of the "t" register, which may have held a zero or non-zero value.
