Abstract
Abstract In order to be able to adapt an electronic circuit board apparatus designed for a particular IC chip configuration to accept other chips to perform the same function, the socket for the IC chip is provided with a set of jumper terminals coupled to selected ones of the socket so that in the event the IC chip for which the IC chip was designed is not available, the circuit board can use other IC chips by connecting the jumpers to in effect redefine the socket. In addition, redundant parallel circuitry and IC chip sockets can be provided on the circuit board with each IC socket being wired to accept a variety of functionally identical IC chips.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
In a printed circuit board having a plurality of first integrated circuit chip sockets mounted on sets of socket terminals on said printed circuit board, and printed circuit wiring electrically connected to said socket terminals, respectively, in a predetermined pattern, the improvement comprising, at least one redundant socket terminals therefor on said printed circuit board, printed circuit wiring means connecting said set of redundant socket terminals in parallel to one set of said sets of socket terminals so that in the event the integrated circuit chip for which said one of said first integrated circuit chip was designed is unavailable, a functionally equivalent integrated circuit chip can be received in said redundant integrated chip socket.
Claim 2
Dependent Claim
115 words
In a printed circuit board having a plurality of first integrated circuit chip sockets mounted on sets of socket terminals on said printed circuit board, and printed circuit wiring electrically connected to said socket terminals, respectively, in a predetermined pattern, the improvement comprising, at least one redundant socket terminals therefor on said printed circuit board, printed circuit wiring means connecting said set of redundant socket terminals in parallel to one set of said sets of socket terminals so that in the event the integrated circuit chip for which said one of said first integrated circuit chip was designed is unavailable, a functionally equivalent integrated circuit chip can be received in said redundant integrated chip socket.
Claim 3
Independent Claim
83 words
A method of avoiding production delay in the manufacture of electronic circuit boards due to unavailability of specified integrated circuit chip components for which the electronic circuit board was designed, comprising, constructing the circuit board with redundant printed circuit paths relative to integrated circuit chip sockets on said circuit board for receiving said specified integrated circuit chip components, providing connection points for discrete external components to be connected to said redundant printed circuit paths, in the event of unavailability of said specified components.
Claim 4
Independent Claim
83 words
A method of avoiding production delay in the manufacture of electronic circuit boards due to unavailability of specified integrated circuit chip components for which the electronic circuit board was designed, comprising, constructing the circuit board with redundant printed circuit paths relative to integrated circuit chip sockets on said circuit board for receiving said specified integrated circuit chip components, providing connection points for discrete external components to be connected to said redundant printed circuit paths, in the event of unavailability of said specified components.
Claim 5
Dependent Claim
45 words
