Abstract

Complementary transition boards 10 and 12 can be positioned on either side of memory plane 14 to maintain equal core line lengths to plug-in circuit cards 16. Every core line 18 is terminated at each end by a pin 20 which mates with circuit cards 16. The lengths of leads 22 and 24 to the core lines complement one another. That is, if lead 22a to a particular core line 18a is short on one transition board 10, lead 24a to the same core line 18a on the other transition board 12 is long. In this way all the leads can be made identical in length as shown.
