In item I am curious as to whether the
gold islands on the top-side are functional test-points giving electrical
access to the underside pins?  Was there a clip designed to attach to the
top-side of these chips for use in circuit analysis?  Was this design unique
to Russian manufacture (I don't recall ever seeing this design previously)?
