In the early 7D14's U329 was a Tek made IC, 155-0046-00. That became obsolete and from B050000 156-0377-00, MC12090P,
was used instead on a redesigned circuit board. The new IC was not a direct replacement so for replacement a Parts
Replacement kit, 050-0638-00, which contained only the redesigned complete circuit board, 670-0993-01 had to be used.
The original 155-0046-00 was not used in any other instruments.
