Hi John,
I'm not at home where I have a paper manual, but I could download the BAMA manual here. It looks like we are talking about different things. At page 102, figure 8-11, all 3 ICs are shown, U722, U842 and U416. The A1 board layout is shown 3 times in the pdf and all 3 occurences show those 3 ICs. I didn't check traces, so I don't know whether the FP control is really connected to the IC which is labeled U722 at the board.

No Albert, nothing this end.
I confirm yr comment about the "big 7", mine is like that , the 7 over
writes the two (blank) white squares by a big margin
Ive spent some time tracking down where my download of the 7B80 manual
came from.(between efforts at pulling the engine out of my car, would be
nice if they made it pluggable like an IC with a socket)
Its from BAMA . if you download this and have a look it will be self
explanatory.
On page 101 the schematic says U722 for the FP cal set pot IC and etc.
On page 102 is the board drawing for above. There is NO U722 on it, but
U 841 is drawn in its place. The other two ICs are correctly designated.
The "page numbers" quoted above are what my reader says on screen ... no
actual manual page numbers appear on the scanned schematics etc for this
download.
Were you reading from a "real" TEk manual, Albert ? Whatever your case
yr manual would be better than the BAMA download one if yours give the
same IC designator on each of the drawings.
Best Rgds
John
