|  Re: Plus/4 issues trying to solve with Diag264
Finally the "new" 7406 is here but... replacing it did not solve the issue, that is still the same!
I have noticed that there is no continuity between pin 4 of the 7406 and the central pin of the transistor... I have again to admit my ignorance... I have read the schematics where the connection is direct... could it be there is something in the middle not shown or, what I suppose, a broken track (this Plus/4 had another broken track...)?
The issue is that I lose the track when it comes in front below the 8551... I do not know where it is supposed "to go"... can you help?
