RE: Transistor Replacement
1854-0071 is used several times inside the 97.
Card reader Q1, keyboard Q4, logic Q3. In all tables in the 1976 manual it is listed to be NPN The only confusing is the error in figure 4-23 where it is drawn to be PNP. Tony (Nixon) once did some corrections to the manual and published on his website. See the picture Tony posted before |
