From: N_Cook on 12 May 2010 10:29 Just for future reference , is there a general principle concerning pdf to text that can be applied. Not relevant now as got the thing repaired but in the process I was looking for the pinout of Sony CXD 3058AR and only found this reference. From the example I had in front of me Vss was pins 17,31,37,46,78,79 , easy to establish 112 pins in total I'm assuming a pinout of the IC appeared buried in this gibberish , presumably something else mixed in there as was horizontal to the CXD one (part only) http://www.scribd.com/doc/18318751/Sony-Hcdne3compact-Disc-Deck-Receiv ..

Where there is only the text version out there, derived from a not available pdf. Trying to reverse engineer one I did pdf to text myself. 80 pin chip data on pdf with 1 to 24 pins L to R along bottom and vertical text text read from right , then anticlockwise. The horizontal text appearing in the horizontal on left and right edges appears as though scanned from right to left, ie swapped over. Also grey tone blocking of Vcc and Gnd maked them get lumped together when appearing in the vertical script

I have done that a few times with some success.

You can download and read the whole pdf file from that link. The IC pinouts are quite readable. Colin @ CATronics |
