Woah, woah, woah. What is this. Art-class for beginners?

90 dregree, then 45, then 90 again?

Sheesh! Amateur!

I was just teasing.

Personally, i was taught to use 45-degree angles - not for fear of losing electrons, but back in the earlier days of PCB, the copper 90'degree corners lifted a lot easier, leading to broken traces.

Hell, the pre-DCS schematics (that I have, anyways) literally have two chips listed as "U?". Apparently, the schematics were never corrected once the final board went to manufacturer.

In WMS defence there, the chip's 8designation* for that pin (i.e. What's marked in the datasheet) is VCC. However, if you follow the trace (which should always be done - never base net connections on what mfg's call/name chip pins) it is connected to the '+12A' signal.

I'm rebuilding a pre-DCS sound board (for my own use.. if it comes out successful, and others want it, I may have some made), and 99% of my time has been verifying what's on the schematic to what's actually on the board - not counting chips with multiple gates (i.e. 2 AND gates - I don't care if the schematics have the wrong fate listed.. Operationally it's still the same.)..

I agree - usually deliberate errors (like what used to be done on paper maps years past) were OBVIOUS once you caught it, but were small enough that unless you were looking for it, it wouldn't get noticed. (A driveway with a road name? A road that makes a sharp turn to the right and dead ends?)..
