Re: [N8VEM-S100:1694] 68K Parts List -- 2N3904 TO92-INVERT

[Paul Birkel <pbi...@gmail.com>]

Well, maybe.  I thought that the wire-lists correlated to the part foot-prints, thus that designation ought to relate to the footprint/pinout, not the logical-function in the circuit?

I guess that Andrew would be the one to clarify on that point?  (Of course, anyone who has already-built would know what they successfully installed there ... speak up please :->.)

All;

Regarding the 68K board, the s100_68K V3.lst file specifies that the 2N3904 is a "TO92-INVERT", however examination of the PCB and schematic seem to reveal the usual 1/2/3 E-B-C configuration, rather than the variant E-C-B configuration.  Is the "INVERT" designation in the lst-file incorrect and a standard 2N3904 should be used (e.g.: http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/2N3904TA/?qs=sGAEpiMZZMvAvBNgSS9Lqp8aB%2fMLlILd)?

Thanks,

Hi Paul,
  My guess is that label was used because the transistor is used as a simple TTL inverter and it may have nothing to do with orientation?

Jeff
