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
