RTL Logic

 If you look at Al's spec page, see 017_MC715 or page 18.
It states:

Each may be used independently, paralleled for increasing
the number of inputs ( subject to loading rules), or
cross-coupled to form bistable elements.

 So, as you can see, it was allowed to tie outputs together
with some restrictions.

>I don't see how doing a wired-and is possible when RTL includes a pullup
resistor on each output. You would get to a point where an individual output
transistor would not be capable of sinking all the "low" current.
>You can get a basic idea of the logic families here...
