Diode-transistor logic shortcuts?

[Artlav]

Greetings.

I'm making some experiments with DTL circuits, and i wonder if i missed something obvious when piecing the bits and facts about it from around the net.

Are there ways to reduce the number of elements in the circuit when multiple DTL gates are used?
For example, here is a NAND gate:

3 diodes (for 2-input case), 2 resistors and a transistor.

Now, say we have a bigger circuit, like this:

Are all of the elements in each gate mandatory there, or maybe some of them can be omitted?
I can't see any extra components, so there goes the question.

If you really had to use DTL then you have to use all the components.

However, if you just want the functions, then you can buy integrated circuits with 4 NAND gates on them which require no additional parts to work.

Like this one:

Those numbers are the pin numbers of the chip. These chips may cost less than a dollar, depending on where you buy them.

looks like you can do a wire-AND
