[sdiy] Motorola MC series logic

[Ray Wilson]

Found this about the chip...

The 1969 Motorola Semiconductor Data Book lists the MC1806 as
DTL quad 2 input AND gate (no inversion), pinout as you inferred (outputs 
3,6,8,11).

The 1800/1900 numbers seem to be additions/extensions to the standard
800/900-series DTL.
(So MC1806 and MC1906 are the same function but different temperature 
ranges.)

(Part number MC806 was already used in the RTL series.)

(Also listed in the 1973 Moto Ref Vol 1)

Looks like it's DTL (diode transistor logic... old old old stuff)
