True, but nand based logic RULEZ OK!

True, but nand based logic RULEZ OK!

How about nut-case logic? You seem to be the perfect candidate ;-)

Circa 1967, maybe.

After all, back then there was a limited selection of logic ICs. If
you needed something better, you often had to construct it from
the few common gate types. Indeed, in the days of RTL there was more
than one article about making your own simple RTL gates, so you'd
start with discrete components and build up from there.

By the time Don Lancaster wrote his "TTL Cookbook", circa 1974, those
equivalents were more about describing how the exotic gates like exclusive-or,
worked, rather than because anybody needed to build one up from a 7400.

My guess is that you've never designed with ECL.

Oh, Jim, must you be so ham-fisted in this game? You preempted me
asking, "But have you ever traded deMorgan sets with John?"

Cheers!

My guess is that you've never designed with ECL.

And my guess is that you never learned that positive logic NOR is
negative logic NAND...

Off your meds again Bloggsie? You're certainly off your rocker.

Excusez moi??? Your underlying assumption is that the physically higher
voltage is logic '1' and '0' on the physically lower. Do you lack the
brain power to ask yourself why this should be so, because there is
absolutely no reason for it whatsoever. Apparently Motorola did not
agree with you because their ECL databooks were full of those negative
logic tic things only they used. Any physically high input to a NOR
drives the output to physically low, but when you take physically high
as '0' and physically low as '1', that results translates into any
binary '0' input to the ECL NOR takes the output to a binary '1'. Looks
like a NAND to me!

Get a grip Bloggsie. Maybe you should take a chill-pill and reread
the thread. What a maroon!

Apparently you have taken one too many chill-pills. Time to dry out and
salvage what little is left of you...and the initial value was not all
marvelous to begin with.

Ah, how cute. Now put away your toys and take your nappie.
