You're talking about the power pins?

They are typically found at the opposite corners of the chip, "bottom 
left" being GND and "top right" being VCC. Not only for 74xx, but for a 
great number of stuff commonly found in DIL packages (memory ICs, 
microcontrollers and what-have-you-nots).

The numbering seems to have evolved independently from this, following a 
"U" shape starting at "top left". This is /always/ the case for DIL 
packages (with problems arising only if pins are completely left out; I 
think they're counted as if they were there).

Indeed this, combined, is not very intuitive.

Let me guess: valves

Seems you are a few years before into computers. I started programming 
on (I think) a TRS80 in 1978 or 1979. Although I might have encountered 
a computer before that at my summer holiday job, which had something to 
do with punched cards. My first serious mainframe was a CDC Cyber 
stationed at SARA, the computer facility in Amsterdam in 1982.
I just found some stuff from that era. Yip does bring back memories.

My first real job was with Honeywell, in 1969. Where I tested PCBs for the H-416
and H-316. The first computer I ever saw was a valve analog one at Glasgow
University a couple of years earlier. I spent about 10 years working in computer
maintenance in factories before working offshore. Which was a very different
life :)
Now I skive around working in SAP configuring the Plant Maintenance and Customer
Service modules.

Hey, another off-shore guy. Coincidence? I guess so.

Off to Google... Ok, SAP is that sort of company. Having plant and sap 
in one sentence might suggest something else. Just kidding, I simply had 
not heard of it. And I assume skive means something with a lot of 
travelling.

Shay works offshore in the Mexican Gulf IIRC

No, referring to the Shay of the line below.

I think he is grounded again.

To show of my lack of knowledge I decided to use an expression that 
probably would not mean 'he has a job on land now' not even for offshore 
people. I think I succeeded.

"Grounded" specifically means not allowed to by an authority, amongst other
things. A pilot or plane can be grounded by weather or for safety reasons. A
child may be grounded by its parents as a punishment.   
If Shay were working onshore, in Britain, we would say that he is "on the
beach". But I'm sure he will let us know when he next pops in.
