I wondered if it was fair to list the DEC 23B00A2, etc that hold the ucode
as separate parts; they might have been a bunch of 256x4 PROMs, and the
separate part numbers were just for the different programming. (Whether
differently programmed PROMs count as 'different' parts for the purposes
of this table I leave aside.)

Looking at my M7232 card, though, I think they may be masked ROMs; the
only part number on them looks like a manufacturer applied one with the
DEC number.

Interestingly, about a third are MMI parts, and the rest are NS. I wonder
if neither manufacturer had enough capacity alone, or if DEC just wanted
multiple sourcing. (The parts appear to be basically the same, in terms of
speed, format, etc so it appears either could have provided any of them,
modulo the programme.)

https://xkcd.com/979/

There are a couple of things now where I know that if I try to find
sources, I'll find myself.

The details of how id Software's game /Quake/ killed Cyrix, the CPU
company, because Quake used a very clever method of interleaving FP
ops with integer ops that didn't use the same registers, allowing the
Pentium core to essentially run them at once. The Cyrix 6x86 core was
quicker -- I bought one myself, what more can I say -- but it couldn't
interleave FP and int ops like that, so it ran Quake like a dog.

And as Quake was *the* most demanding game around in 1996 or so, and
had a super convenient built-in "timedemo" feature, all the magazine's
benchmarks used Quake. So 6x86s got hammered, even though on literally
*ALL* OTHER X86-32 CODE THEY WERE QUICKER, they got bad reviews, and
Cyrix ended up getting acquired by Via.

Or the problems with AMD fglrx on a Toshiba Satellite Pro P300A.
That'll be me, too.

The weirdest one, though, was when I was given the honour (?) of
moderating my first item at the World SF Convention. It was a
collection of silly games. I'd never heard of one of them. I Googled
it. I got my own blog as the № 2 or № 3 hit.

_That_ was odd.

Foghorn. Because of his loud voice.

https://en.wikipedia.org/wiki/Foghorn_Leghorn

A foghorn is a big loud, well, horn...

https://en.wikipedia.org/wiki/Foghorn

And a Leghorn is a kind of chicken.

https://en.wikipedia.org/wiki/Leghorn_chicken

Leghorn chickens are from Livorno in Italy which is apparently
anglicised as "Leghorn", at which point I run out of explanations.

Gotta say, though, Ben, it didn't _look_ like a joke...

A related anecdote (that must surely happen often to ARD, Chuck, Allison, 
and a few others), . . .
A friend of mine did hobbyist holography, with a ton of sand in a waterbed 
frame on stacks of tires, . . .
There used to be only one REAL professional photography supplier in the 
area, where you could get sheet film, glass plates, etc.
One time, she noticed an Eastman glass plate emulsion that she hadn't seen 
before, so she asked the staff about it.
"Well, I personally don't know anything about it, but I hear that we have 
a customer who knows EVERYTHING about that stuff, and we'll get them in 
touch with you!"
When she got home, there was a message on her answering machine, "Hi, this 
is George at Alpha Photo.  We have a customer who wants to know about a 
new Eastman glass plate emulsion.  Would you mind telling them what you 
know?"


Guess what?  YOU are the expert that they will put you in touch with.

I'll look at that site later, as finding any kind of intersting page

What I have seen a lot lately, is that you get a search hit, click on

and get a "We will display NOT this page for you because  ". Is that
