Here we go again. hehehehehe.

Another brain fart from Harry. I understand technical things are
beyond your comprehension but you don't need to be so proud of it.


I don't have any problems moving .jpg's to and fro. I know better than
to try to do so with my usenet provider in a "non-binary" newsgroup or
whatever was being tried that didn't work.

Oh, and I had more than 50 articles published in PC Week, PC Magazine,
BYTE and a few lesser pubs. I had a biweekly column in PC Week. Your
computer oriented technical articles consisted of...???

Uh huh. So If I go look at the archives of PC week or PC Mag I will
see a lot of "technical" articles from Harry Krause? We are not
talking about case styling and the feel of the keyboard are we?



They were probably letters to the editor.

In fairness, I remember reading something Harry wrote in some PC
magazine. He used to volunteer to do beta testing and provided feedback.

Yabut, he said he was published in BYTE. That was a highly technical
magazine written by very competent engineers. They published stuff like
schematics of computer circuits complete with timing diagrams and sample
code to perform complex functions. If true, they must have needed some
fluff filler piece because he doesn't have the engineering chops to
write anything that they would normally publish.


When it comes to computers, neither do I. :-)

I got a kick out of a visit from my younger son the other day. He
started a new job as a facilities manager for a company that uses
automatic, high volume packaging equipment. He took electronic
engineering courses when he attended MA Maritime but they only covered
digital logic circuits. They don't even teach theory anymore and vacuum
tubes, transistors, etc. are artifacts of ancient times.

One of the systems he's responsible for broke down due to a bad rotary
actuator. He was having a problem ordering a replacement because there
were two versions of it. One was a PNP type, the other a NPN. My son
had no clue what PNP or NPN meant. All he knew for sure was that they
had a magnet in them along with a small chip.

I explained he had a "Hall Effect" circuit and spent some time
explaining what PNP and NPN meant, drawing diagrams of transistors and
explaining what the base, emitter and collector were. Then I drew a
diagram of a vacuum tube with the cathode, screen grid and plate, while
explaining how it worked and the similarities in function to that of a
transistor that came later.

Now-a-days everything is on a chip the size of your little fingernail
and it probably contains a dozen or more and, or, nand or nor gates or
transistors used as gates.


I also have an analog background and still get headhunters contacting me,
as analog is needed now. The problem I saw years ago, was the university
taught digital, and did not seem to realize that the speeds even 15 years
ago required analog training. Even an early Pentium ran faster than any AM
radio frequency. Crosstalk and induced signals to adjacent lines were some
of our biggest problems.


That's not an analog problem, that's an RF problem.
When you're moving electrons around on copper traces on a PC board as
fast as a modern computer does, you can't make 90 degree turns with the
traces. The electrons can't turn that quickly and tend to flow off the
copper. Seriously.


I suppose all the dust that settles under the board are those dead
electrons. :-)




Good one. We had long cables to the disk drives. flat cables, and the
original designer put the clock line next to the data lines. If you sent
an FF the clock line got tripped. Not at the proper time, so an extra
clock pulse.
