Your memory is faulty. I wasn’t a volunteer. I was under contract to Ziff-Davis for an every other week article and was surprised at how well they paid for 500-750 words. Most were published in PC WEEK but a few made it into PC MAG. This was in the mid-1980s. That was when I started messing around with PASCAL for the fun of it. The one I read was a beta test review of some program. |

I started by teaching myself, with the help of a couple of manuals, rudimentary PASCAL, and I was "tutored" by a couple of buddies, one of whom was a high-level computer scientist and the other, a systems analyst. No biggie, but, yes, I took some university courses in the field. So, once again and, as always, you are...wrong. |

His column was called "Chaos Manor" and had a wide following. https://en.wikipedia.org/wiki/Jerry_Pournelle Our friend Harree was never anywhere close to being on the same technical level as their regular contributors, and frankly I never remember seeing his name even though I was a regular reader. --- This email has been checked for viruses by AVG. http://www.avg.com |

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. |

Every month they sent you a bunch more parts and a book of things to try. When you were all done you had an amplifier, a tuner and a few other things that ended up being a regenerative AM radio among other things. It was all done with 3 or 4 tubes. I used the amp long after I decided a 5 bottle table radio was a whole lot better. I didn't really start playing with transistors until I got to IBM although I knew a lot about them from school. As soon as I figured out IBM was scrapping the returns, they did not get much back on the cards. I did learn what was failing on the card tho because I was removing and testing components for my projects. It saved us a few times because I was able to fix a card if we could not get one right away. |

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. |

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. |

Same as an 74ls74 ic. 1" x .5" The last school I went to that talked about what was on the cards was 1401 support. The cards were actually made to be fixed and they had test points on the outside edge of the card so you could scope the bases of the transistors with the card installed. I was the only guy I knew who ever fixed one. We could scope them, but mostly used an ohm meter and checked the diodes and transistors. The 315 RMC would get a random error and we would rattle the boards looking for the broken leg. They used a water based cleaner after the wave solder machine and the legs would corrode through. We used a scope for just about everything. I was not really convinced checking with a meter was anything like watching the circuit in operation and figuring out why it wasn't. Some time the fault was just that it was switching slow and you had a ramp, not a cliff or just not a full level shift. That can give you all sorts of intermittent failures. |

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. It's worse than that. Those tiny little chips contain a whole lot more than just gates. The days of building logic circuits using gates in dedicated chips is pretty much gone. Now the vast majority is done with programmable logic devices (PLDs) and their variants where you just design the logic in an app and assign the inputs and outputs to the pins, then program the chip to perform that operation. A complex programmable logic device (CPLD) can contain 10's of thousand of logic gates, and is programmed after being soldered on to the board with serial data (usually JTAG) while in-circuit. === Amazing stuff, absolutely amazing. Electronics has come so far in my lifetime that it has far surpassed anything I could have imagined. In 1957 I added a one transistor audio amplifier stage to a crystal set that I had previously built as a cub scout. It worked surprisingly well considering that it was built on a small 2x4 cutoff and had no soldered connections. A friend of mine borrowed it and entered it in a science fair without me knowing about it. He won 1st place --- My start in this was a "kit" course when I was about 13-14. Every month they sent you a bunch more parts and a book of things to try. When you were all done you had an amplifier, a tuner and a few other things that ended up being a regenerative AM radio among other things. It was all done with 3 or 4 tubes. I used the amp long after I decided a 5 bottle table radio was a whole lot better. I didn't really start playing with transistors until I got to IBM although I knew a lot about them from school. As soon as I figured out IBM was scrapping the returns, they did not get much back on the cards. I did learn what was failing on the card tho because I was removing and testing components for my projects.

So you hung out with the people you call the crooks and never met any actual working people. In those days, Citicorp was run by a liberal arts grad who first noticed my client because of well-received statistical analyses and reports of U.S. housing and commercial markets we published for the client. Everyone associated with researching, compiling, and writing the narratives was a liberal arts grad. The bank bought the client for $29 a share in 1970 or so when it was trading OTC for $5 a share. Even I was able to make a few bucks on the sale. Citicorp later had to divest itself of the client for antitrust reasons. |
