Folks at the tv station eventually got it figured out that when I was deep in a problem, it was best not to bother me since the teeth marks are so slow to heal. But each new hire had to learn that by hisself because when I am in troubleshooting mode, the train of thought from clue to clue to what part chipped a tooth is so easily disturbed. I have literally, with schematic in hand, had to start from scratch, reverifying the readings and waveforms for an hour before I got to the pin with the blown gate in a chip.
I don't repeat that willingly without getting testy. My first GM, the fellow that hired me, thought his opinion was gawd almighty & why didn't I have it fixed already. I was fighting with a 4 bit wide shift register that didn't always shift in the production video switcher, a GVG custom chip, and was trying to catch it red handed. He was back bugging me about it about every 10 minutes. About the 5th time I blew up, told him to go screw a rolling donut, the news COULD be done on a 2 channel switcher and that I was going home for the day. And did. He called me at home & I hung up. When I went in the next morning I went straight to his office and closed the door behind me, and laid it on the bottom line, which was if he thought he could do any better write me my last check. Otherwise he could get out of my hair, and stay out of my hair. I understood what my job was and I was doing it the best way I knew how, pointing out that when I walked in the door, I had replaced 5 other "engineers" who combined stood around open mouthed while watching me fix stuff they had been boxing up and sending it to the factory shop to get fixed. Effectively they were shipping clerks. Since there wasn't anything left for them to do, 3 of them resigned the first week, the old Chief stayed around for 2 at my request just to make sure I knew where all the light switches were & the last one was about a month leaving. I ran that tv station for the next 10 years alone but asking for muscle when I needed some. Because the transmitter wasn't remote controlled, I had 4 'operators' at not much more than minimum wage. That was my 'engineering' dept. But that sort of pressure, largely self-inflicted as I wasn't home for dinner till after 8 way too many nights, was the main reason I didn't stick it out till I was 68 & change to get the bigger SS check. I don't think I would have made it. :( I had a few things I wanted to do, and linuxcnc is one of them, hopefully getting some of them done before I fall over. Fishing is another, but thats a waste in WV, no Trout & even Walleye's are very hard to come by in these here warmer water parts. But he doesn't charge you for the time you spend fishing, so I ought to have 5 years credit just for that. :) Part of the secret is always having something to do with my hands and brain. :) The rest of the secret of course is: Faster horses, Younger women, Older whiskey, and more money. :) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
