    87 Octane Computer

    Well, shucks, I just spent New Years Eve and New Years day, sitting around counting raindrops and floods and road closures. We have been marooned for a few days, with an short break this morning that enabled me to get to a gas station to replenish the fuel supply for our generator. No electrical power for a day and a half. It gets really dark out here in the woods.

    Now that I seem to have enough gas to keep the generator functioning for another couple of days, I thought I would see how my PC runs on 87 Octane. First time I tried it on the generator. Seems okay. But I will exit really soon.

    Generators can put out square waves, with harmonics that can get into yor audio. If it puts out sine waves with a good regulator you should be fine. I tried to run my B3 on an unregulated generator once for a Big Sur party. Had to hire a teen to stand over the generator and keep the engine speed as constant as possible, even then I felt like I was onboard a rolling ship - random pitch variance by 1/2 steps.

    Your sequencer clock may also not be happy...

    HAHAHAHAHA!!!
    That sounds like fun on the Hammond!! What happened? Was it the current slowing down and speeding up the tone wheel or something?

    I am not using the sound system at all. Just a quick on line visit, check flood level and slide conditions. I have no control on the geneator. It is locked at (theoretically) constant speed. It is only a few years old, not much used till now. Only 3KW, but it is doing an acceptable job, and sure starts easy!.

    For the life of me, I can't find a manufacturer or model number on the one I have (think the label blew off when we got hit by lightning a while back); but some of the better backup power supplies have both voltage leveling and wave shaping (as well as sophisticated clamping and protection)... might not be a bad idea to look into that.

    Took a direct hit a year ago, here; the power goes on and off apparently at whim; and my generator [came off a submarine] is probably older and crankier than either of us: so far, so lucky.

    Well, my generator did not come off a submarine, but I remember a communications station where we had a generator driven by a submarine engine.

    Sounds like your power system is as flakey as here. We have more power failures here than I have seen anywhere in the world, and that covers some territiory and some interesting conditions.

    I think our best one was a few years back, when we had an ice storm that deposited, literally, 2+ inches of solid ice on everything. We were down close to a week.

    It was fascinating. The power system up here was in complete wreckage, utterly beyond repair.

    The power company dug up some half-tracks somewhere -- nothing else would go up the mountain. They had two guys on the side of a couple of them with enormous chain saws, chopping the poles off ten feet off the ground and letting the whole shebang fall.

    Right behind them was a pole-hole digger and a crew dropping new poles; and behind them huge reel truck flatbeds dragged by more half-tracks and a wiring crew of a dozen workers hanging copper... and behind them, cable and phone riggers.

    Amazingly, when they finally got at it, they rebuilt something like five miles of line in just a few days.
