    Why "Bunker of DOOM"? Simple.. easy to remember, and appropriate since many of the technologies practiced by those who enter these portals were long ago doomed in the face of so-called modern advancements (read -cheaper manufacturing and higher efficiency at the terrible cost of tangible craftsmanship). Certainly alot of very fine craftsmanship, the best, has gone into the integrated circuits inside your modern appliances as well as their stylish exteriors, but it's no longer tangible to the user. There's nothing personal or hand-finished. You can't see it, you can't feel it, and if you want to change something about the way it werks, well.. you're out of luck.
    So, many of us choose to work with the technologies and methods of times past for our own enjoyment. Today can be "the good old days", where "American Craftsmanship" means something, if you will only build something for yourself with your own hands. Imagine the satisfaction from that. Perhaps you already do this, but not yet with electronics. Welcome to a new world. God Bless America, and good night.

    Site User Availability Notice:


    Schedule of maximum guest availability:.
    2AM-4PM Monday-Friday
    3AM-8AM Saturday-Sunday
    Time zone is GMT-6

    Here's how it works:
    The outgoing internet data rate is 600K Bits (about 15 times faster than a 38.8 "dial-up" modem). Due to this limitation a condition may rarely occur, especially when a guest is using an automatic program to perform multiple simultaneous downloads (such as downloading an entire tube mnaual 10 pages at a time), that our own communications become inconveniently delayed.

    The way it works, for those that don't know, is that in order to get mail or to surf a website, the desktop computer must first send out a request to the server on the internet. When the server receives the request, it sends the material.

    There are two 'pipes' through which the information flows. One is going out from the computer to the internet, and one is coming back from the internet to the computer. If the outgoing 'pipe' is full (because the webserver here is sending alot of data to someone on the internet), requests from the other computers here can't get out easily, and therefore the other computers get no response from the internet and will show an error or timeout.

    This very rarely occurring condition also hampers other guests on the internet who have as much privelege to the material stored here as anyone else. It's not in any way a limitation of the server, but merely a question of $Paid Bandwidth$.

    Should this this rarely occurring condition occur, and we need to use 'the internet' right then, we may even more rarely elect to temporarily reduce or stop your data transfer rate from our machines while we use the bandwidth, and then make it available once we are done. Usually we will wait a while to see if we can get a quadword in edgewise before we do that.

    If the site stops or 'disappears' while you are downloading or mass-downloading, don't take it personally, you are welcome to the files. Please check back later, it won't be for long. Most automated downloading software is smart enough to continue after being interrupted. These programs can also be set to 'politely' open only one or two simultaneous connections and that will reduce the probability of our interrupting a guest session. That would be nice. If you want to download files 10 at a time, do it during the hours posted above. Thank you for your kind understanding.
