0 - My first introduction to computers was in the late 70's at the university where my dad worked. They had a room full of teletype terminals which were connected to a big computer in some other room. They had a user account that would run games if it wasn't too busy. We played a text game called
"Star Trek". It would print out what the surrounding quadrants had in them, and you typed in your commands. We used a lot of yellow continuous feed paper. We made up for it by recycling the paper-punch programming cards for craft projects.
1 - In grade school, they had a
Tandy TRS-80. The designers of the "Trash-80", as it became to known, thought they could sell 50,000 units. The company decided to only make 3500 because they figured if they couldn't sell them, they would use them themselves. They eventually sold 250,000 units. I programed the TRS-80 to show a WWII submarine with waves moving past it. How is that for foreshadowing?
10 - My first computer was a
Sincair XZ-81. I paid $99 for a kit, but they ran out of kits, so they sent me one assembled, which would have cost $149, for the same price. Amazingly, you can still buy a
new kit for $200. It had 1 kilobyte ram and ran at 3.5 MHz. It saved and loaded programs on a tape recorder. I programed it to show balls bouncing according to the effects of gravity, and simple orbital paths.
11 - It is a good thing they sent the XZ-81 assembled, because latter I paid $300 for a microcomputer kit, which, when I was done soldering it together, let the magic smoke out of the power supply and I couldn't get it to work. I was too embarrassed to ask anyone for help, so I threw it in the trash. I delivered a lot of papers for that experience.
100 - In highschool they had about a dozen
Apple IIs. They were all connected to a thing called a "hard drive" which could store and retrieve 5 megabytes of data. Man that was a lot. My project was a program where you could save text messages which could be retrieved later by other users, kind of like "electronic mail". I don't think I ever got it fully working, but it was a neat idea.
101 - My next computer, which luckily wasn't available as a kit, was a
Radio Shack color computer. I think I paid $399 for it. You can get one on
Ebay now for $23 + shipping. It came with 4 kilobytes of ram. I got bored with programing in Basic because it was so slow. I taught myself assembly language and made a counter than ran so fast the first digit was a blur. Man that was fast. I later upgraded it to 16 kilobytes because my programs were getting larger.
110 - When I was in early in my Navy career, I bought a
Commodore 64. They retailed for $595, and are now available on Ebay for about the cost of shipping. It was the first computer I owned with a "disk drive". The external drive was almost as big as the computer itself. I think I mainly played games on it. I once got so mad when playing a game that I took the disk out and cut it up on the spot. Solved that problem.
111 - When I was stationed in Hawaii, I bought my first laptop, a Toshiba T1000se. I think I payed well over $1000 for it. I don't see any listed on Ebay right now. It had 4 megabytes of memory and ran at a blazing 9.54 MHz and had MS DOS 3.11 in ROM so it booted quickly. I mainly used it to play submarine simulation games like
Silent Serice II and
688 Attack Sub, which is kind of crazy considering I was living on a sub at the time. Toshiba latter sold some
CNC technology to the USSR which allowed them to make advanced submarine propellers. There was some kind of boycott, and I was a bit embarrassed about owning it. I ended up selling it for $50, which is what it cost me to replace the battery to get it ready to sell.
There you go. Eight bits (a byte, get it?). Catch the
binary numbering? I didn't even make it into the Windows era. Oh well, tune in latter and I'll tell you about the hand-me-down
3-GHz, dual-CPU Xeon, workstation they gave me to run Linux on at work. Talk about fast . . .
Now I'm thinking about going back for another try at the ZX-81 kit. Maybe I can keep the magic smoke in this time.
On the left are the "building blocks". In the middle are the program steps. On the right is the output. You can actually change the program while it is running, and see the immediate results. Well, it impresses me anyway.
But seriously, take a look at their outfits and the flag on the wall (click on it to get a full size version). This is supposed to be on 2nd street in Corvallis. I don't think the building still exists.
Here is one of a new model bicycle. Note the lack of brakes and chain. They must be just checking out the handling. It has got nice lines, but I doubt that goofy looking handlebar setup will make it into production.
This image is inverted. You can see the building I work in, framed by trees!
Third and last trip out to see the web. Self portrait a-la-web-dew! I wish I had more time and a better camera!
I haven't had a lot of time to work on the bike, so it is progressing rather slowly. I read an interview with the original designer, and he said they were putting 80 hours into a completed bike. Now I know why they are so dang expensive! I'll probably have twice that in for half as good a bike. At least I can say I built my own bike.
I've about got the frame completed, minus paint. I just put in the brake bridges and relocated the cantilever pivots. Click on the top picture to get a better look at my wicked good brazing skills. It'll look better painted, trust me. I'm going to prime it to keep it from rusting, and build it up so I can ride. I've got to finish it before the rains set in so Sweet Polly Purebread can have her garage back!

Actually, that is as a computer modeling technician. What does that mean? You can use a computer to model the characteristics (physical, thermal, electrical, fluidics) of just about anything. And it is cheaper and faster than building and testing the real deal. So, that makes it possible to test, refine, and narrow down design possibilities before building physical models to test. It seems everything at HP is now "faster, lighter, cheaper". Well, not lighter, unless you are talking about head count. In the recent round of restructuring we just sweated through, most groups lost positions, while the computer simulation group gained positions, me being one of them. I hope that is a good sign.
I dare you to watch at least the first ten minutes of Six-String Samurai. It is on Netflix "Watch instantly". It is rated PG-13 for "martial arts and swordfight violence".
The quickest way to spot a home-make recumbent is the seat. A lot of times they are made of wood with foam padding, or have a "lawn chair" look. I decided to build a version called a "sling seat" because it looked good, and more importantly, looked comfortable.
The frame is made from electrical conduit tubing, which is available in several sizes at most hardware stores. The only drawback is a zinc coating which needs to be removed before heating since it gives off toxic gas. Other than that, it is pretty easy to bend and work with. The plans on the web actually give full size printouts, which make it easy to get the right fit.
The covering is made of a material called Phifertex. It is a vinyl covered nylon mesh, and is designed for outdoor furniture. It is extremely strong and rip resistant. Its main advantage is allowing sweat to evaporate from your back while you are riding.
Its a new season of shows on TV. What are you guys watching?
