I develop software at work and have crafting as a hobby.

 

I like to use the tools you see below in a combination with traditional wood working to create new pieces of art.

 

I also use electronics in my creations to get interesting results, sometimes combined with a microprocessor and software.

Computer History

This section show the computers I have programmed.

Texas TI57, 1980
Texas TI57, 1980

This was the first programmable device I used. I bought it myself for hard earned money. I used it for solving equations numerically while I struggled with the symbolic solution. When I found a solution then I could compare it with the numeric solution as a quality check. The calculator used about 10 minutes I think for the calculation.

Apple Europlus II, 1980
Apple Europlus II, 1980

This was the first real computer I programmed. The one I used had only a cassette player for storing programs and a kind of tinn foil printer using heat to produce print. We had a star wars game using pads to control x fighters shooting each other. The first real program I made was a hang glider graphical game.It was programmed in Basic and it was a real challenge to get it running fast enough.

When I was in the army I used this computer briefly for programming exercises in computer courses. The programming language was Basic.

When starting my higher education in 1983 at Kongsberg University College, we used a HP 3000 computer with various terminals to program in pascal. We had one graphical terminal capable of displaying graphics and I made a three dimensional maze game where you could walk around a random maze to find the exit. The programming language we used was Pascal.

I borrowed this Norwegian produced computer for short period of time and used it for some small programs.

Seequa Chameleon, 1984

I have been flying hang gliders for some years when I got a request for making a computer program to keep track of all results in the 1984 open european hang gliding championship. I made the program on this computer using JRT pascal. The computer was quite special in that it had both a Z80 and a 8088 microprocessor. It could run both MS-DOS and CP/M. It also had the nice feature that it rebooted if you was a little bit static and produced a small spark.
