Kaj is on a mission! A mission to make software systems survive, allowing them to continue to give value to the company that has invested so much energy and money.
Kaj has been working with computers since he was 11 years old. He wished a Commodore 64 for Christmas, but as his parents had no idea about computers, they bought him a Commodore PC1 instead. It was able to offer 4 colours in a lousy resolution and wasn’t the gaming computer he wished for. It couldn’t do absolutely anything out of the box. Kaj went to the local library and found a book on programming, and that’s where it all started.
After a formal education as with a degree in Computer Science, Kaj went to work in the software development industry. Later he went freelance, and had a number of customers in various sectors. Throughout the years of creating software, Kaj did a lot of teaching – both as a software coach for individuals and teams, and by providing courses on various topics. Kaj has great sense of software quality and knows the tools and tricks that makes a piece of software sustainable for many years.
Kaj is married and has two boys, a cat and a rabbit.
Commodore released the PC1 in the mid 80’s. It featured a 4.77 mHz Intel 8088 processor. (Note that they included the decimals in the clock speed!. It’s not 4. It’s not 5. It is 4.77.
It was mounted with 512kb of memory and a 5,25″ floppy disk (360kb on each side) and was delivered with a MSDos 3.1 boot disk, which also had Microsoft’s own version of Basic, GWBasic.
The graphics adaptor was capable of showing CGA (4 coulurs in 300×200 pixels) and Hercules graphics (720*348 in monochrome).
