About Miguel Dutra

Hello! My name is Miguel Dutra and this is my tribute website to an old Brazilian computer called CP500.

When I created this website I had great plans for it, but then I realized that, in order to make everything I had in mind, I would spend much more time than I wanted to. So, I decided to simplify.

What you are going to find here is, basically, part of my past. I really enjoyed programming computers and one of the first ones that I had contact with was a CP500 from Prologica. The CP500 was sold as a professional machine and its computing power was just a fraction of what you can get from a simple mobile phone nowadays. Despite that, it enchanted me. One page of this website is dedicated to that wonderful machine.

Another page is dedicated to programming, a hobby that I keep till these days. Since 2009 I am working on a program to manipulate files of CP500 and TRS-80 virtual floppy disks that you can find on the Internet. Programming is my hobby since I was 13 and it is also an escape when I'm tired of everything else.

In 1990, when I was 16, I published an article in the Brazilian magazine Micro Sistemas, which was very popular among the computer users at the time. Computer viruses were a hot topic and I was really fascinated by them too, so I sent to the magazine a program written in Turbo BASIC whose purpose was to detect the virus Friday 13th in PC files.

A few months later, in that same year, I sent a more elaborated article which turned up becoming the cover story of that month's issue and also subject of the editorial letter. I got so proud! It was a triple vaccine developed in Turbo Pascal to find and remove the most common viruses at the time: Friday 13th, Stoned and Ping Pong. After those, I created several other programs yet more interesting and elaborated, many of them related to the security field. Looking back now I regret for not having them published.
