I am in computers since I was 13 years old. I remember that my first machine was a VC20 in the "secondary" (main school) here in Germany. We started then with 3 Apple IIe, it was so cool, it came with two 5:15 "floppy. When i went to the next school (vocational school) i got in touch with my first Mac Classic II, and with Commodore CBM8000. A friend of mine sold me his laser then 210, that was such a great machine, i loved it a lot (sadly i do not have it anymore 
). This time i started to fall in love with Atari. I got my first Atari 400th Man i will never forgett it! AS soon as the Atari800XL came out i got it and was totally impressed. We wrote a cool adventure and had a lot of fun.
That reminds me to a funny story. My uncle and me bought a magazine, they had the listing for Donkey Kong in. We wrote the whole night. And i wrote "Run" 
It did not start! We had no chance to get back! All was lost Well, as we were motivated, we did it again. Once all done what we did not want make the mistake twice. All written and what we said: YEAH save only now and then run so we wrote LOAD and then enter. Our face went white! All was gone again HAHA. Man what a time
My uncle did not like the Atari way to much and made the decision to go with a C64. He wrote some very cool games and sold them to the C64 Magazine. I wanted to stay with Atari. Bought myself a datasette and later a floppy drive. After a while they announced the Atari 520ST. WOW what a machine! The design was so cool and all fit together. So i went to Massa and bought it with the screen (monochrome) and a printer. I used it for quite a while and then i saw the new 1040ST. With the floppy to build and nice features. It was a must to update the machine. I wrote a nice car manager game for it and loved it a lot.
Then i was sitting at work and read a newspaper. HOT Phillips offered at a 8086 computer. 640KB RAM, 3.5 "floppy disk (720KB), 10MB HDD! WOW how awesome! and a screen and mouse. That computer looked so cool, really. It was my first step into the x86 world. After that i had a lot of strange computers and upgraded all the time. From 10 to 20MB HDD, from 720KB to 1.44MB from 640KB to 1MB ... it went up and up
When you are into computers for quite a while, in my case 24 years now, you see a lot of things coming up I bought a lot of equipment every now and then, tested a lot of things ... Over the time i got rid of the most of that equipment. Unfortunately i must admit! But over the time was still some stuff laying around on my place and i kept it. As you know i have that huge house with a lot of space. So i made the decision to start my own small computer museum. I started to collect stuff together. Here is a small list of things:

If you see some old home computer around i would love it when you let me know
