I am in computers since i was 13 years old. I remember that my first machine was a VC20 in the “Hauptschule” (mainschool) 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 (Berufsschule) i got in touch with my first Mac Classic II and with Commodore CBM8000. A friend of mine sold me then his Laser 210, that was such a great machine, i loved it a lot (sadly i don’t have it anymore 
). This time i started to fall in love with Atari. I got my first Atari 400. 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 didn’t start! We had no chance to get back! All was lost Well, motivated as we were, we did it again. Once all was done we didn’t want make the mistake twice. All was written and we said: YEAH now only save and then run so we wrote L O A D and then Enter. Our face went white!! All was gone again HAHA. Man what a time
My uncle didn’t 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 build in 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. Phillips offered at HOT a 8086 Computer. 640KB Ram, 3.5″ Floppy (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 in computers for quite a while, in my case now 24 years, 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 some stuff still was 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:

Currently i increase the stuff i have here step by step.
Once i have a bit more time, i will build up a room for all the machines. The planing is around 150sqm (*9 in ft) to have enough space for it all.
If you see some old homecomputer around i would love it when you let me know
