This page is about my old computers and some new ones with an oldish style. Some I’ve bought, others where given to me and some are built by myself. Because peripheral devices and software where also part of the old computer technology, you can find them here as well.

I started this page to give my self an overview of what I collected, repaired and archived. There were so many pictures and PDF files with information about old computers and computer chips on my harddisk, all just loosely sorted and packed in folders. So I just wanted to make them a little bit more organized. If you find this collection usefull too, please feel free to use and share it.

As you can see, there is not much to see yet. I just started this page and I will bring it to more life in the next months. So stay patient…

Have fun!
