My favourite hobby  with which I spend most of my free time  are of course my computers. I have collected quite a lot in the meantime. The most of them are IBM, but also a few prehistoric homecomputers.

Some machines exist in several different versions and conditions. I lost the control about my stock in the meantime, since a lot machine have been deactivated and are stored in a storage in another house. Therefore it is a bit complicated to tell, what I have exactly. Some of the machines are lended to friends and relations.
Some of the machines are still used for daily purposes. The 8088 / 8086 and 80286machines have however been retired  except the Toshiba T3200, which contains my Eprom Burner card.
For the MCA & PS/2 Enthusiasts I run a particular MCAspecific page. There you could find a lot tips, tricks and instructions for little reworks and  of course  a hell of Adapter Description Files (ADFs). Because I work with MCAPS/2 since 1987 I had the occasion to collect quite a lot stuff.
In addition I regularly check into the Newsgroup comp.sys.ibm.ps2.hardware, post my results there and answer questions about any kind of problems with the old PS/2machines.
