About this Site

The main focus of this website are the old floppy drives such as the Shugart 860 und 851, the Misubishi M2896-63 or the NEC 1165 (all 8 inch drives).

My other projects are the IBM PC/XT 5150 under DOS and CP/M-86, the Kaypro 10 and generally the data transfer between all my systems (DOS, CP/M, CP/M-86). Be it via floppy, CD or cable. Some keywords: CompatiCard, UniForm-PC, UniDOS, Kermit, Backpack, Megamate 2.8 ...

This website has also mainly the purpose of my technical diary or documentation. With time, I forget a lot of things. I just don't get younger ;-).

Special note on downloads: If downloads are offered on this website, the download is always at the user's own risk. Although all downloadable files were checked with a current antivirus program and current virus signatures at the time the respective website was created, the operator does not guarantee the actual absence of viruses!
Special note on advertising blockers: On these pages a few pictures (screenshots) from old advertising are shown. And what should I say, my advertising blocker works (-> Cross-site-tracker)! So, if this should also be the case with you, then it is because of it! I intentional do not use advertising or trackering on my sides.

Why is this website still as structured as it was 10+ years ago? Because that is the way it should be for Retro Computing. Wordpress and Co. wouldn't be a problem for me, but I don't like it! But you can follow me on Twitter.

This site is also usable on mobile devices!
