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 private and non-commercial website has the purpose of my personal diary and technical documentation.
I do not use advertising, tracking or cookies on my website.

Why is this website still as structured as it was 20+ 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! You can also view this website with the old Arachne web browser on an IBM PC, XT or AT.
