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 THIS WEBSITE!

The main focus of this website are the CP/M Kaypro's, North Star Horizon, IMSAI 8080, Altair (Duino) and the old 8 inch floppy disk drives such as the Shugart 860 und 851, the Misubishi M2896-63 or the NEC 1165.

My other projects are the IBM 5150, 5160, 5162 & 5170. You will also find a lot of information about: CompatiCard I & IV, UniForm(-PC), UniDOS, 22Disk, Kermit, Backpack, RC2014, ZETA V2, BabyBlue, Deluxe Option Board, KryoFlux, FLUXTEEN, Greaseweazle ...

At the beginning of 2023, I still assumed that the N* Horizon would remain my only S-100 computer, so I mentioned the S-100 boards there as well. Meanwhile it is October 2023 and I have three S-100 computers (N* Horizon, IMSAI, Sol-20) and also many S-100 boards. Maybe, maybe not, I will list the S-100 boards one by one sometime. With the Cromemco 8K Bytesaver I tried it.

Long story short, my S-100 cards can be found at the respective computers.
