A New FDC Board for S-100 Systems |

For people that may be interested in building a new S-100 Floppy disk
controller (FDC) board that can be configured to work with most 8 and 5 (soft sectored) disks I have designed and built a new Z80 based Western Digital 2793 FDC board. With Andrew's help (3 prototype boards later!) we now have a board that we are very happy with. With its own independent Z80 on board, it is completely command driven via 2 parallel ports (with strobe bits) to/from the S-100 bus. This makes writing BIOS'es for any operating system very simple and easy. For anybody that's interested in obtaining a bare board we will be ordering a batch real soon. Please see here for a more complete description. http://s100computers.com...s/ZFDC%20Board/ZFDC.htm Reply |
