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.
