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.

PCBs on their way! They should be here mid April or so.

Thanks and have a nice day!
