One thing that I've tried to maintain in the hardware design is
flexibility. There will be two boards. Once board will contain all of
the main logic (FPGA, uC, IDE interface, etc). The daughter board will
have the interface adapter (ie massbus trancievers). By creating other
daughter boards (I'm planning a Unibus one too) and loading different
code into the FPGA and uC, it should be able to emulate almost any type
of disk device (maybe tapes too...but that'll be later).
