Unibus disk controller with modern storage

[shadoooo]

Hello Dave,
exactly!
But in place of a plain FPGA, nowadays I would choose a FPGA-ARM board, 
for example
the ZedBoard MicroZed or the Myirtech Z-turn, both of them have a Zynq 
onboard,
and they can run linux for the software side and programmable logic for 
the interface side.
Very nice and flexible.

For the development, I'm trying to figure if an hybrid QBUS / UNIBUS 
solution is possible.
Of course one have to switch some jumper to avoid conflicts, but hey, in 
the end you
would have a true universal board.

What kind of bus transceivers did you used for the QSIC, specially 
because you have
to go from 5V open-drain logic to 3.3V logic?

Thanks
Andrea
