Well, yes, I'd make a PCB for it, I think the 1581 schematic is
available so it's just a matter of making a new pcb, using maybe SMD
parts where possible.
Of course, one would still need to provide 6502, 6526 and the FDC IC
(going by memory, so they might be different part numbers there).
These parts are getting not too common for my own taste. At one point,
I thought I would port the 1581 firmware to a more common CPU/parallel
port/FDC, but yes, having the sd2iec makes all this really a waste of

and where would we put the board and disk drive? No case?
