Sorry, ambiguous, nothing wrong with the Z8400 or the Z80 in general; fine
architecture; I was just contrasting the more "ambiguous" design of a card
like that which is under discussion, to something that's just got an NCR
5380 or similar on it, that just jumps out at you and yells "SCSI!"
Best,

That this one turned out to be SCSI with the

What's strange about a Z8400? That's a normal Z80 CPU. If there are
two additional digits after "8400", that's the rated speed in MHz, as
opposed to the older alpha scheme (Z80 = 2.5 MHz, Z80A = 4 MHz, Z80B =
6 MHz, Z80H = 8 MHz).
