Microtek Z3i. A good fit?

[zipper]

The Z3i does not have Zorro III, it is only a ZorroII Busboard, if you have an A4000 CPU attached then you can access the fast ZorroII mode supported by a few cards (I think maybe the CV64/3D) but it's still not Zorro III

Huh huh...http://amiga.resource.cx/exp/search.pl?product=Micronik+A1200+Z-3i+&company=&amiga=&intf=&mid=&base=dec&pid=
...but the ZorroIII implementation is clearly slower than the original.
