Any Mac which does not provide termination power is 'picky'. Perhaps on your Mark 2 adapter, you might add a TP option.

Any Mac which does not provide internal SCSI termination will be 'picky' too.

The IIfx has its own termination design. It is close enough to SCSI 2 active termination for most devices to work seamlessly, but not all.

Assume that the Mac Plus, PowerBooks, Duos and docks, Pippin, IIfx, Quadra 700 (unusual dual bus) will be fussy. It might be easier to rephrase the question: Which Macs are not picky?
