I'm considering a DuoDock purchase from eBay, but I have a few questions.

First off: Did the all DuoDock IIs come with the 32kb cpu cache and FPU, or was it optional like the Dock I ?

Secondly: If you were to use a 270c in a Dock II or in a Dock I with FPU would it then be able to use both FPUs ?

Thirdly: Are there any difference between a II and a Plus other than the plus not having FPU and cache ?

Thanks in advance,

Ted
