- A few questions:
-
- - Presumably there is a card form-factor and connector defined for
- this standard. Could you say more about that?
-
- - Similarly, there is presumably an inter-box cable and connector
- defined, or will be. Comments? Incidentally, are the signals
- differential-drive, or do we have to worry about common-mode noise
- and grounding? And do peripheral devices get to draw power from
- the big box over this interface?
-
- - Given that Microsoft's NT supports multiprocessors (16 CPUs have
- been demonstrated) and Compaq's position as a high-end vendor for
- Microsoft-compatible iron, I'm suprised that Compaq is proposing an
- I/O architecture that is single-CPU oriented. Why?
-
- - Another likely multiprocessor application appears in laptop-type
- "docking stations", where the laptop plugs into a desktop machine.
- Is this bus suitable for that application?
