RE: More on 66Mhz & Universal keyed card test systems.
I have heard the argument that since there are not that many
3.3V or universal cards on the market, the slots need to be
designed with 5V keying (regardless of actual signalling levels).
On the other hand, because there are no 3.3V-keyed slots
available, why would anybody produce cards for them?
How do we get around this chicken-and-egg problem, how can
the industry ever move to 3.3V cards?
I would be interested in hearing your opinions about when
universally keyed or 3.3V expansion cards are expected to
make a breakthrough on the market.
