Thanks all for the answers. My limitation is about supplying the card, not signaling. I found that there is 5V wired but with limited current. Maximum is about 100mA, now has anybody incidentally any experience about power consumption? Shouldn't be too much, I guess. At least it needs no fan;-) Thank you, -Harry > > However, you actually meant that you need a card for a "3V3 PCI slot", > that's a different matter altogether (a "3V3 PCI slot" uses 3V3 signalling > levels, but still has all the normal power supplies). > > I have found two PCI cards that will go in a 3V PCI slot (both > dual-voltage cards, since the majority of PCs have 5V slots and so there's > no market for 3V-only cards). > > One is the AVM Fritz!Card PCI version 2 (version 1 is 5V-only), now > supported by the ifpi2 driver. > > The other is the ASUS ISDNLink 128K - again, this comes in various > different versions, and only the more recent version (P-IN-ST-D2) is > dual-voltage.
