@611F.ADF NetWorth, Inc. - EtherNext/MC Network Adapter
Isn't it great when companies totally deny the existence of the very item you happen to have? NetWorth was swallowed up by Compaq. To date I've found no mention of this adapter on the HP or Compaq websites. I can find references to other NetWorth products, but not this one. I'm of the belief that NetWorth's later products came to be the Compaq Netelligent line of products.

I'm not entirely certain that my LED mapping above is correct. I am pretty sure that the DS2,3 mapping is correct with COL(lision) being the yellow LED. DS1 has been loosely extrapolated from the DP8390 data sheet. I know that the red LED (reverse polarity on UTP cable) is correct.
With the diagnostic LEDs on this adapter, you could use it to perform some quick checks on network segments.
At one time NetWorth probably provided owners of this card with some drivers for common network operating systems and applications. I can't find them.
As of this writing, I'm running this card under Windows NT Workstation 3.51 Service Pack 5 with a Netware NE2000 driver. This works although the card tends to "choke out" on larger data transfers. The NE2000 driver is also probably not capable of using the DP83902 IC to its fullest extent.
