The ZX340 series of multiport PCI adapters was discontinued in 1998. It was replaced by the ZX340Q series adapters (note the 'Q' suffix, identifying the current products).The discontinued ZX340 series adapters are no longer available.

The old ZX340 series employed the Intel/DEC 21140 MAC chip, which was discontinued by Intel. The new ZX340Q series uses Intel's 21143 MAC chips which offer improved performance and built-in 10/100 Mbps speed autonegotiation.

The current ZX340Q series product line includes the following 10/100 Mbps Ethernet adapters which provide the same, or better, functionality as their earlier 'non-Q' counterparts:

The current ZX340Q product line offers an even greater range of standard driver and RAINlink driver compatibility. However, Macintosh users please note that none of the current ZX340Q series adapters support Mac OS, Mac OS X, or Mac OS X Server.
