You must of blinked.

The ET532 - Ethernet 532 is a plug in card for the PC532. It connects via
the expansion SCSI bus. It also has a 50 pin scsi header and power supply
connector for stand alone use (i.e. via a different SCSI based machine).

32GX32/32532-20MHz
1 or 4 Mbytes of DRAM (via fast page 256Kx4 or 1Mx4 dips)
1 Boot EPROM
1 1024bit EEPROM (for ethernet address etc)
It has 16 serial ports (rs232 buffers are on a daughter card).
1 DP8490 SCSI interface
1 8 bit expansion connector (for other stuff)
1 Ethernet interface using the NSC DP8390 etc chipset. Supports thick
 ethernet and cheapernet (thin coax).

The board is designed and routed. It has never been built. All that is
required is a reasonable number of people to want it (reduce the PCB NRE etc)
and it is ready to fab. The design is based upon the PC532 and an ethernet
design I've already done - so even though it would be a prototype run I have
very high confidence in the design. Maybe a cut and jump or two though...
