Powered by a socketed 12MHz 16-bit AMD 80C186 CPU, two 128Kbit 27C128 UV EPROMs
with even-odd bytes of microcode and four 8Kx8 SRAMs

There's also an Intel 82586 Ethernet coprocessor, 3Com PHY and bus interface logic, etc.

Connects using a thick coaxial (AUI, DB15F connector) or thin coaxial (BNC, RG-58A/U 50 ohm) cable,
 though there are various transceivers to RJ-45 twisted pair available on the market

Driver support includes Windows 95 and NT, OS/2, Linux, various BSD, etc.
