{A2Mbps and E2Mbps MC Adapters}
{Standard Bus and Micro Channel}
LANtastic A2Mbps and E2Mbps MC adapters are the perfect way to
economically network small or medium-sized businesses with IBM PC
or Micro Channel compatible computers.
Both Micro Channel Architecture and Industry Standard
Architecture (ISA) adapters include a 10Mhz coprocessor, and 32K
of on-board dual-ported RAM. Each 2Mbps adapter also includes
software-selectable IRQ and RAMBASE address settings.
Artisoft's implementation of the NetBIOS standard is loaded into
and executed within the adapter. This plunges the NetBIOS draw on
a PC's base RAM down to just 2K and off-loads network processing
onto the adapter. The cards are easy to install and use
inexpensive dual-twisted pair cable.
LANtastic A2Mbps and E2Mbps MC adapters drive cable lengths of up
to 1500 feet per network with Artisoft cable, up to 300 feet with
AT&T telephone-grade cable, and will handle 32 nodes per segment.
