These LAN boards powerfully support high-speed communication on PCs
by being installed on PC extension slot.
Loaded with CPU, ROM, RAM, and TCP/IP communications control software,
they operate high-speed TCP/IP communication independently from major
program.
Each type has two versions: ISA bus for DOS/V, and C bus for PC98.
|
 |
Loaded with V53A(16MHz) CPU, 64-512KB
of ROM, an FIFO unit with built in 64KB memory, 1MB of local
RAM, and 10BASE-T/10BASE-5 Ethernet LAN interface. |
|
By being installed on PC extension
slot, they operate high-speed communication independently from
major program. |
|
Multiple boards can be installed
on one PC's extension slots. |
|
Multiplexing and multitask program
are possible. |
