|Optical PC-bus expansion|
In 1993, Tokyo Research Laboratory developed a technology for extending the I/O buses of personal computers.
A PC bus is extended by means of an optical fiber, preserving full compatibility with ISA-bus or MicroChannel.
Ordinary PC add-in cards can be placed several meters from a PC, to which they are connected via the optical link.
We also designed a PCI bus version of the optical PC bus extension in 1994.
