I recently ran across a manual and disks for a PC networking product called ViaNet. It was marketed by Western Digital and targeted toward Arcnet, although it looks like it worked with Ethernet and other topologies. There isn't a lot of info out there about it but there are a few pieces in the old trade mags on Google Books. It was peer-to-peer between PCs, but there was also a UNIX host server product for it.
Anyone ever worked with it? I scanned the manuals and posted them here: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/WesternDigital And the disk images are here: http://nocarrier.net/archive/floppy_images/PC/WesternDigital/ -j
