5 AristotlePagaltzis 2
18 AristotlePagaltzis 3 Written by [Cisco] for use in their networking devices, such as routers.

10
11 Some of these devices (most famously the [WRT54G]) run a version of Linux,
12 for which Linksys has made the source code available on their website.

16 Cisco 7xx:
17
18 A Combinet product that was relabelled when Cisco acquired the company.

43
