Perhaps the opensource decnet kit may be portable. I know there's a DECNet kit for Linux out there somewhere. Not sure about anything else. Nothing crops up on a quick Google search that isn't dated early 90s. I wasn't aware that AIX was so hobbyist friendly. The hardware is vey unfamiliar for me though. The hardware is generally pretty unique (save for it's similarity in patches to PPC Macs) - all IBM stuff generally is. The OS is proprietary but you can pick up media kits off eBay for not a lot. Also IBM documentation, certainly for RS/6000 / pSeries hardware and AIX, is readily available online without even needing a login. -- Mark Benson My Blog: <http://markbenson.org/blog> Follow me on Twitter: http://twitter.com/mdbenson "Never send a human to do a machine's job..."
