SGI 4D/220s

<http://www.xmission.com/~legalize/vintage/images/4D-220-1.jpg> <http://www.xmission.com/~legalize/vintage/images/4D-220-2.jpg> So you bought those twin tower systems. We were all crying over them. Those are Twin Tower 4D systems as you can already see and they are not the most powerful things out there as they are pretty old. They should be able to run Irix 4.0.5 but that is it and I don't know much about Irix software older than version 5.3 so you better hope that there are some GL demos installed. In all honesty I recommend you go talk to the folks over at http://www.nekochan.net as they are the last people on the net really to tame these old beasts. I also recommend http://www.martnet.com/~bobd/sgi/4dfaq.html as it contains a nice FAQ and tells you how to make a serial terminal cable adapter which is essential for any SGI system. John.
