I found an RS/6k 7009/C20 256/4gb for very little money. Is this machine worth it? AFAIK, this is a PPC 604/120 microchannel machine. It has a 10/100 NIC, and some sort of graphic card with a 13W3 connector. Is the pinout of this card known? Does this machine take PS/2 periperals? Thanks for any and all help?
