I have a indigo that is not getting much use. I believe it has the R4000 with the better power supply, and maxed out ram.(whatever that may be, i want to say 192 Mb, but i coud be mistaken, i can fire it up and verify if needed) I have not used it much. Prom battery is dead, i used to jump it with a AAA battery temporally to get past a Time error at startup, but never got around to soldering a proper battery into it. It should have the maxed out memory, as well as the keyboard and mouse to go along with it. I am in the process of paying off 2 SGI onyx 2's, if the indigo with the keyboard and mouse would be of interest, i can sell it to you to put money twords my Onyx fund. --Devin
