So I Got This Old Sun

Hoping to bring some knowledge out of the woodwork here...I have acquired what is, in any case, quite a relic, but I suspect there is much more to learn about it: http://silent700.blogspot.com/2014/06/leads-always-follow-them.html In short, I stumbled upon a Sun-1. It's the rackmount version, the 1/150, but it has a strange model name on the ID plate which appears to be "RM-CC" or "RM-0C." It has a very early serial number but I can't determine if that was its first number or the result of an upgrade or refurb. It appears to contain a Sun-2 CPU board so, according to what I've read, should be ID'd as a 1/150U. I've read nothing about re-assigning a serial, however. I was told that Sun-1 serial numbers began at 013, due to there being 12 employees at the time. Again, I have no idea if this machine's serial number is original or not. It was sold to the University of Chicago, who I believe were among the first purchasers of Sun products. They are said to still have S/N 13 (in theory the "first" Sun made) in their posession but I have no first-hand knowledge. I am supposed to be put in touch with the original curator of this machine, from which I hope to learn a lot more about its history. For now, enjoy the pics and please share whatever info you may have... - jht
