Does anyone have one of these in running (reliable) condition? I found a lot of documentation of an attempt to run one at Digibarn for the 30th anniversary of the Alto, which did not appear to be successful, and that got me to wondering if there was a working one anywhere. Nick would probably be advised to look at that documentation as well as other web pages I've sent him as far as planning what he tries to do with his system. It appears there were maybe 3 sets of spares for the Digibarn one (just morning light to darkness trying to get it working before giving up. I am not familiar with the person who was trying the bringup, but assuming he was one familiar with the Alto and with all those resources, it says a lot about getting one of these w/o extensive knowledge (true of any vintage system) and trying to bring it up. It's the nature of some designs they always did something you could nurse along to running, and some, perhaps like the Alto may be pumpkins until a lot of things work, and it can be very difficult to figure out if you are damaging them along the course of the effort (2 steps forward 3 back). http://www.digibarn.com/collections/systems/xerox-alto/
