LCM have atleast one 11/70 running. Although they are not really doing anything fun on it. I hope to maybe help them with that next time I'm there. I can't remember seeing any 11/45 running, but I'm pretty sure there are some in their storage if nothing else... I'm not going to try dragging a lot of documentation from Sweden to Seattle, though (I'm not even in Sweden myself lots of the time). On the other hand, I know they have plenty of documentation, so I would hope they (and/or CHM) already have most of it. > Since their goal is to have ancient computers actually > running, they are certainly interested in having all the > documents (even if you can't get the wood, as Warren might > remark at this point), including full engineering drawings. > > It's also a neat place to visit if you have some free time in > Seattle.

It is a fun place, and I could see myself working there, if I just had the right offer. Don't expect that to happen, though... I'll be there for different reasons in about a month from now. But my weekends are free... :-) Johnny
