Harvard Mark I Manual On-Line

I haven't seen this announced here, so for those of you who don't read alt.folklore.computers, Al Kossow has made available a scanned copy of the Manual of Operation for the Harvard Mark I. It's at: http://www.spies.com/aek/pdf/harvard/MarkI_operMan_1946.pdf Be forewarned, however, it's big-about 43Meg. I have a real soft spot for this one. Back in college, I was wandering the library stacks one day looking for something interesting. A book caught my eye. It was a black hardbound book about 2 inches thich with the simple title Manual of Operation. Of course, my curiosity was piqued; I just had to take a look. I'd never heard of the Mark I, but I was absolutly enthralled. I credit that find with much of my interest in the history of computing. By the way, anyone know of an emulator for the Mark I? Brian L.
