I've suddenly found myself desperately in need of the following manual. It used to be
available at Wilber Williams' Computer Museum web site, but of course that site has
shut down and I don't know of any mirrors :(
It was located here:
http://www.computer.museum.uq.edu.au/pdf/DEC-11-H740A-A-D%20H740D%20Power%2…
DEC-11-H740A-A-D H740D Power Supply Maintenance Manual
Thanks for any help!
