The update can be described as mechanical calculators extremely troublesome, within the calculator installed thousands of parts, when faulty maintenance personnel must be dismantled, replacement parts, reassemble, and then the entire machine for verification, to ensure that new parts can normal operation. At the time, this channel complex program every few weeks to once or twice.
Recently, Mark Glusker removed the Monroe PX-1421 housing, this computer is a complex internal structure was able to show in the world
