Hamilton Spectrograph Slit Room upgrade

Though the slit room upgrade was completed before the Hamilton II upgrade, the documentation is folded into the same website.

As shown on the EL-4034 drawing, the Galil RIO-47100 Remote Input Output controller, RIO, provides 16 digital inputs and 16 digital outpiuts. Though we haven't used them for this project, the controller also includes 8 analog inputs and 8 analog outputs. As the top, left of the assignment table shows, the first 8 outputs are noted as 'High Power'. Galil has included these outputs for driving equipment like brakes and relays directly. These outputs are used to source current rather than sinking
