PDP-12 Restoration at the RICM

That got me thinking: "This is the DW8E-PC Omnibus Expansion Chassis. The boards at the top convert the Posibus signals from the PDP-12 to Omnibus signals on the backplane. The Omnibus contains an LE8-FA LP01 controller, RK8-F RK05 controller, and a PC8-E PC04 paper tape reader/punch controller. It only supports one data-break controller per Omnibus. If we add more flip-chips and then we could add an RX8E controller for the RX02 floppies." Or, if you *removed* the RK05 controller, could you substitute an RX8E without modification? A pdp-12 booting from a floppy disk would be an... interesting site to behold!
