IBM Model M USB-B Mount - UPDATED

prusaprinters

Remixed from the break-out board - I'm using USB B cables for a more positive, robust connection for both my model MsI'm doing internal soarer's converters using Arduino Pro Micros connected to the original IBM controllers. USB from the pro micro goes to the outside world using a panel mounted USB B socket.This is connected to the mount via two M3 x 12 cap head screws, and then the adaptor slips down onto the two posts in front of the keyboard lower case cable cut out.Prints with minimal support - I added a little to the lower edge of the mount to prevent it sagging during printing. [UPDATED 31/05/2023]New version that allows the adaptor to sit on top of the original controller board after a few alterations. The original is still works if you're swapping out the IBM controller completely, but if you are using it with a convertor like I am you will need the new one.Still prints without supports. I've include pics of my modifications to the IBM board to get it to fit - but in a nutshell you will need to:Remove the original SDL connectorRun 4 wires - one each for the +5v, Data, Clock & Ground - long enough to reach the soarer's convertor (I'm using an Arduino pro-micro) and have it out of the wayRelocate the capacitor on the board that's behind where the SDL connector was - I added fly leads to it and moved it out of the wayRemove a little of the plastic on the USB connector case to allow the wires to run under it.
