  1. DEC PDP-11/03 switch paddle, LED receptacle and console board

    I have an MDB Systems workalike LSI-11 backplane which I am starting to get working. I thought it would be nice to build the DBCOK logic and console switches to have the same look and feel as the original PDP-11/03 console so I scripted up the specific DEC switch paddle and LED receptacle as part of the project (which is ongoing) so they can be 3D printed and use a tiny Arduino to do the powerup sequence.

  5. IBM System/360 and System/370 console button replica inserts
