I came across http://www.youtube.com/watch?v=1MkHGeE1iEY#t=9m39s this YouTube video about Mirtone and Mircom’s history, recently posted on the latter company’s channel, and noticed what appears to be a Simplex “4016” panel in the background at 9:39. A quick Google search about this system gave me almost no results except for a https://buyandsell.gc.ca/cds/public/2013/05/29/ed648e98f97a43a3a06d94d21cadef7f/ABES.PROD.BK__FK.B285.E61819.EBSU000.PDF bid solicitation from the Government of Canada (page 23).
Does anyone know if the Simplex 4016 actually exists or have any information about it? The label on the system seen in the video is extremely similar to the one on the 4004 and 4005, yet I’ve never seen one of these panels or read anything about them.
If it is indeed a real panel, my guess would be that it was perhaps made by Mircom for Simplex, but the obscureness and elusiveness of this system (that may or may not really exist) makes it very hard to find anything about it.
