On the right are 4 more modems. I did a system to drain all the Chucky Cheese's in the US in the early 80's (70) total, by outdialing into each one. The way I could dial was to select a line and dial it, then drop off once the call progress indicated a connection. It was able to run 5 modems with my software before overwhelming the Microdata Reality I was draining into, but the physical hardware could have run all the rest of the slots full of modems with the autodial rig. I have several of these racks around, when the 38400 56k and up quadrature modems started to be popular in the 90's this stuff was all scrapped. Jim
