Hello all, Long time lurker, extremely rare poster, I was reading the Wikipedia article on the IBM 1620 and became quite intrigued. I know that there is a simulator for it on SimH but I have never ran or simulated any card-driven machines before. I have all the documentation and the ibm1620.zip file try Monitor, Fortran-II and possibly GOTRAN but I have so many questions. I read the SimH documentation which gave me some understanding but I don't know exactly how the card decks work, how to install Monitor or how to boot Monitor once it is installed since I know you have to boot off a deck. My final question is, is there an easy to use card-driven machine to cut my teeth on? Also, any anecdotes on any of the old IBM computers would be both welcome and greatly appreciated. Thanks in advance Ray
