If you happen to pass by Ivrea (short trip from Turin or Milan) there is a very nice small museum which showcases most of the machines mentioned. It has also a working Programma 101 and if you are lucky there might be a volounteer that can demo it. There also volounteer giving guided tours and if you are with kids you have the option to have them do a workshop (includes some 3d printing).
