References:The lecture will illustrate how code is represented and executed in computer memory. The computer used is the fictitious Epsilon originally suggested by Dopping 1966. (Epsilon comes from the Swedish description "Enbart pedagogisk syftande, i litenhet oöverträffad nonsensmaskin).
The first implementation at Åbo Akademi was written by Törn in Fortran during the midsummer eve in 1970, and was used in introductory courses for more than a decade. This implementation has been lost in computer upgradings over the years. Since 1996 Epsilon has again been on the agenda and one of our students Fredrik Sandström has written the implementation used here.
