The latest issue (v28i2) has a few articles on the ENIAC as well as one each on Univac and Oedipus, a machine used in the UK for cryptanalysis in the 1945-1955 period.
The article I'm most looking forward to reading is Graduate Student Experiences at Illinois by R.E. Miller.
This personal account describes various experiences of a 1950s graduate student who worked at the University of Illinois’s Digital Computer Laboratory. Anecdotes recount some of the era’s rigorous academic requirements and early work assignments performed for the IBM 701 and Illiac computers.
