I did a lot of work on the development of the Reading University EPG system in the mid-1970's, working with Bill Hardcastle and Wilf Jones. I wrote the first computer program for controlling the system, running on the PDP-8 computer in the Phonetics Lab. It was hard work, using punched paper tape for the successive versions of the program. The program contained almost 4000 lines of code (assembly language, which translated line by line into machine code), while at the start of the work the computer only had a 4K core memory.
