I worked at ICL at Artarmon in Sydney Australia for several years back in the 1970`s. We used the 1004 for various accounting tasks. As workshop supervisor, I was given the use of it to create analysis programs for various computer board faults with quite good results (basically statistical analysis). When it was scrapped, I was given it for use developing UFOCOMFILE, a system of cataloguing and sorting UFO sightings. I eventually move it to a 1904 but those formative plug wire wiring program sessions were most enjoying and extremely easy to implement. With the on board relays available, I was able to program 62 steps with many branches. Needless to say that the board was absolutely choked with wires and weighed a ton. Fantastic memories for me. I am currently working on a relay implementation of a BR133 but making it 16 instead of 15 bits. All the best.
