This was a relatively common computer in its time as its $12,000 cost was then considered a bargain. Much used in university research departments etc or for controlling industrial machinery. The row of tab switches on the front panel were used for reading & writing to its memory in binary. The initial "bootstrap" program had to be laboriously loaded in using these front panel switches. This would typically have a teleprinter terminal connected to it in order to interact with it & print out results. See our teletype under Teleprinters category.
