APPENDIX A TECHNICAL COMPARISON OF FIVE EARLY BRITISH COMPUTERS

The sample electronic stored-program computers to be compared are: Setting aside the SSEM, the other five together represent the different types of machine available for scientific and engineering applications at the start of the computer age. It is difficult to compare the end-user capabilities of these machines in an even-handed way because of the significant differences in their hardware architectures. The following table, which should be read in conjunction with its notes, gives a reasonable comparison of their basic technical characteristics.
