Best get the new circuits in now; if any bugs pop up well have time to correct them in the next few days. After that there mightnt be an opportunity for months… . The test was perfect; such things were more or less standardized. Problems which required a fair sampling of the great machines stored memories were used. Dr. Albie checked the solution speeds on the various tests against the speeds recorded with the old control circuits. He
