A couple more for the keys file: Allegedly Control Data used a National C415A on Network Processing Unit cabinets in the late 70s, early 80s. That's an Ilco 1069-N, cuts are 12343 from bow to tip. Cut spacings are .156 .249 .342 .435 .528. Depths are 1=.250 2=.225 3=.200 4=.175.
TI apparently used Chicago C2132 on at least some 980 and 990 cabinets and CPU keyswitches. That's Ilco 1041-G. Chicago double bitted keys aren't really code cuttable as far as I know. You copy a guide key, in this case H2132, onto your proper blank. De
