If we can id the Chicago double-sided key Mike _does_ need, I can
probably make it.
The CCL 4T1427 key, which is NOT what Mike needs, would be cut on an
Ilco S1003A blank, cuts 1427 bow-to-tip.
The CAT99 key I see referenced in the list archives (might open a cab

The cpmtools has a diskdef for the p112 formats. One could therefore
