Colcha 1

Colcha 1 is reconstructed from its Applesoft BASIC listing and the original shape data. The program uses two different shape tables during each cycle: shape 3 from the external TABLE/PROGRAM library at $6000 for the first two processes, then an embedded two-shape table at $0300 for the final process.

The work is silent: unlike the later sound works, its listing contains no Apple II speaker routine. Timing is calibrated against the three-run Virtual ][ recording and intentionally increases as the shapes become larger, approximating the growing processing time of the original Apple IIe.
