Until the release of CaDD PC99 Suite, CaDD offered PC99 Stage 6 {Full | Light} and The Cyc separately. Because of licensing arrangements with Texas Instruments and third-party vendors, you had to be an owner of PC99 Stage 6 {Full | Light} to order The Cyc. By bundling PC99 DOS, the PC99W emulator, and The Cyc in CaDD PC99 Suite, this restriction no longer applies.
