LMSI developed a proprietary CD-ROM interface. Early iterations relied on many 7400-series chips – on the CM 153 card for example. Later on, this bus was based on the highly integrated NCR chip – NCR © DIGBIE LMS 97644845-00 0390471 on the CM 260 for example.

The proprietary 16-pin LMSI CD-ROM interface was relatively short lived and existed on LMSI interface cards and a few ISA sound cards. These sound cards only have internal LMSI connectors, not the external DB-15 connector for external LMSI devices (the DB-15 on sound cards is the game port/UART MPU-401):
Sound Blaster Pro 2 CT1620
Sound Blaster 16 ASP CSP CT1780
Media Vision Jazz 16 LMSI
Pro Audio Spectrum LMSI
