Laser Magnetic Storage International (LMSI) was a subsidiary of Philips that designed and manufactured optical and magnetic media.[3] It began as a joint venture between Philips and Control Data Corporation.[4] It later became Philips LMS.[5]
Products
[edit]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.

CM 153: 8-bit ISA (coupled with the CM 100 and the CM 201)[26][27]3D rendering of the LMSI CM153 ISA CDROM interface board - CM 155: 8-bit ISA (coupled with the CM 100, the CM 201 and the CM 210)[28][11]
- CM 50 interface: 8-bit ISA (coupled with the CM 50)[29]

- CM 260: 16-bit ISA (coupled with the CM 206)[31][26]
- Motherboard-integrated
- Certain Tandy Sensation models featured a LMSI controller PCB connected to the motherboard.[32]
- 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
- Pro Audio 16 LMSI
- Generic 16-bit ISA cards with the Aztech AZTPR16 DSP (FCC ID 138-MMSN808)
- Magnetic products were geared towards corporate mini computer environments (like the IBM AS/400):[33]
