Parent

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

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.

External CD-ROMs, LMSI interface
  • CDD 401: 1× speed (rebranded CM 221)[6][7]

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

  • CM 250: 8-bit ISA (coupled with the CM 205)[30][26]
  • 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]
    • LD 510: internal SCSI MO drive
    • LD 520: external MO drive
    • LD 1200: external WORM drive[26]
    • LD 4100: cartridge optical storage[34]
    • LD 6100: external WORM drive
    • LF 4500: cartridge optical storage[34]
