The IBM Personal System/2 CD-ROM Drive Technical Reference is IBM's 38-page programming reference for the PS/2 CD-ROM drive, part number 15F2134, form number S15F-2134-00, First Edition, March 1990. The scan is image-only and has no text layer.

The drive is a read-only SCSI device for 120 mm discs of about 600 MB conforming to IEC 908, attached through a SCSI adapter that can take up to seven SCSI devices (p. 1).

Contents

From the contents page (p. iii):

  • Description (p. 1)
  • Programming considerations (pp. 2-8): Inquiry, Read Capacity, Read Extended and Request Sense, with the sense keys (p. 5) and additional sense data codes (p. 6); Send Other SCSI Command (p. 8)
  • SCSI commands (pp. 9-29): Test Unit Ready, Rezero Unit, Mode Select (with the page 01 error recovery and page 02 disconnect/reconnect parameters), Reserve, Release, Mode Sense, Start/Stop Unit, Prevent/Allow Media Removal, and the drive's own audio and caddy commands: Audio Track Search (hex C0), Play Audio (C1), Still (C2), Set Stop Time (C3), Eject Disc Caddy (C4), Read Subcode Q Data and Playing Status (C6), Read Disc Information (C7) and Read CD-ROM Mode (C8)
  • Connector (p. 30): pin assignments of the 50-pin SCSI signal connector

What this manual does not contain

There is no service information: no FRU numbers, disassembly, optical or mechanism adjustment, power connector details or component values. It does not cover the SCSI adapter, which has its own technical reference.

What it settles

The sense key and additional sense data tables (pp. 5-7) define the error conditions the drive reports, and p. 30 gives the SCSI connector pinout.
