Overview
Supports speeds of 1x and 2x and can switch between them.
Electronics
The CD subsystem of a first generation PU-7-based PlayStation consists of the following hardware components:
- DSP
- Controller (with 32 KB of external RAM)
- Sub-CPU/Mecha-Con
- Servo controller/RF-amp
- Driver
Over the years, these components have been consolidated into fewer, more complex ICs.
Models (mechanism)
- KSM-440AAM
- Compatible with PU-7, PU-8 and PU-16 boards
- Can in theory be mounted on PM-41 boards after replacing the top plastic shield, but the cable doesn't have the reinforcement/pull-tab for the non-ZIF connector of PM-41
- KSM-440ABM
- Compatible with PU-7, PU-8 and PU-16 boards
- Can in theory be mounted on PM-41 boards after replacing the top plastic shield, but the cable doesn't have the reinforcement/pull-tab for the non-ZIF connector of PM-41
- KSM-440ACM
- Compatible with PU-7, PU-8 and PU-16 boards
- Can in theory be mounted on PM-41 boards after replacing the top plastic shield, but the cable doesn't have the reinforcement/pull-tab for the non-ZIF connector of PM-41
- KSM-440ADM
- Compatible with PU-18 and PU-20 boards
- KSM-440AEM
- Compatible with PU-22 and PU-23 boards
- KSM-440BAM
- Compatible with PM-41 boards (PlayStation One)
- Can be mounted on PU-7/PU-8/PU-16 boards after replacing the top plastic shield (these boards have a ZIF-connector, but installation works fine nonetheless)
