The last digit of the PlayStation model number denotes the region in which it was sold:
- 0 is Japan (Japanese boot ROM, NTSC:J region, NTSC Video, 100 V PSU)
- 1 is USA/Canada (English boot ROM, NTSC:U/C region, NTSC Video, 110 V PSU)
- 2 is Europe/Australia/PAL region (English boot ROM, PAL region, PAL Video, 220-240 V PSU)
- 3 is Asia (English boot ROM, NTSC:J region, NTSC video, Wide range 110-240 V PSU)
Quality of construction
The first batch of PlayStations used a KSM-440AAM laser unit whose case and all movable parts were completely made out of plastic. Over time, friction caused the plastic tray to wear out—usually unevenly. The placement of the laser unit close to the power supply accelerated wear because of the additional heat, which made the plastic even more vulnerable to friction. Eventually, the tray would become so worn that the laser no longer pointed directly at the CD and games would no longer load. Sony first addressed the problem by making the tray out of die-cast metal, and additionally also placed the laser unit farther away from the power supply on later models of the PlayStation.
Some units, particularly the early 100x models, would be unable to play FMV or music correctly, resulting in skipping or freezing. In more extreme cases the PlayStation would only work correctly when turned onto its side or upside down.
