1002 Models

We do not recommed installation in 1002 playstations - as these suffer from a laser head problem that causes skipping, and often fail to load games. This usually occurs after around 30 minutes of playing. This is caused by an overheating problem due to the proximity of the laser head to the power supply.

If you install a chip and see this problem, this is not a fault of the chip. Whilst it is possible to replace the laser head, this only delays the inevitable. If your PSX suffers from intermittent reading problems before installation, it may be best to sell it now and replace it with a new unit. No models after the 1002 suffer from this problem as the laser heads were moved away from the power supply.
