Sony cut the external ports from the Playstations with model changes and cut the opening mechanics with the PSOne(the small).
There were special white blue and black units for video CDs and developers.
The PSX is still good for playing music CDs with the 2x CDROM drive.
It lacks computer functionality and RAM,me had 2 defective incomplete units and couldn't build a MIPS computer from them,because of missing skills too.
On my working
unit I soldered a different colored power LED in.
If you have a mod chip,you could use homebrew games developed with a gcc
MIPS R3000A cross compiler and special libraries.
