for most PSOne: http://www.psxdev.net/forum/viewtopic.php?f=62&t=365
others I dont know for sure, but pretty similiar. find the pins, or use the SIO connector.
I dint use a Max232 converter, cause I used my USB serial adapter in 3.3v mode, RX, TX and gnd where enough. You might want those other connections maybe aswell for some mainly older software want to use those.

For older/Fat ps1, it apears this thread is what your looking for?

thank you very much

but I did not know that the PSONE have this posibility is that in case PSONE does not try to add the converter circuit from 3.3V to 5v? just had to connect the wires with the soldering iron is it? and resortire the port? and what is the port which I must weld to these threads?

and you do not have an idea to make a cable or a port if I can not find at home?

and if I remember the psx fat he need the cirucuit MAX or ISL to convert the tension

And thank you in advance

The PSone serial internal is 3.3v I believe. The whole MAX232 or other voltage convertion method is done purely on the assumption your going to connect to a true RS232 computer connector. If you going to use a PC or laptop that doesnt come with a serial port then you may just buy a USB serial converter, make sure its RX and TX are ttl level (3.3 alike) and directly connect the wires.
TX(pc) to RX(psone/Ps1) and RX to TX. things like DTR and RTS migth be helpfull but depends on the software you are running on the PS1. the McLaunch works fine with the minimal setup ive found.
