Title: PSONE-Serial Author: mgarcia Date: 2019-08-24 19:46 +1000 Tags: 2019, Pics Comments: Open
I've just posted a long post on Dan's blog, https://psx0.wordpress.com/2013/01/22/psone-usb-link-serial I'll mirror it here:
Hey Dan, I picked up a working PSONE (102 PM-41-51) got it for an amazing prize 40AUD! And wanting to turn it into a pseudo Net Yaroze, I’m trying to figure out your CPU/pad pinout image, but it’s very low res, I guess it’s not required as there’s different versions of the MB. Anyway, here are some of my notes so far, I hope you don’t mind me adding to your tuts For anyone else wanting to do this: I found a good service manual with all PSONE rev MOBO’s pinouts, PDF’s here: https://www.manualslib.com/manual/1299556/Sony-Psone-Scph-100.html?page=10#manual Defor (from AS forum as you said) “(Pins 70-75 of the CPU on both board layouts specifically) ” which looks correct on my MB also. https://assemblergames.com/threads/add-a-link-port-to-the-psone.19777/#post-344317 I see his PSONE image (topside) is wired the same as yours https://assemblergames.com/threads/add-a-link-port-to-the-psone.19777/page-2#post-399658 (not sure which rev MB tho) So I’m still figuring out which CPU pins/Pads correspond to my MB and the serial FDTI as per your Net Yaroze cable tut http://www.psxdev.net/forum/viewtopic.php?t=1071 I’ll post a pic of my MB with that I think looks correct
The top left is from dan's post on psxdev, next is a close up of 70-75 pins.
6 is red and the pin from the CPU goes nowhere, so I assume it's wire next to the lid open switch, bottom right, My board has a resistor, which is what the psONE manual (pdf link above) has.
The embedded images are from defor's "pics of the psone topside": http://www.flickr.com/photos/defor/4318206198
On the left is the 3.3v power to the FTDI serial board, there's solder pads above the 123 numbers, 1 is positive, 3 is negative.
Would be nice to get confirmation of the above looks correct before soldering, it might also help others too :)
