What Modchip for a SCPH-102 (PSone)?

What Modchip for a SCPH-102 (PSone)? *SOLVED*

What Modchip was it again that you use in a SCPH-102 PSone?

Stealth something wasn't it??

Does anyone have the files so I can write it to a EEPROM / ROM???

 

You dont write it to a eeprom or rom, they are storage. (which is in the name really, the M stands for memory).
You want to write to a Microcontroller (pic chip in this instance)

 

here is the hex for PAL psones.
It has BIOS patch so it can load NTSC without a boot disc.

 

Ah, thank you very very much Bad_Ad84 and Jinn.

I will buy a PIC12C509-04/P IC and flash it on.

Thanks again!

 

Oh, is this a MM3, Onechip or Oldcrow hex?

I have several SCPH-102 layouts for soldering the 8 pins to.

 

It's and 8-wire PAL ONLY Hex code.
I think it's based on 1chip or it is a 1chip hex.
Use the 1chip diagrams.

 

Thank you :thumbsup:

*SOLVED*

 

Aren't the C chips OTP?

They are replaced with F which are cheaper and rewritable. Oh and still in production, so Microchip still give samples.

 

OTP?

I was going to get a P.

Does not bother me if they are not re-writeable. I only need to write once to it and label it for the PSone...

Samples you say. lol. I just get them from eBay...

OTP = One Time Programmable. Basically, you cant erase and reprogram them if the hex is incorrect or what ever else.

PIC12F509 is the replacement chip, PIC12C50x is obsolete.

 

http://www.ebay.com.au/itm/10x-Micr...185?pt=LH_DefaultDomain_2&hash=item33679f7f69

Is this correct?

PIC12F509 = OPT
PIC12C50x / PIC12P50x = NOPT

How is the PIC12C50x obsolete? It is still good right??

 

PIC12F50x = Flash (rewritable)
PIC12C50x = OTP

If you look in the specs you pasted above, you will see the PIC12C50x memory is listed as OTP.

 

Ah, I see.

Thanks for clearing that!

 

And obsolete just means its not in production anymore (i.e. Microchip have stopped making them) and the PIC12F50x chips are their direct replacement - as recommended by Microchip.


Long as the OTP thing doesnt bother you, then they are both equal in performance.

However, the flash versions are cheaper here, rewritable and you can get samples from microchip if required.

 

I know what obsolete means, but I was wondering why the company stopped making them

Yea, I guess I will just go for the flash version then...


Thank you very much for all your help! Much appreciated!!

 

Companies generally stop making them due to low demand or a cheaper alternative

 

Ah ok. Thanks :thumbsup:

(for reference if anyone stumbles upon this topic: if anyone cant find the onechip / 1chip diagrams, I have them)

 

garyopa's 12f629 port will work in a psone (is not full stealth tho)

 

I use PIC12508C and the one chip works fine.

 

OK I can use this as my programmer right?

You can see the list of PIC's it will support, but none are the PIC12 version. It should still work of course, right?


Here is the PIC
