Overclocking FZ-10 and the save memory upgrade

[bulletbob]

It's been a while since I have been on, but.....
I finally got back to where I can mod again. There's a few things I would love to do to my 3do.

1 is over clocking.
I think that pin 14 is the clock speed input. Is there a multiplier like the Dreamcast? Or can I link up a 25 MHz crystal to that pin with a 5v power input and switch? According to the arm60 manual the processor can handle 30mhz. Maybe that would be over kill for doom. Of course a few videos are on YouTube but no explanations on how to do it. Is there a schematic for the board on where to find the 5v? Search YouTube for 3do overclock or 3do pin 14.

2 is the save game memory expansion.
I have seen a few vids on people having soldiered a second memory chip with switch, piggyback style onto the 3do, but again no how to video or pics. I have a dead 3do laying around so the chip won't be hard to come by. Where is the chip? What does it look like ect..

I will be ordering the parts from evilbay. Any hints or suggestions welcome.
I promise if I can get it to work I will post pics.

Well I made a little progress... I have not really done anything yet but take the top off and look around. There are 2 crystals the one by Clio has 25.04R41 on it. Maybe the 25 MHz for the gfx card. The second is by madam, it has 50.00KSS4M. I think that's the one I need to replace, no proof just a gut feeling. I would like to be able to run a switch between it and switch between stock and oc. But it seems easier to just replace the 12.5mhz with a 20mhz. I wouldn't want it going so fast the most games wouldn't play properly. But doom and need for speed could use a little speed boost or a lot in dooms case. Also I have no means of testing the MHz or what tool to use for that. I have a simple multimeter.

I do not know what the sram chip looks like so no dice there. Also I can't seem to find my broken fz-10 so I couldn't desoldier and piggyback them anyways.

I found a small electronics store that has my parts, crystals, flat ribbon cables and switches, so no evilbay . I'll keep you guys informed of anything I can get done.

Hey, welcome back. Hope you can make progress with it.

Where is that thumbs up button?

Hi.
Here some details about NVRAM-memory mod for Panasonic FZ-10:
You need to solder second chip on IC350. Any kind of 28-pin static-RAM 8bit x 32K/256kbit is ok.



Bend both pins №20 (CS) and connect them thru simple switch with two resistors (10k).



Also, the good idea, to solder extra capacitor between VCC of IC350 and GND.
Now you have 64k for save-files. Actually it work like two different "memory card" with switch.
