You may be in luck! My newly modded Saturn was manufactured on August of '96 as well!

Good luck and keep us posted.

Good News....I recieved my new saturn today...and as promised it has a manufacture date august 1996 .. and as predicted it has the 32 pin ic and the mod board worked perfectly... any one want to buy a perfectly good saturn that I won't be using..=) I would even throw in a few games...=P...Im happy now=)

what do i do if I have no IC chip to solder to and I have a two wire mod?

 mal May 29, 2002
You have a few options.

1 Get a 'pass through' mod.

2 Get a Saturn that can use a two wire mod.

3 Get an 8.467MHz crystal, a 74HC04 Hex inverter, a 1K smd resistor and a 100uF electrolytic capacator and mod your mod. If your soldering is good it may be possible. I don't know if anyone has tried this yet.

Beyond that there's always swapping...

"Get a 'pass through' mod."

anybody know where can I get one ?

my Saturn is the 64 pin model, manufactured in June 1996, Model No.: MK-80000A

any chances to the Lik-Sang modchip work in it ?

or just with the "pass through" ??

Thank you

lordcoxis... was talking about getting some pass through mods last week. You might try getting in touch with him.

As I'm sure you've already noticed, unclecuddles... posted on the second page of this thread that he's successfully modded a 64 pin Saturn with a two wire mod.

 BloodyKnuckles Jun 1, 2002
is there a chance that lordcoxis or anyone else would trade me for one of the pass through mods? I have the two wire mod and its just fine, I just can't use if due to the lack of an IC chip in my saturn. any info would be great

Look at Mal's recent thread on the Saturn forum (entitled "I just modded a 21 pin Saturn") - I think it may interest you

I just received my modchip in the mail and opened my saturn. Dissapointingly it has the 64 pin chip. What is this stuff you are talking about with bridging to 0014 or 0019? What does that mean? I thought all I had to do was solder it to pin 8 on the chip. I haven't attempted the mod yet.

 Curtis Jun 10, 2002
The 0014 and 0019 bridge is supposed to solve some compatibility issues with some Saturns. By the default, most mods are setup with the 0014 bridge (a blob of solder between two points on the modboard, one of which is marked as "0014"). If this configuration does not work for your Saturn, you can remove this bridge and use the 0019 bridge.

Yes, you are just supposed to solder to pin 8 of the 64 pin chip (as per the playthegames.com instructions), but if you are feeling adventurous, you might be able to help mal out with his problem. See his topic "I just modded a 21 pin Saturn" in the Saturn forum. This mod is easier to do, but as yet is not confirmed to work with 64 pin Saturns. Be aware that there is a remote possibility that trying this could damage your Saturn, but it's probably no more likely that damaging you Saturn by following the playthegames.com instructions.

Hmm I installed it and I tried to boot up an original game and it just took me to the audio cd menu. I will try a backup in a minute. Maybe it has something to do with this bridge stuff..

 ThePanda Jun 11, 2002
Okay the backup didn't work either. The CD doesn't even spin at all from the time I turn on the system; does that indicate any specific problem? It shows the white saturn logo screen and then just takes me to the audio CD controls with a faint hissing noise in the background. It just stays stuck saying "Checking Disc Format" with a yellow and a red ball on the sides. (I guess it can't check the format if the CD isn't spinning) Any tips would be appreciated..

 ThePanda Jun 11, 2002
I see this in mal's post here:

"if the ribbon cable isn't properly inserted (either bridge):

-no boot up animation

-two large red spheres at the CD player screen

-no CD rotation

-displays 'checking disc format'"

That's the only one with a red sphere in it, but he doesn't mention any with a yellow sphere ??? I guess I should check the ribbon cable; I saw in some post that maybe you have to put it in backwards for the 64 pin version ??

 ThePanda Jun 11, 2002
Also, is the first pin sticking out on the back of the modchip supposed to be bent down all the way and touching the board? I didn't know whether it was intentional or not because some of the other ones were bent too, but not bent down all the way.

 Curtis Jun 11, 2002
No, the pins shouldn't be touching the case.

Also, the modboard in the 64 pin Saturns needs to be inserted with the electonics of the board facing the casing of the Saturn, as opposed to facing the CD assembly.

I meant that a pin on the back of the modchip is bent down all the way and touching the board of the modchip.

So it shouldn't be like in this picture?:

I tried plugging the ribbon both ways into the modchip, but I have had the modchip itself like it is in that picture both times. My ribbon doesn't look exactly like the one in that picture, mine was prebent in two places. How exactly is the ribbon supposed to be inserted into the motherboard and the modchip, I mean which direction are those blue lines or the words supposed to face?

 Curtis Jun 11, 2002
Flip the board 180 degrees fro the one in the picture, and try the ribbon cable both ways in it then.

 ThePanda Jun 11, 2002
Okay, thanks for the tip. I made some progress. The following now describes my situation:

"no solder bridge:

-boot up animation

-two green cubes at the CD player screen

-CD rotates

-displays "checking disc format"

-will then only play audio tracks of CDRs and originals"

So I guess now I have to find out more information about these solder bridges. Is there a thread somewhere that describes what and where they are? I searched and couldn't find anything.

 mal Jun 11, 2002
I'm working on variations on the solder bridges.

Unfortunately 'Real Life'βΆ is getting in the way, but I'm not giving up yet.
