Need help modding model 1 saturn with model 2 modchip

[mysterio82]

I need help with modding a model 1 (ovel button) saturn. I've modded my model 2 with 32 pin IC no problem, and used my spare mod chip (had my experienced with soldering and knowledgable on chips father alter it following racketboy's tutorial) for my model 1. Here's the issue- with mod chip installed, saturn gets no boot up sequence, just shows Sega Saturn image, then goes blank, whole time the disc drive acts dead. If I remove the mod chip, and have the ribbon from the drive go into the saturn board as normal, the saturn boots up just fine.

I did notice that my model 1's motherboard is NOT the same as what's pictured. The board that's pictured looks like early model 1 Saturn, with power and reset buttons connected by wires on the top shell. My model 1 mother board is like the 64 pin model 2 (the model I have a hard time modding successfully) just using the model 1 disc drive assembly (manufactured october 95). I can still play my backups because of my modded 32 pin model 2, but I'd rather use the model 1 because to me the model 2 is a cheap looking version of the model 1, especially the floppy eject button where's model 1 has a solid button. Plus having a backup Saturn wouldn't hurt (my most treasured console).

I'll post some pictures of my Saturn and the mod chip alteration. Hopefully somebody can see if I did anything wrong, or if the alteration to the chip following a guide for a EARLY MODEL 1 saturn isn't compatible with a model 1 saturn using a different board. ANY help will be greatly appreciated.








Sorry for the crappy quality pics as this cam is CRAP with macro. I'm leaving in a bit to get a better cam. Hopefully these will suffice for now.
