 |
|
I have two Griffins here, one working, the other broken. Simply by exchanging parts i found the faulty chip is the one from spot B.
Unfortunately the writing on the chip is wiped away. Anyone knows what chip that is? (I found the chip on spot A is a Motorola MCS3201FN
controller, sadly i wasnt able to figure out B).
If anyone has a Griffin for sell, even broken, contact me, probably i buy. |

| I'm betting it's an ASIC since I don't see a processor anywhere else in that picture. |

Interesting pic. Never saw the inside of a Griffin before. RAM is onboard and not expandable and I guess this cable hanging is a pad replicator?
Regarding the chip, I second madman's opinion, it's most probably an ASIC as there used to be on the magicom. Unfortunately you won't be able to do much with this device as the ASIC is a custom logic chip. |

| The actual part is an EPLD. It's possible to buy the chip old stock but it's insanely difficult to build a development environment today (need the computer, design suite with dongle, programming hardware) and of course nobody has either the chip's fusemap nor logic design (not even FFE) so you'd basically be reverse engineering it anyway XD |
