I've never seen a chip with that many wires... I've only ever used Old Crow, MM3, and some older ones on circuit boards... And they did a terrible job soldering them on. Fudged up the PCB. Must have used a 50W iron or left the iron on too long.
I must have a clone in this world--she's clearly as bad as me at soldering =^_^= I'm curious what lines it's attaching to. Is our favorite SCEx line there? I don't remember the PS1 board layouts enough anymore.
Seems to be the ancient pre Old Crow modchip. Old Crow mentions it in his chronicles. It's not stealth so it would be advisable to replace it with something else, like Mayumi.
prob a china clone chip. I seen loads of them. there was a time when I was in PK and got my original xbox modded cost me £15 including the work and loading of unleashx. I was like yeah matey gimme some of that. upon doing it he pulled out this eprom chip and soldered in on to various spots. I was like Waaaaat???? but hey it worked like a normal Xecuter 2 chip ended up selling the console for £100
Thanks for the link, that was a fascinating read - I'd never heard of this Crow guy, sounds like he was quite the pioneer back then. Cheers!
Yeah, that's the original modchip - although that was obviously after they stopped trying to hide what the chip was - the early ones had the last 4 pins hacked off the package and the numbers sanded off the chip to try and slow down reverse engineering attempts. It's also a pretty crappy installation - even this one from back in the day is a lot cleaner. http://bayimg.com/GAGNKaAFB It's been a very long time since I looked at that chip, but looking at the board I have here, the signals seem to be Power / Ground / Mechacon Clk out / Reset / Door SW / Comparator input (aka Gate) / Comparator output (Aka Data / SCEx) / CD Limit SW / FOK from RF Amp / TZC from RF Amp IIRC, the way the chip worked was to wait for the limit switch to operate (CD optical pickup at the start of the disc), then wait for the FOK signal to assert (focus servo locked up), then wait for the TZC signal (tracking servo locked up) - then it pulled down the comparator input (to block the wobble signal from the disc) and injected the fake SCEx data on the comparator output. If the door signal was detected, it restarted the sequence. On the later chips, they got rid of the door / FOK / Limit / TZC pins and just stuck a delay in there.
