Well that's super interesting! If this turns out to be true, I'll buy a fistful of them to make sure I'm covered in future if they're known for being flaky. I was hoping they'd be a general processor rather than a firmware filled microcontroller particular to each board. I'll wait to hear back...
I've emailed the guy looking at my board for me (I'm just SW of Ballarat, and Bruce is in Sydney) and I'll let you know as soon as I hear back from him about the part number of the chip. I was hoping that these are interchangeable between boards, it would suck if they're like a microcontroller...
Thanks so much for the explanation - I think this is sometimes why I enjoy vintage computers - the standardisation wasn't really there so you get all sorts of interesting exotic stuff like this that definitely piques my interest.
So if I can source a spare, I should probably see if I can source...
Oh man, you guys are awesome! I just checked in and am blown away by the responses! Thanks so much - what an active and welcoming community! I'll reply directly to everyone now
I have an LC575 board that I sent to the great Bruce Rayne here in Australia to repair for me that suddenly died in the Colour Classic I had it in.
After a fair amount of troubleshooting he's let me know that it's the cuda/egret chip that's at fault and that he doesn't have a spare board to...
