Found a sound in Quadra 700/900 ROM, but can't extract.

Yep, that's the same thing that happened to me on my LC 475 back a page or two. It's because the sound chip in the 475 doesn't support decompressing the sounds. The compressed sounds are still stored in the LC/Performa 475 ROM, but it's not capable of playing them. When you boot it up, it plays a different uncompressed version of the same sound stored in a different location. It probably also skips the code that checks the PRAM to decide which sound to play too.

So, umm... why don't you hack it then, dougg3 ? Does the 475 take ROM SIMMS ?

Sadly, I don't think the 475 has a ROM SIMM socket.

Hi,

Couldn't it be modified to use sockets for the chips, like your initial IIci deal (before you figured out the SIMM)?

You're right, it could be done by changing the ROM chips. Actually, it sounds like the LC475 does have a ROM SIMM socket -- but it's not populated. So you'd need to solder in a ROM SIMM socket to the empty pads. Once you did that, you could use a ROM SIMM and do whatever hacking necessary to change the chime. I probably wouldn't want to hack the ROM to make that control panel work (too much trouble) but it would be fairly straightforward to change the startup chime using the SIMM (and as an added bonus you could also add a ROM disk to boot from)

Ah yes! I've always wondered why they're those blank solder blobs on the board looking suspicously like they sould have a socket on them! I thought it was for some kind of upgrade, like two RAM slots or something...

Very cool job cracking the code Lord Nightmare!

I had to run Lord Nightmare's code and get the latest sound files. Here they are:
