Thanks for that link. I've got a Flower Power iMac which I adore but the inside bezel is all broken up and I don't dare mess around with it until I get a new inner bezel. Now at least I have some options.

Some models of the SCSI2SD are over $100, and all the ones I've seen on ebay are similarly priced, but go to Inertial Computing's website https://store.inertialcomputing.com/SCSI2SD-s/100.htm and they start at like $60. It's not the fastest model, but should be fine for a 7500.

I'd probably be interested in probably a half dozen sets. After all is said and done, you might be wishing you'd ordered more

The simms on that memory card look like 256K simms, which I don't think will work. You're going to want a pair of 1mb simms on that card. You can try removing the 256k simms and reinstalling the card, which will give you 2mb to play with which is the minimum for system 7.

Seems like I hear a lot about people having a dead Egret chip?

Seems like the IIfx is very particular about SCSI devices, and required special terminators internally and externally. Maybe they were active terminators or something, all I remember is at the time it was something special.

On ci #1 and cx #3, the cards closest to the power supply are ethernet cards rather than video cards. The 15 pin connector there is an AUI connector ci #2 might get better results if you pull that single ram simm out of the bank. edit: You may be able to find documentation on your video adapters in the Peripherals section, "Video Adapter Docs Scan Dump" thread.

For FDHD you need to move the roms *and* the SWIM chip

You must be living right! Congratulations

The Dead Mac Scrolls, which is available out there on the 'tubes as a PDF, shows pictures of common faults and their repairs for the Plus and SE. It's a great resource. https://vintageapple.org/macbooks/pdf/The_Dead_Mac_Scrolls_1992.pdf

Ha! I was looking at that ad an hour ago. I wasn't too interested in the 7200, but hmmm that monitor and keyboard... Congratulations, looks like a nice score!

Wow, I'm really surprised that any USB drive could write 800K disks. Good to know.

Hope it didn't kill the cache card or the logic board!

If you have a dvd burner, you can download a disk image from Macintosh Garden and burn a copy. They have images of the retail disk and might have an image of the original disk for your iMac/PowerMac G5.

Maybe the gear was designed to be the first to break as sort of a "fuse"; if too much torque was applied or if something else went wrong, that particular gear would give way and spare all the other gears. I'm probably giving too much benefit of the doubt or credit for being far-sighted but who knows.
