Transplanting the components to a newly fabricated circuit board is your only option (if you are good at soldering). Otherwise, you can ask someone to do this for you or sell the Mac as-is.

There is no problem with the availability of PLCC sockets in general. You just need one which sticks on the non-socketed, soldered PLCC chip from above. This is a very rare use case! You could buy a few different sockets and try them. Maybe some will work.

Looks like Mouser will stock the Z85C30 again in 2026..?!

Excellent!

Very impressive! Is the emulation running on different host CPUs or everything on the same one?

That‘s the way to do it! 😃

Can you quote any source? TI still lists the 75175 as active…

Maybe this helps: delete the preferences in the system folder, then zap the pram

HD SC Setup can probably only replace its own (Apple) drivers. Best try other apps, maybe Silverlining might be able to do this. Or just re-initialize it….

This is very strange… Did you already try some „known working“ BlueSCSI image? Is the BlueSCSI terminated? You could also try to set the startup disk and then restart. The original HD is no longer connected?

I guess you didn’t plug that cable in while the system was running? You are not supposed to do that 😉

You could try to allocate less memory to the routing and zone tables. The setting is inside the Internet Router Application.

Your analog board is certainly repairable; if you decide to part with it and the CRT, please consider offering it for sale here! 😊

Possibly. Best check for continuity and make sure you didn‘t create an internal short circuit

It‘s an inductor (coil). Are you sure it‘s damaged?
