For anyone like me who wants to see all the icons but lacks the necessary hardware/software:

Download the icon volume you want to see (ie Springfield01.sea)
Fire up the OS8.5 online emulator at InfiniteMac infinitemac.org/1998/Mac%20OS%
Drag and drop the .sea file into the emulator.
Open "Downloads" folder in the "Outside World" folder.
Double click the .sea file to extract the contents.

NOTE: If the emulator complains that it can't open the file just change the suffix to .sit and try again.
