So, I am restoring a Macintosh IIci https://68kmla.org/forums/index.php?/topic/25123-macintosh-iici-wont-start-up/, and I thought it might be nice to run System 7.5.4 on it. Why 7.5.4? Look http://www.fenestrated.net/~macman/SysReview/#Summary at this. 7.5.4 crashes some PowerPC Performas. I don't even have any PowerPC Performas. (I was also planning to do http://www.fenestrated.net/~macman/755/.)

Does anybody know where to find System 7.5.4 (preferably as an updater to 7.5.3)?
