If it's an old Power Mac, then you may want to try and find a cheapo Mac OS 7.6.x CD somewhere (eBay maybe), for the following reasons:

  1. You can boot directly from the Mac OS 7.6.x CD and do everything from it, easy and convenient.
  2. You won't have to worry about finding floppies and making 19 discs, nor swapping out 19 floppies (it takes forever trust me I've done it more than I'd like to remember).
  3. Mac OS 7.6.1 is significantly better than Mac OS 7.5.x, especially for Macs with PowerPC processors. It is more way more stable and is compatible with some newer software which is nice. Mac OS 7.6 can be upgraded to 7.6.1 for free.

It's also nice to see people recommending my site!

not only is 7.6.1 great on PPC Mac's, it also fly's on a fully upgraded 68k. after my P475 went threw its fit it started working great. it can do stuff that i didn't think it would do. but like dpaanlka said 7.6.1 is allot better than 7.5.x. 7.5.x is known to have allot of problems that 7.6.1 dont have and 7.6.1 seem's to be more in tune and run allot better than 7.5.x ever can, plus it still has a small memory footprint
