I use a double-sided 32MB EDO stick in my 575 mobo which is in my Color Classic... and they don't work in my Quadra 840AV. I think single-sided RAM tends to work in the 68K macs, higher up in the Power Macintosh (like the 8100) area double-sided/double bank works all right. Also, generally 32/64MB is the biggest stick supported for the smaller stuff, save the 128MB and higher for the towers.
So your best bet is finding a cheap/free LC III/Performa or higher to test them in. Luckily, they're the easiest to get into, also. Oh, I forgot, I have a Quadra 650 that I haven't finished tinkered with yet, thanks for reminding me! By doing this you can weed out the stuff that's more than 80ns-- I think the MacTV is the only one with 100ns 72-pin requirements. As for the PM 4400 to 5400, don't worry about that, they are 168pin, not 72. I've never toasted an older Mac that didn't have a power supply or corrosion problem, but it's worth being careful about once you get to 168-pin stuff. When in doubt, use MacTracker. I'm also curious what price you'll put on the box of RAM, since I'd like to sell a box of mine too!
