I think there may be trouble with the denser SIMMs...
I've got 4 64MB SIMMs that steadfastly refuse to work in my CS-PPC A4000 - the machine goes unstable and it thinks they're only 16MB each. Of course that doesn`t mean they won`t work in a Blizzard 1230-IV, but be warned, it might be worth checking first. 32MB SIMMs should be fine though.
Good job RAM is cheap these days!
