According to everymac, the first rev 233MHz model could not accept two
256MB DIMMs, but the 266MHz and 333MHz (as well as rev B 233MHz) systems
should be fine.  You want PC66 SDRAM.

My experience with a similar vintage of Mac is that it will not see the
module at all, if it is incompatible.  On my B&W Power Macintosh G3, it
didn't like high-density DIMMs.
