There's no logical reason why a 2-chip SIMM shouldn't work anywhere an eight chip SIMM works. "Logical" in the digital sense. There may be an analog reason why a two-chip SIMM won't work.

I've used two and three chip 32 pin SIMMs from c. 1990 in Macs with varying success. For obvious reasons, I used 1MB SIMMs when testing 68000 compacts.

The LC and LCII seemed happy with two and three chip 32 pin SIMMs of different sizes.

The Plus and SEs that I tested hated two and three chip 32 pin 1MB SIMMs. They ran happily on eight or nine chip SIMMs.

It is a case of "what works". I would not presume that an SE/30 works with two or three chip SIMMs because the technology did not exist when the SE/30 was designed. I would *expect* that an SE/30 works with suitable eight or nine chip SIMMs.
