It should accept any FPM parity (36 bit) SIMMs. One bank consists of two
SIMMs. In fact, it uses long word parity, i.e 33 bit SIMMs like the
AS500. I think it can use only 8 MB and 32 MB SIMMs.

Well. By two SIMMs, look if they work and by additional 6 if they do. I
have a 300X with 256 MB RAM, thats nice.

In an other mail Zane isn't sure if it uses 72 pin SIMMs or proprietary
RAM. All models of DEC 3000-300 use 72 pin SIMMs. The DEC
3000-[456789]00 models use very special 100 pin SIMMs and they need 8
per bank.
