[Duo2400] 2400 Memory?

[Ralph Mawyer]

Tom, 60ns SO-DIMM in 64MB flavor should work fine.

Can we assume:

1. yYour original 16MB PB2400 with an empty slot  worked fine, but 
adding a 16MB, 32MB and 64MB didn't?

2. After installing the memory the machine booted without a problem, 
but only showed 16MB RAM?

I'm thinking hardware or install problem.

Running OS 8.6 or 7.6.1...or something in between?
