We are considering buying =>some 4MB simms for a NeXT that now has 8 1MB simms. Will we be able to keep =>the 1MB simms in and add 4MB simms? Here is a summary of the answers I received: The SIMMS in the next are arranged in banks of 4, with 4 banks or 16 SIMMS total. Each bank must have all the same type (1MB/4MB) SIMMS. You can have both banks of 1MB SIMMS and banks of 4MB SIMMS, but you can't mix them within a bank. I believe that you must have four SIMMS in each bank, i.e. no partially filled banks, though I'm not positive on this. Thanks to all those that responded to my question.

Each SIMM is 8 bits wide. Four SIMM's are required to make a 32-bit wide word, to match the 68030's data path. Article 7369 of comp.sys.next: >From: rca@tahoe.cs.brown.edu (Ronald C.F. Antony)
