Recently, I asked the following questions:

=>Can you put both 4MB and 1MB simms in a NeXT?  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.
