Question: Will the M0707 memory kit work in a Macintosh SE?
Answer: No. There is not enough room in the Macintosh SE's chassis to accommodate the larger chips.
Question: What kit does Apple reccommend for upgrading those machines?
Answer: The standard 2MB memory upgrade was the only Apple solution available for the Macintosh SE. Third-party memory solutions are also available.
Question: Has the Macintosh SE frame been changed to support the larger DIP SIMMs (M0707)?
Answer: No, the Macintosh SE frame has not been changed to accommodate the larger DIP SIMMs.
Question: Is Apple still using the 150ns 256K SIMM chips in the M0218?
Answer: The 1MB upgrade with the 256 kilobit chips used 120ns chips. This was necessary for the chips to be able to work in the Macintosh II. This upgrade was also used to expand a 1MB Macintosh II to 2MB, and the Macintosh II requires 120ns chips.
NOTE:
The 150ns 256 kilobit chips were only an issue when they were
removed from a Macintosh SE that is upgraded using the 2MB upgrade. If
these chips were then used in a Macintosh II, memory errors occurred.
