Here's an interesting note: when I bought my se/30, i tranferred in to it
2 megs from an old SE, marked "-15", which i presume means 150ns. (I also
put in 2 meg from a mac II marked "-12"). I have been using this w/o any
problems for about 9 months, and i routinely fill up memory with many
different programs. Dont ask me why it works, but it does.
